Question

what do you understand by weathering, mass movement, rapid movement, land slides? (1/3 marks)​

Answer 1

Answer:

1. Weathering is the breaking down or dissolving of rocks and minerals on Earths surface. Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering.

2. Mass movement, also called Mass Wasting, bulk movements of soil and rock debris down slopes in response to the pull of gravity, or the rapid or gradual sinking of the Earth's ground surface in a predominantly vertical direction.

3. Rapid plant movement encompasses movement in plant structures occurring over a very short period, usually under one second. These rapid plant movements differ from the more common, but much slower "growth-movements" of plants, called tropisms.

4. A landslide is defined as the movement of a mass of rock, debris, or earth down a slope. Landslides are a type of "mass wasting," which denotes any down-slope movement of soil and rock under the direct influence of gravity. Earthquake shaking and other factors can also induce landslides underwater.
