Mass wasting occurs when. sediment moves to a lower elevation, while rock moves to a higher elevation sediment and rock moves from a lower elevation to a higher elevation sediment moves to a higher elevation, while rock moves to a lower elevation sediment and rock moves from a higher elevation to a lower elevation

sediment and rock moves from a higher elevation to a lower elevation

Explanation:

Mass wasting is said to be the downward movement of rock, soil, debris,sediments etc along a slope due to gravity. In other words theses particulate part of the earth is been move from a high elevation to a lower elevation due to the unstable nature of the slope.

Their are various event or factors that triggers Mass wasting which includes intense rainfall, volcanic eruption, human activities, earth quake shaking and storms. Intense rainfall can make the surface of a slope slippery thereby making it unstable and giving it room for smaller particles to easily slide downward.

Earth natural phenomenon like volcanic eruption and earth quakes disturbs the balance of the slope thereby resulting to the downward movement of soil, rocks ,debris and sediments.

explanation:

about 20% of the world's population lives in   southwest asia, but on less than 5% of the world's   land area.
