Physical And Human Processes Flashcards
Compare the weathering that is found in the uplands and lowlands
uplands: Corrie Pyramidal Peak Arête U-shaped valley
Compare the soil/rock movement processes in the uplands and lowlands
Plucking - the glacier pulls out chunks of rocks to leave a jagged surface. This provides material for abrasion.
Abrasion - rocks stuck in the ice grind away the bedrock under the glacier.
Freeze thaw - Freeze thaw weathering/frost shattering is a process of weathering that also occurs in upland areas. water in cracks in the rock freezes and expands forcing open the gap. When the ice melts more water can get into the crack and freeze again. After lots of freezing and thawing lumps of rock are broken off the surface. These small pieces of rock are called scree and often build up forming scree slopes on mountainsides
Compare misfit rivers and dry valleys
A misfit stream is a river that is either too large or too small to have eroded the valley or cave passage in which it flows. A dry valley may develop on many kinds of permeable rock, such as limestone and chalk, or sandy terrains that do not regularly sustain surface water flow. Such valleys do not hold surface water because it sinks into the permeable bedrock.
how glaciers have affected both landscapes
A glacier’s weight, combined with its gradual movement, can drastically reshape the landscape over hundreds or even thousands of years. The ice erodes the land surface and carries the broken rocks and soil debris far from their original places, resulting in some interesting glacial landforms.
ways humans have affected the Upland landscape
Sheep farming as sheep eat bushes and afforestation/deforestation
ways humans have affected the Lowland landscape
Growing vegetation and afforestation/deforestation
Compare which landscape (up/low) have been affected more by humans
Upland as sheep farming destroys bushes and all the green.
