Hydrosphere

Question 1

Drainage Basin

Answer 1

• Precipitation is the input
• Surface Run-Off
• Infiltration
• Percolation
• Throughflow and groundwater flow
• Surface storage
• Groundwater
• Evaporation
• Transpiration

Question 2

Waterfall

Answer 2

• Areas with bands of hard rock and soft rock
• Differential erosion
• Hydraulic action
• Abrasion
• Overhang turns into plunge pool
• Plunge pool deepens when erosion increases
• Overhang becomes unsupported and collapses
• Attration
• Waterfall reatreats forming a gorge

Question 3

V-Shaped Valley

Answer 3

• River erodes vertically
• Hyrdaulic action
• Abrasion
• Freeze thaw weathering
• Landslides
• Forms V-Shape and winds between interlocking spurs

Question 4

Meander

Answer 4

• Hydraulic action
• Abrasion
• Riffles and pools
• River flows faster on outside increases erosion
• Slower on inside so depostion occurs
• Helicodialflow
• River beaches and cliffs
• Meanders move downstream as erosion continues

Question 5

Ox-Bow Lake

Answer 5

• Meander erodes on outside due to fast flowing water
• Hydraulic action
• Abrasion
• Neck of meander gets narrower
• Heavy rain causes the river to breeach meander
• Forms new channel cutting off meander
• River in meander is slow so depostion occurs
• River takes easiest route
• The ox-bow may only be visible after heavy rain
