Loading flashcards...
1

Avalanches

Rapid movements of snow, ice, rock or earth down a slope

2

Climatic geomorphology

Different processes that operate in different climatic zones, producing different slope forms or shapes.

3

Falls

Movements of rock/debris under the effect of gravity.

4

Flows

Movement of a mass of soil or rock that contain a significant amount of water.

5

Heaves

Movements of soil or ice towards the surface in a vertical direction

6

Mass movements

Large scale movements of the Earth's surface that are not accompanied by a moving agent such as a river, glacier or ocean wave.

7

Regolith

Irregular cover of loose rock debris that covers the Earth.

8

Shear Strength

Internal resistance of a slope

9

Shear stress

Forces attempting to pull a mass downslope.

10

Sheet wash

Unchannelled flow of water over a soil surface.

11

Sides

An entire mass of material moving along a slip plane

12

Slope

Inclines surface (hillslope) or an angle of inclination (slope angle)

13

Slope evolution

Development of slopes over time

14

Slope form

Shape of the slope in cross-section

15

Slope processes

Activities acting on the slope

16

Slumps

Form of mass movement which occur on weaker rocks, especially day, and have a rotational movement along a curved slip plane.

17

Throughflow

Water moving down through the soil.

18

Climatic geomorphology

Branch of geography that studies how different processes operate in different climatic zones.

19

Soil

Part of the regolith. It is structure and texture and determines how much

20

Surface wash

Soil's infiltration capacity is exceeded

21

Sheetwash

Us channelled flow of water over a soil surface

22

Soil heave or creep

Slow, small scale process which occurs mainly in winter. Happens due to moisture and volume change. Form terracettes.
