  • A theory that considers the Earth to be a single, self-regulating system. (4, 10)
  • Deposits of dense minerals carried by water, e.g. tin and gold. (6, 7)
  • Materials or processes that involve material being carried by air or water then deposited. (11)
  • Processes or deposits associated with hot water. (12)
  • The average length of time that a molecule remains in a reservoir. (9, 4)
  • The characteristics of a soil based on the aggregation of soil particles into peds. (4, 9)
  • The characteristics of a soil based on the proportions of the mineral particles that are sand, silt and clay. (4, 7)
  • The lowest purity of ore that can be exploited economically. (3, 3, 5)
  • The natural nutrient enrichment of a water body. It can be accelerated by human actions such as the release of sewage effluent or the use of fertilisers that are leached into water bodies. (14)
  • The process by which surface water enters the ground between the particles of soil or rock. (12)
