weathering | The chemical, or mechanical process by witch rock is slowly broken down eventually becoming soil. |
mechanical weathering | The actual breaking up or physical eakening of rock by forces such as ice, or roots. |
chemical weathering | The process by which the actual chemical structure of the rock is changed, usually when water and co2 cause a breakdown of the rock |
acid rain | Rain whose high concentration of chemicals, usually from industrial polution, pollutes water, kills plant and animal life, and eats away at the, and eats away at the surface of atone and rock. |
erosion | the movement of weathered materials, including gravel soil and sand usually caused water wind and glaciers. |
sediment | particles of soil and rock carried and deposited and by water wind or ice. |
loess | fine grained mineral rich loam dust or silt deposited by wind. |
glacier | a huge slow moving mass of snow and ice. |
