Changing UK landscapes
Sedimentary
-
-
Sandstone - sand sized grains cemented together. Can be hard and resistent to weathering but is permeable
-
-
-
-
-
Climate
high precipitation means there is a lot of surface drainage over the impermeable rocks - there are many streams
River Erosion
as rivers meander, they have eroded a wide valley between low hills. The rivers transport silt eroded from the river travel
River deposition
prolonged heavy rain can cause the rivers to flood. Water spreads out all over the valley floor, depositing the silt to form a wide, flat floodplain
Agriculture
-
Straight drainage ditches are not produced by natural physical processes so they are a good indication of human acitivty
Forestry
Many UK upland landscapes have been planted with trees for forestry. Sometimes in straight roads for easy management
-
Coastal Landscapes
Stormy weather
coasts are subject to strong winds increasing the eroding power of waves and heavy rainfall contributes to mass movement
-
-
-
-
Hard rock
-
Cliffs will be high, steep and rugged
includes wave cut platforms and headlands where caves, arches and stacks and formed
-
-
Industry
Increases air, noise and visual pollution
Can destroy habitats for birds, animals and sealife
-
-
-
Bays
Hard rocks are left jutting out, forming headlands
Soft rock is eroded more quickly, forming bays
Abrasion
breaking waves throw sand, pebbles and boulders against the coast during storms
-
-
Slumping occurs when rock is saturated, Loose, wet rocks slump down under the pull of gravity along curved slip planes
