- Rocks
- limestone landscapes
- surface features
- swallow hole
- weathered holes on the surface that are sometimes entrances to caverns
- limestone pavement
- flat areas of limestone with grykes (cracks) and clints (raised areas)
- limestone gorge
- steep sided gorge formed when caverns collapse
- Resurgent river
- limestone is permeable so rivers can flow through it. When underground rivers hit impermeable rock they form a resurgence
- swallow hole
- underground features
- cavern
- form beneath swallow holes where the limestone has been deeply weathered
- pillar
- when stalactites and stalagmites grow so big that they meet in the middle
- limestone curtain
- formed from cacite dripping from the cavern roof
- stalactite
- formed from cacite dripping from the cavern roof
- stalagmite
- formed when calcite lands on cavern floors
- cavern
- surface features
- Granite landscapes
- tors
- moorland
- chalk and clay landscapes
- chalk escaprment
- chalk and clay lie diagonally on top of one another. Chalk is more resistant than clay, so clay is eroded faster leaving the chalk to stick out in hills
- clay vale
- chalk and clay lie diagonally on top of one another. Chalk is more resistant than clay, so clay is eroded faster leaving the chalk to stick out in hills
- dip slope
- scarp slope
- spring line
- clay is impermeable so when the water stored in chalk meets it, it springs up on to the surface
- aquifier
- chalk is permeable and stores water underground
- chalk escaprment
- limestone landscapes
