Question 1

Which of the following processes is an example of endogenic geomorphic processes?

Accepted Answer

Endogenic forces are driven by energy originating from within the earth's interior. Diastrophism and volcanism are classic examples of endogenic processes, which build up relief features on the earth's surface.

Question 2

What do we call the process of breakdown of rocks at or near the earth's surface by ambient temperature, water, and air?

Accepted Answer

Weathering is the action of elements of weather and climate over earth materials. It involves the mechanical breakdown and chemical alteration of rocks in situ without much transport.

Question 3

Which of the following is a chemical weathering process?

Accepted Answer

Solution, carbonation, hydration, and oxidation are fundamental chemical weathering processes that decompose rocks through chemical reactions involving water and atmospheric gases.

Question 4

Movement of mass of rock, debris, or earth down a slope under the direct influence of gravity is called:

Accepted Answer

Mass wasting transfers rock debris down the slopes under the direct influence of gravity. Air, water, or ice do not carry these materials, unlike erosion.

Question 5

Which of the following is a rapid mass movement?

Accepted Answer

Landslides and earthflows are rapid movements of rock and soil down a steep slope, occurring suddenly and often triggered by heavy rainfall or earthquakes.
