Answer:
Landslide is a mass movement that involves rock and soil moving as a single unit.
Explanation:
Mass movement is every movement of a massive scale that occurs on the Earth's surface. There are several types of mass movements, such as creep, landslide, mudflow, and slump. They all have their own characteristics, mostly involving what causes the movement and what kind of material is moving.
The landslides are a type of mass movement that involves rock and soil moving as a single unit. This type of mass movement occurs because of the gravitational pull of Earth. This can not happen everywhere though, but only at places where the rock and soil and not very stable and are located at a steep slope. Over time, the weight of the rock and soil is too much for the bedrock to support it, so it slides down, causing an enormous amount of rock and soil to move in an instant and often to cause huge damage or loss of human lives.
