UK Landscapes (Geology) : Distribution Flashcards
what rock type(s) are mostly found in upland areas?
igneous, metamorphic
what rock type(s) are mostly found in lowland areas?
sedimentary
why are igneous and metamorphic rocks found in upland areas?
because they are more resistant to weathering
why are the upland rocks more resistant to weathering
because of their crystals
why are sedimentary rocks found in lowland areas?
because they are more easily eroded / less resistant to weathering and erosion
how are crystals created?
created by force and heat when compacted
which rocks are eroded?
all rocks
how does the level of erosion differ from upland to lowland areas?
the resistance of rock in upland areas is higher than the resistance of rocks in lowland areas
what does the resistance of rock affect?
the speed of erosion and therefore changing the landscape
give example(s) of an upland area in the UK.
The Grampian Mountains, NW Highlands, Pennines
give an example of a lowland area in the UK
the Fens
what is special about the Pennines being an upland landscape?
they are made from hard limestone (sedimentary)
