What landscapes are there in the Uk & what factors affect the relief of the land?
Rock type & formation
Igneous
Andesite, basalt and pumice (extrusive)
Forms when magma from within the earth is pulled to the surface then solidified.
Volcanic lava - basalt platforms - Giants causeway - n. Ireland
Granite (intrusive)
Batholith
Sedimentary
Limestone, chalk, sandstone
Old Harry
Metamorphic
Tees-Exe line
Older rocks - upland - NE of tees-exe line
Younger rocks - East of tees-exe line
Processes changing landscape over time
Erosion
Tectonic movements - continental drift
Weathering
freeze thaw weathering - forms scree
breaking down of rock by weather and plants
physical, chemical, biological
Rivers - v shaped valley
glaciers - u shaped valley
physical processes in upland areas
landscapes
Limestone cliffs/ pavements
Highland/ upland areas like hills
Lowland plains
Glaciers - glaciation - glacialed landscapes
Physical processes in lowland areas
