Detailed explanation-1: -Landslides occur when masses of rock, earth, or debris move down a slope. They may be very small or very large, and can move at slow to very high speeds. However, slow movement is also seen in the gradual downhill creep of soil on gently sloping land.

Detailed explanation-2: -A mudflow, also known as mudslide or mud flow, is a form of mass wasting involving fast-moving flow of debris and dirt that has become liquified by the addition of water. Such flows can move at speeds ranging from 3 meters/minute to 5 meters/second.

Detailed explanation-3: -Creep is the slowest and the least noticeable type of mass movement or wasting. Creep involves the entire hillside and in it rock or soil material moves over a period of several years.

Detailed explanation-4: -Surface creep is the slow downhill movement of soil and rock debris.

Detailed explanation-5: -The slowest and least noticeable, but most widespread of the slow mass wasting categories is creep. Creep involves the entire hillside, and is characterized by very slow movement of soil or rock material over a period of several years.
