Answer:
B. Isostatic equilibrium
Explanation:
Isostasy is a state of balance or equilibrium between the lithospheric plate and the underlying mantle, the asthenosphere.
Due to the weight of the lithosphere, part of it sinks into the plastic asthenosphere and settles to an equilibrium position. This is what causes changes and differences in elevation on the earth.
As with all natural processes, the earth in itself tries to achieve stability and equilibrium in all it parts. The crust and a portion of the mantle forms the brittle lithosphere. The lithosphere floats on the plastic mantle. Due to density contrast, portions of the lithosphere tends to sink into the mantle from time to time. The lithosphere reaches a point where it no longer sinks and establishes an equilibrium with the asthenosphere.
This isostatic adjustment that occurs within the earth is responsible for the changes in elevations from places to places.
When portions of the crust gets eroded, it becomes lighter and rises up. When materials are deposited in adjacent areas or glaciers forms, they add increasing weight to the crust and causes it to further settle within the asthenosphere.
The correct answer is - Changes in land forms that affect large areas also affect living conditions.
The changes in the land forms, especially when it is on a large scale, affect the living conditions for most of the living organisms in that area, including the humans. The changes in the land forms can be caused by numerous things, be it heavy rainfalls, landslides, erosion, floods, earthquakes, volcanoes. They are all able to cause big damage and big changes in very short period of time, which changes the whole environment, thus changing the living conditions as well.
Explanation:
More than half of Earth's rain forests have already been lost due to the human demand for wood and arable land. Rain forests that once grew over 14 percent of the land on Earth now cover only about 6 percent.
Answer:
Lithosphere, hydrosphere and atmosphere make up the biosphere.
C.) Dividing
The Great Dividing Range, running just inland along Australia's eastern coast, is that continent's only significant mountain chain.
