Explanation:

- Creep:

- Creep is a slow mass movement.

- It involves the gradual downhill movement of soil and rock.

- It occurs so slowly that it is often difficult to notice at first.

- Earthflow:

- This is a faster movement compared to creep.

- It involves the flow of soil and debris, typically after heavy rain.

- Mudflow:

- Mudflows are rapid movements.

- They consist of water, soil, and debris and often occur after intense rainfall.

- Landslide:

- Landslides are fast movements.

- They involve a large mass of earth or rock moving quickly down a slope.
