Clues
- chemical weathering of rocks creating new materials (13)
- Individual soil particles are pushed or heaved to the surface by wetting, heating or freezing of water. (4, 5, 4)
- is the unchannelled flow of water over a soil surface (9, 4)
- mechanical weathering of rocks resulting in smaller fragments of the same type (14)
- Small terraces from a few centimetres to 0.5m across the face of a slope caused by soil creep or solifluction (11, 4)
- this is the process where overlying rocks removed by erosion cause underlying ones to expand and fracture parallel to the surface. The removal of a great weight has the same effect (eg. glacier) (8, 7)
- this occurs in two main ways. First, in areas where temps fluctuate around 26-28 degrees c, sodium sulphate and sodium carbonate expand by 300%; Second, when water evaporates, salt crystals may be left behind to attack the structure (hot desert) (4, 7, 6)
- this occurs on rocks with calcium carbonate; eg. limestone, chalk. Rainfall and dissolved co2 forms a weak carbonic acid. calc.carb. reacts with acid & forms calc.bicarb. which is soluble & removed by percolating water (11, 8)
- This occurs when the soil's infiltration capacity is exceeded and can lead to the formation of gullies (7, 4, 4)
- water moving down through soil. (11, 4)
