Paper 2 Flashcards
What are the three main Uk rock types?
Igneous
Sedimentary
Metamorphic
What are igneous tocks made from? (give an example)
Magma
Give two examples of igneous rocks.
- Basalt
- Granite
What are sedimentary rocks made out of?
Compressed sediments
Give two examples of sedimentary rocks.
- Clay
- Chalk
- Limestone
What are metamorphic rocks made out of?
Igneous or metamorphic rocks changed by heat or pressure
Name a type of metamorphic rocks.
- Slate
Give the characteristics/ properties of igneous rocks.
- Hard
- Resistant to erosion
[Granite landscapes are boggy and badly drained]
Give the characteristics/ properties of chalk and clay (sedimentary rocks).
Chalk:
- strong
- permeable
Clay:
- weak
- impermeable
[Caly landscapes are typically wide, flat plains]
Give the characteristics/ properties of metamorphic rocks.
- Very strong
- Resistant to erosion or weathering
How is the UK split geologically?
- The top half is mainly igneous and metamorphic, which forms UPLAND landscapes
- The bottom half is mainly sedimentary, which forms LOWLAND landscapes
What type I physical processes interact to produce upland and lowland landscapes? (give two)
- Climatological
- Post-glacial
- River
- Slope
Give three human activities that have heavily influenced the UK landscapes.
- Agriculture
- Forestry
- Settlements
