how tors are made

chemical and mechanical weathering breaks down the soft rock surrounding the granite. this leaves a tor behind.

carboniferous limetone

  • an example of a sedimentry rock
  • formed by the build up of wethered material
  • softer than granite
  • slowly disolves in rain water
  • found in uplands of englnd

limestone pavement

how a limestone pavement is formed.

rainwater mixes with chemicals such as carbon dioxide as it falls through the atmosphere. this creates a weak acid which reacts with sedimentary rock containing calcium carbonate such a limestone and chalk. over time many years this acid dissolves the rock.

clay and chalk

  • they are both sedimentary rock
  • they are formed by the build up of weathered material that is cmpacted together
  • both are relatively soft rock
  • clay is softer than chalk
  • both are permeable rock types
  • a scarp is a steep slope
  • a dip slope falls more gently
  • at the coastline it forms headlands and bays
  • nedals- in the isle of white

chalk escarpments

The chalk escarpment is the most distinctive feature of chalk scenery in England. It consists of two parts- the scarp slope, which is steep, and the dip slope, on which the land falls away more gently. The top of the escarpment has gently rolling hills with rounded summits. There is little surface drainage and rivers are few and far between; however, in places the dip slope has been cut by deep, steep-sided, V-shaped dry valleys, which are marked landscape features.
