Clues

  • In porous rocks such as chalk, tiny air spaces (pores) separate the mineral particles. The pores can absorb and store water. (7, 12)
  • 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)
  • 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 the decay of rocks involving chemical reactions between moisture and some minerals within the rock. (8, 10)
  • This is the in situ breakdown of rocks in tropical and sub-tropical deserts caused by extreme diurnal changes in surface temperature. Also called thermal expansion. (10, 10)
  • This is when the system undergoes self-regulation and changes its form in order to restore the equilibrium. (7, 11)
  • This is where changes in temperature and moisture cause rocks to break down into smaller particles. (10, 10)
