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.

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.

Most causes of speciation are relatively slow, in that the differences separating species take many generations to accrue and establish reproductive isolation. Which of the following is most likely to produce a species in just a few generations?
a. Genetic drift
b. Behavioral isolation
c. Reinforcement
d. Founder effect
e. Polyploidy

Answers

Answer:

Genetic drift produces a species in just a few generation.

Explanation:

Genetic drift means change in the gene frequency in a population due to random sampling of an organism.The allele of the sample in the parents has a role that determines the survival and reproduction of the organism.Allele frequency is the copy of gene which shares a particular form.Thus those speciation which occur due to genetic drift will produce species in just few generations.

The effect of genetic drift is larger and is acting on neutral mutation.

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.

Answers

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.

_____________

X= 2
Final answer:

In the given equation 6x + 13 = 16x - 7, you solve for 'x' through algebra to find that 'x' is equal to '2'.

Explanation:

We'll start by using algebra to solve this equation. First, let's isolate the variable x by bringing the terms with x together.

Subtract 6x from both sides of the equation: 6x - 6x + 13 = 16x - 6x -7. This simplifies to 13 = 10x - 7.Next, add 7 to both sides of the equation to further isolate the x term: 13 + 7 = 10x. This simplifies to 20 = 10x.Lastly, divide both sides of the equation by 10 to solve for x: x = 20/10. This gives us the answer that x = 2.

Therefore, if 6x + 13 = 16x - 7, then x is equal to 2.

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

Answers

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.

What is the major source of heat for contact metamorphism? What is the major source of heat for contact metamorphism? heat from a nearby magma body deep burial and heat from the Earth's interior heat from the spontaneous decomposition of micas and feldspars heat from grinding and shearing on faults

Answers

Answer:

heat from a nearby magma body,

Explanation:

The contact metamorphism occurs alongside the igneous intrusion and results form the high temperatures and since only a small area surrounded the intrusion and the metamorphism is limited to the surrounding zones. The major source of the heat for the contact metamorphism is the magmas and the temperature for the contact metamorphism varies about 400-1000°C.
Final answer:

The major source of heat for contact metamorphism is heat from a nearby magma body. It occurs when rocks are heated to high temperatures by the nearby magma from Earth's mantle or crust, resulting in metamorphic rock. This is different from regional metamorphism, which is caused by pressures and temperatures from tectonic activity.

Explanation:

The major source of heat for contact metamorphism is heat from a nearby magma body. Contact metamorphism occurs when rocks are heated to high temperatures by nearby molten rock or magma from the Earth's mantle or crust. Rocks adjacent to the magma are altered by the high heat, resulting in metamorphic rock.

Contact metamorphism is caused by a rise in temperature within the host rock when it comes into contact with magma. This is why the phenomenon is commonly observed near areas with volcanic activity, where heat from magma alters the structure and composition of rocks.

It's important to note that contact metamorphism differs from regional metamorphism, which is metamorphism that occurs over large areas and is typically due to the immense pressures and temperatures associated with tectonic activity, rather than direct heat from magma.

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.

What is the difference between the lithosphere and asthenosphere? At what depth does the lithosphere- asthenosphere boundary occur? Is this above or below the Moho? Is the asthenosphere entirely liquid?

Answers

Explanation:

Difference Between the lithosphere and asthenosphere:

Lithosphere is a solid outermost shell of the earth planet and composed of three layers o crust, mantle and core. The viscous and ductile region that lies under the lithosphere is called asthenosphere. So the difference between both of these layers is

" Lithosphere is a solid layer as it composed of rigid materials and the temperature is relatively cool then that of asthenosphere. Asthenosphere composed of viscous melted material and this region has high temperature and pressure."

Depth of lithosphere & asthenosphere boundaries:

The boundary of lithosphere and asthenosphere lies at the depth of about 100 to 150 km.

Above or below the Moho:

Moho lies at the depth of about 35 Km so the boundary of lithosphere and asthenosphere lies below the Moho.

Is the asthenosphere entirely liquid :

Although asthenosphere has a flowing ability but we can not say that its a liquid. Asthenosphere is composed of melted rocks so it lies in the category of solid. Its a viscous melted material. Its not entirely a liquid.

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?

Answers

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.

Imagine that Earth were in a stable orbit at its current distance from the Sun, but around a different star that had twice the mass of the Sun. Which of the following would have to be true?A. Earth's year would be shorter.B. Earth's year would be longer.C. Earth's mass would be lower.D. Earth's mass would be higher.

Answers

Answer:

A) Earth's year would be shorter.

Explanation:

If the earth were in a stable orbit at its current distance from the Sun, but around a different star that had twice the mass of the sun the earth's year would be shorter because it would take earth less time to revolve around its orbit.

Final answer:

If Earth orbited a star with twice the mass of the Sun at the same distance, Earth's year would be shorter due to Kepler's third law.

Explanation:

If Earth were in a stable orbit at its current distance from the Sun, but around a different star with twice the mass of the Sun, then according to Kepler's third law (the law of harmonies), Earth's year would be shorter. The period of the orbit (the length of a year) is proportional to the square root of the cube of the semi-major axis of the orbit (the average distance from the star), divided by the square root of the mass of the star. So, if the mass of the star is increased, the denominator of this relationship increases, and thus the overall value of the period decreases. This means that the Earth would complete its orbit in a shorter amount of time, hence a shorter year.

Some commentators have suggested that a heightened sense of patriotism may increase military enlistments, while others think that the existence of actual hostilities may deter young people from choosing a military path. A polling organization wants to investigate what this years high school seniors are planning to do after they graduate.1) During the 90s about 63% of high school graduates enrolled in college. The pollsters hope to estimate the percentage of this years seniors planning to attend college with a margin of error no greater than 4%. What size sample would suffice if they want to have 90% confidence in the estimate?The pollsters randomly select 5 cities in Upstate New York and then randomly selected on high school in each city. The guidance office at each of the chosen schools is instructed to ask 100 randomly selected seniors what their current plans are, and to report the results back to the pollsters. The data collected from the 5 schools are summarized in the following table.PlansCountCollege289Employment112Military26Other (travel, parenting, etc.)51Undecided / No response222) Determine a 90% confidence interval for the percentage of seniors planning to go to college this year. Explain in context what your interval means. Make sure you include your checks that the conditions for inference have been met.3) During the 90s about 4.5% of high school seniors enlisted in the military. Do these data suggest that the percentage who enlist is different this year? Test an appropriate hypothesis and state your conclusion. Make sure you state your null and alternative hypothesis, the test statistic, the P-value, your alpha level, and your conclusion.4) A few of the seniors did not respond to the guidance queries, and others said they were undecided. Some of the people might eventually decide to enlist in the military. Suppose that half of this small group also enlist. Would that cause you to change your conclusion in Question 3? Make sure you perform another hypothesis test and make sure you state your null, alternative hypothesis, the test statistic, the P-value, your alpha level, and your conclusion.
