Landscapes and physical processes Flashcards
Urbanisation (Flooding)
expansion of towns and cities
leads to ground being covered
Vegetation (Flooding)
different types intercept different amounts of rainfall
removal of vegetation
Geology (Flooding)
increased groundwater flow
a rock may not be porous
Climate (Flooding)
increased amounts of rainfall
seasonal rainfall
storm event
The speed at which water moves through drainage basins can vary due to:
quantity of rainfall
quantity of vegetation cover
size of drainage basin
Flows and stores of water
water moves through a drainage basin
flows from one store to another
Infiltration
movement of water into the soil
Intended human activity
management strategies
reduce erosion from river and coastal landforms
Extreme weather events (Climate)
a powerful storm can change the appearance of a storm overnight
More severe the storm, the more destructive the waves get
rivers (Climate)
more water that is flowing in the river, higher the erosion rates will be
Coasts (Climate)
the prevailing winds affects the angle at which the waves break on to the coastline
What factor affect the rates of landform change in river and coastal landscape
Geology
Climate
Human activity
Rock pools
are small hollows in rocks found at the coastline
Beaches and Spits
Both beaches and spits are formed when the swash is stronger than backwash
Arches and Stacks
weathering erodes the roof of the arch
the roof collapses to leave a pillar of rock
