Weathering

Front 1

weathering

Back 1

mechanical or chemical surface processes that breaks rocks into smaller and smaller pieces

Front 2

mechanical weathering

Back 2

a physical processes that break rock apart without changing its chemical make up can be caused by ice wedging animals and plant roots

Front 3

ice wedging

Back 3

a mechanical weathering processes that occurs when water freezes in the cracks of rocks and expands causing the rock to break apart

Front 4

chemical weathering

Back 4

this occurs when chemical reactions dissolve the minerals in rocks or change them into different minerals

Front 5

oxidation

Back 5

chemical weathering processes that occurs when some minerals are exposed to oxygen and water over time

Front 6

Front 9

leaching

Back 9

the removal of minerals that have been dissolved in water

Front 10

counter farming

Back 10

planting along the natural counters of land to reduce soil erosion

Front 11

no-till farming

Back 11

a method for reducing soil erosion plant stalks are left in the field after harvesting and next years crops and planted within stalks without plowing

Front 12

terrancing

Back 12

farming method used to reduce erosion on steep slopes
