Answer:
isostasy
Explanation:
Of iso, same; stasy, state; word derived from the Greek; its meaning speaks of the equilibrium state of the portions of the earth's crust and how they are permanently compensated. It is not a static equilibrium but a dynamic one, its behavior implies the recognition of erosion and sedimentation phenomena as exogenous factors and the rearrangement of cortical blocks as endogenous factors.
The earth's crust, having a lower density than the underlying layer (outer mantle), will submerge in it and float, in a measure proportional to the height, that is to say that the mountains will have deeper roots than the plains, the lowlands or the bottoms sailors
The theory has been widely known in some cases as "Plate Tectonics" and in others as "Continental Drift". Today, the first title conforms more to the scientific truth since the continents travel as passengers on the tectonic plates whose areal dimension is much greater.
The principle known as Isostasy describes how the lithosphere is in a state of gravitational equilibrium with the asthenosphere, letting the less dense continental material float over the denser mantle. The layer adjusts according to the additional or removed weight, seeking equilibrium.
Explanation:The principle you're referring to is known as Isostasy. This concept describes the state of gravitational equilibrium between the earth's lithosphere and asthenosphere (part of the upper mantle). It's a crucial principle in understanding the phenomenon of Earth's crust floating on the denser mantle.
Imagine a block of wood floating in water. The wood floats because it's less dense than water. Similarly, the less dense continental material floats on the denser mantle. This is the principle behind isostasy. When additional weight is added to the crust, such as from ice or sediment, it sinks further into the mantle until equilibrium is reestablished. When weight is removed, the crust rises again.

At the time of the Civil War, the settlements of Anglo southerners in Texas did not extend west much beyond this geographic feature, which separates the Coastal Plains and pine forest regions of the state from the middle and High Plains regions.
Answer:
The answer is the Balcones Escarpment.
Explanation:
The Balcones Escarpment is a geologic fault zone several miles wide that extends in an arc right across Texas from Del Rio to the Red River. In Del Rio it is about 1,000 feet high, and where it extends from San Antonio to Austin where it is about 300 feet high to Waco. It is the Balcones that creates the Hill Country in Texas, and that marks the beginning of the Edwards Plateau and the High Plains beyond. The rich and fertile prairie land that was the foundation of the cotton industry runs up to this escarpment but it acts like a wall. Above that on the plateau the ground is hard and craggy, marking a sharp distinction between farmers to the east on the fertile soils, and ranchers to the west but it was once a barrier for further settlement west.
Final answer:
The Gulf-Atlantic Coastal Plain separated the Coastal Plains and pine forest regions from the middle and High Plains regions in Texas during the Civil War.
Explanation:
The geographic feature that separates the Coastal Plains and pine forest regions of Texas from the middle and High Plains regions is the Gulf-Atlantic Coastal Plain. During the time of the Civil War, the settlements of Anglo southerners in Texas did not extend much beyond this feature. The Coastal Plains were dedicated to plantation agriculture using African slave labor.

Identify the true statement.
a. Strip mining can be done economically down to a depth of about 1 km.
b. Anthracite coal develops at depth along mountain belt borders, where temperatures reach 600°C.
c. Underground coal mining is dangerous because of possible tunnel collapse and possible methane gas explosions.
d. Coal began to form on the Earth soon afterlife evolved in the Precambrian.
Answer:
Option (C)
Explanation:
Coal is a sedimentary rock that forms due to the accumulation of dead matters of plants, trees, and converting it into coal over millions of years.
This coal is extracted from the earth in two ways-
Opencast mining- Here, in order to extract the coal, large strips of land are being excavated. Here, the construction of the tunnel is not required. It is comparatively safe and affects the environment in both long as well as short term. Underground mining- Here, the excavations and sub-surface tunnels are made in order to extract the required materials from a certain depth. This method is risky because the underground tunnels and the roof rocks can get the collapse and there may occur the methane gas explosion, and causes a fire, which is why it is not very safe to carry out underground mining.Thus, the correct answer is option (C)- which is true.
Antarctica receives more solar radiation than does any other place on Earth, yet the temperatures are so cold and the ice cap is reflective, so that little polar ice melts during the summer; otherwise, the water levels of the oceans would rise 250 feet and engulf most of the world’s great cities.
(A) is reflective, so that little polar ice melts during the summer; otherwise,
(B) is so reflective that little of the polar ice melts during the summer; were it to do so,
(C) so reflective that little polar ice melts during the summer, or else
(D) reflective, so that little of the polar ice melts during the summer, or
(E) reflects so that little of the polar ice melts during the summer; if it did
Answer:
Option (B)
Explanation:
From the given sentence, the use of the parallelism in the wording has to be taken in consideration. So, as -are so is used in the word -cold, likewise, the word -is so will also be used right before reflective. Then again, as the sentence continues, the phrase "-were it to do so" will provide the consequence of the melting of the ice, which is the first component of the sentence.
Thus, the correct answer is option (B).

According to the USDA, soil surveys show more than __% of natural topsails in North America has been lost since farming began in the U.S.
Answer:
30%
Explanation:
Every consecutive year the loss of topsoil becomes a serious issue for the farmer and policymaker. The reason behind the continuous loss of topsoil is when the upper layer of soil left fallow and exposed to heavy rains and winds. which takes the upper surface with them.
The practice like grazing of field and growing of crop on steeper slopes and continuous practice like crop rotation are the main reason behind the soil erosion.
As the country is moving toward the fast technology phase, practice of securing land to prevent it from erosion is lacking. The other reason behind the fast removal of topsoil is the use of modern technology to grow a crop.

A. managing waste B. conducting tests to monitor pollution C. formulating environmental regulations D. enforcing environmental regulations E. developing solutions for environmental problems
Answer:
One of the responsibilities of an environmental science and protection technician is Option B: Conducting tests to monitor pollution.
Explanation:
Environmental science and protection technicians are trained to help monitor the environment. They know a lot about the mechanics of testing for contamination and searching for the sources of pollution in the environment. These technicians often work as consultants or for government agencies or laboratory facilities that do a lot of environmental research. They are sometimes part of a wider team of scientists and researchers who ask the technicians to carry out specific tests on their behalf as part of the research. The environmental science and protection technician might also test for noncompliance with environmental regulations, but he or she is rarely expected to formulate those regulations or to enforce them.
Imagine you are a geologist charged with the task of choosing which sites listed below should get state-of-the-art volcano monitoring systems. Which of the volcanoes below is least in need of monitoring?
a. Mount Rainier, Washingtonb. Kauai, Hawaii
c. Kilauea, Hawaii
d. Mount Fuji/Fujiyama, Japan
Kauai in Hawaii, with its dormant volcanoes, is the least in need of advanced volcano monitoring systems compared to the actively threatening volcanoes Mount Rainier, Kilauea, and Mount Fuji.
Explanation:Among the volcanoes listed, Kauai in Hawaii is the least in need of a state-of-the-art volcano monitoring system. Kauai is home to dormant volcanoes that are not currently showing signs of activity. In contrast, Mount Rainier is an active stratovolcano with a significant risk of future eruptions, Kilauea is among the world’s most active volcanoes, and Mount Fuji in Japan is an active stratovolcano and also a significant risk due to its proximity to populated areas. Given that Kauai's volcanic threat is minimal compared to the others, it would be deemed the least in priority for state-of-the-art monitoring.
What type of rocks are formed by processes powered by the sun? A. metamorphic B. sedimentary C. igneous
The type of rocks that are formed by processes powered by the Sun are the sedimentary rocks.
Explanation:
There are three basic types of rocks on Earth, and all have their own specific way in which they form. The igneous rocks form under the influence of inside forces, or rather the rising magma from the mantle layer. The sedimentary rocks form under the influence of the outside forces, powered by the Sun. The metamorphic rocks form from preexisting rocks that have been influenced by inside force.
The sedimentary rocks, as mentioned, are formed by the influence of the outside forces which are powered by the Sun. The Sun powers the winds, temperatures, formation of ice, evaporation, precipitation etc. All these things have the ability to dissolve rocks, gradually creating sediments, which later manage to merge under certain temperature, pressure, and material that would act as natural glue for the sediments.

The types of rocks that are formed by processes powered by the sun are sedimentary rocks. These rocks are created when fragments of pre-existing rocks or organic materials, such as shells, are deposited by elements like wind or water and then cemented together over time without melting. Processes like weathering, erosion, and deposition, all driven by solar energy, contribute to the formation of sedimentary rocks. Therefore, among the options provided, the correct answer is B. sedimentary.
How did the Manchus, with a very small population in comparison to that of the Ming Dynasty, manage to conquer the great Chinese empire?
Answer:
They took advantage of the chaos and anarchy plaguing the country
Explanation:
The Manchus succeeded as the ruling dynasty when the last Ming emperor died after the destruction of yellow river which unleashed the flood that destroyed hundreds of thousands of people coupled with the break down of social order, wide spread of smallpox and two people taking control of separate parts of the country and declaring new dynasties.
Final answer:
The Manchus conquered the Ming Empire by exploiting the dynasty's internal turmoil and strategic mistakes. They effectively absorbed Chinese administrative practices and gained the support of many Chinese officials. This led to the Manchu capture of Beijing, the establishment of the Qing Dynasty, and subsequent rule over China for nearly three centuries.
Explanation:
The Manchus, a small but well-organized ethnic group, conquered the Ming Empire by capitalizing on the Ming Dynasty's internal weaknesses and strategic blunders. Despite their smaller population, the Manchus unified under strong military leaders and adopted Chinese administrative practices, increasing their appeal to Chinese officials. During the Ming dynasty's decline, faced with internal rebellions and high expenditures, many Chinese bureaucrats and military leaders defected to the Manchus due to the Ming Dynasty's corruption and incapability to tackle problems.
After the death of the Manchu leader Nurhaci, his son Hong Taiji took over and continued to expand control over Chinese territory. As the Ming dynasty's power waned, General Wu Sangui made the consequential decision to ally with the Manchus to fend off a peasant rebellion, allowing the Manchus through the Great Wall. This led to the capture of Beijing in 1644 and the establishment of the Qing Dynasty. The transition to full control took until 1683, but the Manchus were careful to maintain superior positions, requiring demonstrations of loyalty such as the Manchu hairstyle mandate.
The Qing Dynasty emphasized traditional Chinese philosophies and maintained strict control over trade and social order. Through adept governance, the Qing Dynasty marked a golden age in China's history, with population growth and contributions to Chinese literature. The Manchus managed to become the rulers of China by both military conquest and integrating into the existing social fabric, never completely eliminating Chinese culture but rather adapting and enforcing their rule within it.
The rate of plate movement is only a few ________ per year so climate changes triggered by shifting plates happen on a scale of millions of years.
Answer:
centimeters
Explanation:
The lithospheric plates move relative to the others at a very slow but continuous speed that is, on average, about five centimeters per year. This movement is ultimately driven by the unequal distribution of heat inside the Earth. The hot material found in the depths of the mantle moves slowly upwards and serves as a part of our planet's internal convection system. Simultaneously, colder and denser sheets of the oceanic lithosphere descend to the mantle, moving the rigid outer layer of the Earth into motion. Finally, the titanic friction between Earth's lithospheric plates generates earthquakes, creates volcanoes and deforms large masses of rock in the mountains. But it causes climate changes to be experienced every million years.

The technique called radiometric dating is based on
A) the formation of radioactive molecules in rocks after they are deposited.
B) the use of fossils of known age to determine how fast carbon-14 decays.
C) the assumption that radioactive isotopes accumulate in fossils at a constant rate.
D) the steady, clocklike decay of certain radioactive isotopes over time.
Answer:
D) the steady, clocklike decay of certain radioactive isotopes over time.
Explanation:
Geologists use radiometric dating to estimate how long ago rocks formed, and to infer the ages of fossils contained within those rocks.
For example, when rocks are formed, such as igneous rocks (formed when molten rocks cools), certain radioactive atoms are trapped inside the rocks during this formation process. Then these radioactive atoms decay over time.
The age of the rock can be estimated by comparing the occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant rate of decay.
From the options;
A) this is about the formation of the radioactive molecules and not about radiometric dating
B) this is radiocarbon dating (cabon dating/carbon-14 dating)
C) the assumption is wrong since the radioactive isotopes decays not accumulate.
D) the corect option as I explained earlier.

Biostratigraphy is the process of using "index fossils" to determine the age of a rock unit. An ideal index fossil comes from organisms that had_______________.
Answer:
Index fossils come from organisms that were distinct, widespread, abundant and short lived.
Index fossil, any animal or plant preserved in the rock record of the Earth that is characteristic of a particular span of geologic time or environment. A useful index fossil must be distinctive or easily recognizable, abundant, and have a wide geographic distribution and a short range through time. Index fossils are the basis for defining boundaries in the geologic time scale and for the correlation of strata. In marine strata, index fossils that are commonly used include the single-celled Protista with hard body parts and larger forms such as ammonoids. In terrestrial sediments of the Cenozoic Era, which began about 65.5 million years ago, mammals are widely used to date deposits. All of these animal forms have hard body parts, such as shells, bones, and teeth, and evolved rapidly.
Index fossil
The mechanism by which the atmosphere traps incoming shortwave radiation and outgoing longwave radiation and keeps it in the atmosphere near Earth's surface is called the _________.

In which of the following environments would you expect lithogenous sediment to be the dominant sediment type?
Answer: continental margins, muddy lagoons, sandy beaches, deep oceans.
Explanation:
Lithogenous sediments are sediments whose mineral grains are formed during the weathering of rocks, this sediments are transported by agents such as force of gravity, wind action, running water and movement of ice.
Lithogenous sediments are the most abundant sediments on the earth crust, example includes glacial marine sediments, abyssal clays etc. These sediments are composed of quartz, clay, and other rock fragments. They are found widely distributed along the continental margins, deep oceans, sandy beaches, muddy lagoons, etc.
Lithogenous or terrigenous sediments are derived from the weathering of continental rocks. As such, they dominate in areas close to land, including beaches, deltas, and nearshore areas. Factors like climate, current patterns, and bedrock type can influence their distribution.
Explanation:Lithogenous sediment, also known as terrigenous sediment, typically originates from the physical and chemical weathering of continental rocks. As such, you would expect to find lithogenous sediment as the dominant sediment type in locations close to land.
This includes, but is not limited to, beaches, deltas, and nearshore areas where rivers flow into the sea. Sediment carried by wind, such as in deserts, can also be classified as lithogenous. However, one must also note that the distribution of various sediment types in different environments is affected by factors like climate, current patterns, and the nature of the local bedrock.

Thanks for your question! Feel free to ask more!
Final answer:
The correct answer is 'A. pentatonic and tritonic'. The pentatonic scale is a five-note scale that is heavily used in traditional music, while tritonic scales with three notes are less common but still present in various music traditions.
Explanation:
Common scales used in African, Far Eastern, and Native American music are pentatonic and tritonic scales. The pentatonic scale is a five-note scale used widely in traditional music across various cultures. A common version of the major pentatonic scale is derived from the major scale but without the 4th or 7th pitches, while one of the popular minor pentatonic scales is similar to the minor scale but also omits these pitches. Tritonic scales, which use three pitches, are less common but also appear in some traditional musical contexts.
Instruments such as the Japanese koto and shakuhachi often utilize pentatonic scales. These scales enable musicians to create music that is beautiful and harmonious without the complexity of additional pitches found in heptatonic (seven-note) scales. The simplicity of the pentatonic scale can be seen in children's songs, early American folk music, and the blues, where the scale contributes to the music's distinct sound.
