उत्तर
Slope is a major factor in mass wasting because -
- Mass wasting is the down-slope movement of a loose mixture of soil, land, and rock particles by the force of gravity.
- In mass wasting the materials come down the slope without the aid of transporting medium like running water, ice, or wind.
- Mass wasting occurs continuously on all slopes.
- Some act very slowly, others very suddenly, often with disastrous results.
