Answer 4

• concept that diff climate zones produce a distinct set of geomorphological processes, which produce distinct geomorphological features

Question 5

Slope form

Answer 5

• aka slope shape

Question 6

Avalanches

Answer 10

• mass movements consisting of v. fast flows of snow, ice + debris

Question 11

Slope processes

Answer 11

• physical processes (e.g. landslides, overland flow, soil creep) that operate on a slope

Question 12

Slides

Answer 12

• entire mass of material moving along a slip plane

Question 13

Slump

Answer 13

• form of mass movement occurring on weaker rocks, esp. clay, + have rotational movement along a curve slip plane

Question 14

Throughflow

Answer 14

• water moving down soil

Question 15

Waste

Answer 17

• slow movement of fragments on a scree slope

Question 18

Rotational slide

Answer 18

• type of rockslide where sliding material follows a slip plane, + produces several steps or terraces

Question 19

Hazard assessment

Answer 19

• process of determining
  
  • when + where hazards have occurred in past
  • severity of physical effects of past events of a given magnitude
  • frequency of events strong enough to generate physical effects
  • what a particular event would be like if it were to occur now

Question 20

Falls

Answer 20

• mass movements occurring on steep slopes. esp. on bare rock faces where joints are exposed

Question 21

Surface wash/overland flow

Answer 21

• flowing of water over Earth’s surface once exceeds infiltration capacity
