If you want to locate someone precisely on the surface of the Earth, you specify her exact latitude and longitude. If you want to locate a star precisely on the sky, you need to specify its exact:
A) meridian and great circle
B) constellation
C) north and east point
D) right ascension and declination
E) solstice and equinox
Answer:
D) right ascension and declination
Explanation:
Just like we have a longitude on earth which tells us about the position or angular measurement of a body east or west of Greenwich that lies at 0° longitude, for the measurement of star's position on the sky we use RA (right ascension) that tells us about the position of star from celestial equator.
As the latitude provide us the information of position in north or south of the equator, similarly declination tells the position of star in the north or south of celestial equator.
So if some one wants to locate the star more precisely on the sky then he/she will measure and describe it in terms of right ascension and declination.

Explanation:
The recent recognition of a link between increasing rates of deforestation and increasing global climatic warming has focused new attention on the ecological role of forests. Deforestation threatens the continued existence of forests, and their loss would lead to an immediate, irreversible destabilization of the climate because the destruction of forests contributes to increased atmospheric concentrations of such heat-trapping gases as carbon dioxide and therefore to the acceleration of global warming.
The world is at present accumulating carbon dioxide in the atmosphere from two well-known sources: the combustion of fossil fuels and deforestation. Deforestation results in higher levels of carbon dioxide in the atmosphere because the carbon stored in plants and trees is released when trees decay or are burned.A third sources, the warming-enhanced decay of organic matter in forests and soils, especially in the middle and higher latitudes, is now being recognized as potentially significant. Evidence is accumulating that carbon from this source is beginning to have global effects. Thus, two of the three sources of carbon dioxide in the atmosphere are directly related to the survival and health of forests.
In the discussion about the importance of forests, however, emphasis has fallen on biodiversity, or numbers of species per unit area, especially in the tropics, where such diversity is particularly high. But forests, it should be emphasized, have a similar role in every latitude: they contain the largest numbers of developed of the terrestrial communities from the standpoint of complexity of structure and diversity of life and life forms. Forests are far more than simple collections of species, however, it is unfortunate that the discussion of biotic or living resources has been focused on biodiversity rather than on the actual ability of the land itself to support life. In order for the complete range of plant and animal life to thrive, the soil must contain essential nutrients in their proper quantities and proportions, and the atmosphere must be composed of the correct molecules in their proper proportions. If the soils were to become infertile and the atmostphere inhospitable, more than mere diversity or numbers of species would be lost, the land would become impoverished and no longer be able to support any life.
Deforestation almost invariably speeds up the loss of nutrients into watercourses. It also, as previously explained, involves a release of carbon into the atmosphere. Forests thus play a clear and critical role in helping to protect the capacity of the land to support life by increasing the retention of nutrients and in helping to stabilize the atmosphere by storing carbon.
Answer:
Deforestation is the process of cutting forests as trees. Its dangers is explained below.
Explanation:
Deforestation means cutting of trees or forest for some specific purposes. This can also include bush burning.
It has many adverse effect on our ecosystem and affect plants.
In one aspect, deforestation release carbon iv oxide into the atmosphere from burning of trees and bushes. Although, CO2 can be beneficial to plants for photosynthesis, its excess affects negatively.
Also, deforestation invariably speeds up the loss of nutrients into watercourses.
Furthermore, deforestation is an agent of global rise in temperature, also known as global warming l, which posed a threat our ecosystem and brings about destruction of plants. Forest protect the land from nutrients' depletion which is needed for healthy plants cultivation
It can be recommended that the dangers in deforestation supersedes its advantages, and thereby should be discouraged.

The Wilderness Society, the Sierra Club, the National Audubon Society, the Nature Conservancy, the National Wildlife Federation, and the National Parks and Conservation Association all predated the rise of modern ecological science. True or false?
Answer:
True
Explanation:
Final answer:
The statement is true; organizations like The Wilderness Society and others preceded the rise of modern ecological science. Initial conservation efforts in the 19th century, influenced by transcendentalist philosophy, led to the formation of organizations that later evolved with advances in ecological science.
Explanation:
The question pertains to the historical timeline of conservation organizations in relation to the development of modern ecological science. The statement suggests that organizations like The Wilderness Society, Sierra Club, National Audubon Society, The Nature Conservancy, National Wildlife Federation, and the National Parks and Conservation Association predate the rise of modern ecological science. This statement is true. Modern ecological science began to significantly influence conservation and resource management disciplines during the early 20th century. Yet many foundational conservation organizations were established during the 19th century when figures such as John Muir and George Perkins Marsh were already advocating for the protection of natural environments, long before the term "ecology" acquired its current scientific inference.
Conservation movements in the late 19th and early 20th centuries saw significant efforts towards preservation and utilitarian conservation, and involved pivotal figures like Gifford Pinchot and John Muir. Their efforts laid the groundwork for the establishment of the organizations mentioned above. The initial conservation movement was indeed influenced by transcendentalist philosophy and an early understanding of the impacts of human activity on the environment, which later evolved with the contributions of ecological science from the 20th century onwards.
Recall that one hour of right ascension is equal to 15 degrees. One minute of right ascension is equal to 0.25 degrees. During a full moon, the sun and the moon are 180 degrees apart from one another in the sky. How many hours of right ascension separate the sun and moon during a full moon?a) 180 hoursb) 24 hoursc) 12 hoursd) 165 hourse) 6 hoursf) 2 hoursg) 15 hours
Answer:
The right answer is option C
Explanation:
One hour of right ascension = 15 degrees
one minute of right ascension = 0.25 degrees
The sun and moon are 180 degrees apart.
We convert 180 degrees to hours by dividing by 15 degrees
180 / 15 = 12 hours
The right answer is option C
The principles of relative dating can be used to understand the order of geologic events. A geologic event can be anything: the deposition of horizontal layers of sedimentary rock, the faulting or folding of rock layers, the tilting of rock layers, the erosion (or wearing away) of rock, the intrusion of volcanic rock within existing rock layers, and so on.True / False.
Final answer:
The statement that principles of relative dating can determine the order of geologic events, such as sedimentary rock deposition or volcanic intrusion, is true. These principles are based on the law of superposition, original horizontality, and lateral continuity.
Explanation:
The statement is true. The principles of relative dating indeed utilize geological rules to deduce the chronological arrangement of geologic events. These events could include various processes such as the laying down of sedimentary rock layers, faulting or folding of these layers, intrusion of volcanic material, and more. Notable principles developed by Nicolas Steno include the law of superposition, which suggests that in undisturbed stratigraphic sequences, the oldest layers are at the bottom, while the youngest are on top.
Additionally, Steno's principle of original horizontality posits that sediment layers are initially deposited horizontally, meaning any subsequent tilting must have occurred after their formation. Furthermore, lateral continuity indicates that these layers of rock were continuous before being disturbed or interrupted by events such as the formation of a canyon. By applying these principles, geologists are able to reconstruct and correlate geological history without needing absolute dates, thus determining the relative ages of rock strata and the events that have shaped them.

Which mountain range runs down the western edge of south america and serves as the eastern border of chile?
Answer: The Andes
Explanation: The Andes is also called Andes Mountains, and it is a mountain system of South America that consist of a huge number of extremely high plateaus, which are surmounted by even higher peaks that form an unbroken ridge over a distance of some 5,500 miles. This ridge extends from the southern tip of South America to the continent’s northernmost coast on the Caribbean.
The _____ is the portion of Earth occupied by permanent human settlement. Humans are unevenly distributed across Earth as most of the world’s population is _____ in cities
Answer: Ecumene
Explanation:
Ecumene is a geographical term which means inhabited land. Ecumene refers to land where people have made their permanent home and a place where humans earn their living. Ecumene serves both residential and economics purpose to humans. Human beings carry out their day to day activities on ecumene.
* Humans are unevenly distributed across Earth as most of the world’s population lives in the cities. The larger percentage of the world's population now live in the city because of the presence of social amenities and the search for white collar job which causes overcrowding and increase in crime rate in the city.
Final answer:
The ecumene signifies Earth's regions inhabited permanently by humans, and a majority of the global population now lives in cities, illustrating significant uneven distribution. This urban concentration is especially prevalent in high-income countries and is driven by various factors including economic opportunities and urbanization trends. The challenge now is ensuring sustainable development amidst these shifts.
Explanation:
The ecumene is the portion of Earth occupied by permanent human settlement. Humans are unevenly distributed across Earth as most of the world’s population is concentrated in cities. This distribution is influenced by several factors including access to resources, historical migration patterns, and urbanization trends. Over time, the trend of urbanization has resulted in a significant shift in population from rural to urban areas. As of recent data, a majority of the global population now resides in urban areas, with the rate of urban dwellers increasing significantly over the past few decades. The shift towards urban living is more pronounced in high-income countries such as North America, Western Europe, and parts of Asia where up to 80% of the population lives in urban settings. Conversely, many low to lower-middle-income countries still have a significant proportion of their populations living in rural areas. Urbanization is closely linked to income levels, with wealthier nations experiencing higher rates of urbanization. Furthermore, cities offer a range of economic, social, and cultural opportunities that attract people from rural areas. However, this rapid urbanization also presents significant challenges, including the need for sustainable development to ensure that urban growth does not lead to excessive depletion or damage to the natural environment.

Make me thy lyre, even as the forest is: What if my leaves are falling like its own! The tumult of thy mighty harmonies Will take from both a deep, autumnal tone, Sweet though in sadness. Be thou, Spirit fierce, My spirit! Be thou me, impetuous one! Drive my dead thoughts over the universe Like withered leaves to quicken a new birth! And, by the incantation of this verse, Scatter, as from an unextinguished hearth Ashes and sparks, my words among mankind! Be through my lips to unawakened Earth The trumpet of a prophecy! O Wind, If Winter comes, can Spring be far behind?
Explanation: In these lines, the speaker—perhaps Shelley himself, as the speaker seems to be a poet or artist of some sort—seems to describe his ideas as stale or past their prime, like the withered leaves that fall from the trees in the season of autumn. Just as the west wind will drive those dead leaves away to make room for new life in the spring, the speaker seems to hope that the wind can, likewise, banish his dead thoughts in order to clear the space for new thoughts and new ideas. It is possible that the speaker is undergoing a sort of crisis of inspiration; he seems to feel that his old ideas are no longer fruitful, so to speak, and he longs for the "new birth" of original ideas and new inspiration. He hopes that the west wind can assist him with this.
Answer:
In all these phrases, the narrator— maybe Shelley himself, as the speaker could be some sort of a poet or artist — seems to characterize his ideas as outdated or past their best, like the wilted leaves which drop from the branches in the autumn term.
As the western breeze blows the fallen leaves away throughout the spring to make way for new life, the narrator seemed to assume that perhaps the breeze can also vanquish his dead worries and clear the room for new ideas and new thinking.
The speaker may be experiencing some form of inspiring crisis;
He seemed to believe like his old ways were no more, so as to speak, fruitful and longs for the "new birth" of original ideas and new inspiration.
He hopes the west wind will be able to help himself with all of that.

This passage is describing what type of government?
A) autocratic
B) democratic
C) dictatorship
D) oligarchic
From 1948 to 1994, South Africa existed under a system of apartheid. Under this system, white South Africans- about 18% of the population- controlled all of the instruments of government: the Parliament, the Executive Branch, and the courts. Black and non-white South Africans had few legal rights and could not vote in elections. Voting was limited to white South African citizens.
Answer:
TRUST ME IT'S B
Explanation:
Final answer:
The passage describes an apartheid government in South Africa, which was oligarchic, as a small white minority controlled the government and denied rights to the majority population.
Explanation:
The passage is describing an apartheid government, which is characterized by institutionalized racial segregation and discrimination. From 1948 to 1994, South Africa was under such a system where the minority white population, about 18% of the citizenry, controlled all instruments of government and denied the majority black and non-white South Africans basic legal rights and the ability to vote. The type of government most closely associated with the apartheid regime in South Africa would be an oligarchic government, option (D), since it refers to a form of power structure where a small group of people have control over a country. Even though it is similar to an autocratic government, where a single person has unlimited power, the control in apartheid South Africa was exercised by the white minority as a group, fitting better with the definition of an oligarchy.
Why is there no delta at the mouth of the hudson river?
Answer: There is no delta at the mouth of the Hudson River because it has a short history of erosion, which means it does not have a delta as there is no sediment to be deposited.
"There is no delta at the mouth of the Hudson River primarily due to the geological history and the characteristics of the river's flow.
The Hudson River flows into the Atlantic Ocean through a drowned river valley, which is a result of the sea level rise that occurred at the end of the last glacial period. As the glaciers retreated, the global sea level rose, and the increased water volume flooded the lower valley of the Hudson, creating a long and relatively narrow estuary. The formation of a delta typically requires a few key conditions that are not met by the Hudson River: 1. Sediment Load: Deltas form where a river carries a significant amount of sediment that it can no longer transport when it reaches the slower-moving or still waters of a lake or ocean. 2. Mouth Geography: The mouth of the Hudson is influenced by the strong tidal currents of the Atlantic Ocean. 3. Tidal Influence: The Hudson River estuary is subject to a significant tidal range, which means that the water level at the river's mouth rises and falls substantially with the tides. 4. Glacial History: The last glacial period scoured out the river valley, leaving behind a U-shaped trough that is now the Hudson River's path. As the ice retreated and sea levels rose, the estuary was formed without the conditions necessary for a delta to develop.A hominin (human family) skull was found in a shale layer between two fine-grained igneous rock layers. There were no baked zones on the rocks above the igneous layers. The skull had been 100% fossilized and changed to stone; there was no original skull material left. On the basis of this information, decide which of the following statements is true.
a. The skull should be dated by the carbon-14 method, since this is the method used for organic material older than 1 million years.
b. The igneous layers can be dated by radiometric methods; the shale layers cannot be dated radiometrically.
c. The skull itself cannot be dated, because it is no longer organic material and it is not igneous material. The age of the skull is determined by its position between the igneous layers.
d. The igneous layers must be lava flows, because they are fine-grained rock and there are no baked zones on the rock above them.
Answer:
a. The skull should be dated by the carbon-14 method, since this is the method used for organic material older than 1 million years.
Explanation:
The skull can be given an absolute age as it lies in a layer between the two sills. These igneous layers flow not the sills, as they have not baked by the sedimentary rocks that are found above and below them. The sedimentary rocks themselves cant be dated radio-metrically. Theses skull could be more than 100,000 years old as the genus of the homo has existed since then and now.The skull, now fossilized with no original organic material, can't be directly dated. The age is determined by dating the surrounding igneous rock layers.
Explanation:The correct statement is: "The skull itself cannot be dated, because it is no longer organic material and it is not igneous material. The age of the skull is determined by its position between the igneous layers." In geology, igneous layers can usually be radiometrically dated using the decay of radioactive isotopes. However, since the skull has been completely fossilized and there is no original organic material left, it cannot be dated using techniques like Carbon-14 dating. Therefore, the best estimation of the age of the fossil would be based on the dates established for the surrounding igneous layers.
