Upland Granite

Locations-

North Scotland,Ireland and South West England.

Landscape Formation-

  • Batholith = cooled granite
  • rock shrinks as it cools creating vertical cracks
  • Where the cracks are close they erode faster
  • Ice/rivers remove the surface, exposing the Granite tor
  • Pressure release as the rock expands and creates horizontal cracks

Characteristics-

Horizontal and vertical cracks; tors; enlarged joints; rounded edges; cutter slopes and broken rocks
