Clues

  • Processes to do with movement on the land. (10, 9)
  • Solutions of salt can seep into the pore spaces in porous rocks. Here the salts precipitate, forming crystals. The growth of these crystals creates stress in the rock causing it to disintegrate. (4, 15)
  • The chemical weathering process by which rock minerals are dissolved. (8, 10)
  • The process by which an initial change in a system is amplified and causes further change. (8, 8)
  • The process of self-regulation which restores equilibrium to a system. (8, 8)
  • This involves dissolving minerals like carbonates in coastal rock. However, as the pH of sea water is invariably around 7 or 8, this process is usually of limited significance unless the water is locally polluted & acidic; still needs lots of materia (8, 7)
  • This is a mechanical weathering process caused by water, confined in rock joints, expanding as it freezes, and as a result breaking rocks into smaller particles. (6, 4, 10)
  • This is when the system undergoes self-regulation and changes its form in order to restore the equilibrium. (7, 11)
  • This occurs when waves break against a cliff face, and air and water trapped in cracks and crevices become compressed. As the wave recedes the pressure is released, the air and water suddenly expands and the crack is widened. (9, 6)
  • When overlying rocks are removed by weathering and erosion, the underlying rock expands and fractures parallel to the surface. The parallel fractures are sometimes called pseudo-bedding planes. (8, 7)
