Question 20

a block material moves suddenly along a flat, inclined surface.

Answer 20

SLIDE

Question 21

mass movement of material containing a large amount of water which moves downslopes as a thick liquid

Answer 21

FLOW

Question 22

is a gradual process that occurs when the impact of water or wind detaches and removes soil particles, causing the soil to deteriorate.

Answer 22

SOIL EROSION

Question 23

when winds carry away vast quantity of fine soil particles and sand from deserts.

Answer 23

Wind Erosion

Question 24

when water moves as sheets taking away thin layers of soil.

Answer 24

Sheet Erosion

Question 25

the removal of surface material usually soil, by the action of running water. The processes create numerous tiny channels (rills) a few centimeter s in depth, most of which carry water only during storms.

Answer 25

Rill Erosion

Question 26

Happens when water moves as a channel down the slope and it scoops out the soil and forms gullies which gradually multiply and in the long run spread over a wide area.

Gully Erosion

Question 27

The land being dissected in gully erosion is called _____

Answer 27

bad lands or ravines
