Vocabulary	Vocabulary	Physical or Chemical Weathering?	Soil	Soil Erosion
100 Chemical Weathering the chemical breakdown and decomposition of rocks by natural processes in the environment	100 Glaciers Large sheets of flowing ice which shape the earth	100 Physical A pocket gopher burrows into the ground, placing soil on top	100 B Horizon This is the layer below the topsoil. Water carries material down to this layer making it a brownish reddish color.	100 deforestation, over plowing, not rotating crops, over-grazing Name one way humans are causing soil erosion
200 Physical Weathering the mechanical breakdown of rocks into smaller pieces that is caused by natural processes and that does not change the chemical composition of the rock material	200 Soil a loose mixture of rock fragments, organic material, water, and air that can support the growth of vegetation	200 Physical Water seeps into a rock, freezes, expands, and breaks the rock	200 A Horizon This contains the topsoil. Decomposers live in this horizon so it has the most decayed organic matter (humus)	200 crop rotation, planting trees and shrubs, terrace farming, move animals around Name one solution humans can do to help the problem of soil erosion
300 Weathering The breakdown of rock material by physical or chemical processes.	300 Humus dark, organic material formed in soil from decaying plant and animals	300 Chemical Chemicals in a rock react with oxygen causing oxidation	300 C Horizon This is the least-developed layer. This contains no organic matter and largest rocks.	300 the root systems hold the soil in place How do trees and shrubs help prevent soil erosion?
400 Erosion When water or wind moves sediments from one place to another	400 Soil profile a vertical section of soil that shows you all of the different layers.	400 Physical Plants grow into rocks and break rocks when their roots get bigger	400 A Horizon, B Horizon, C Horizon Name the 3 soil horizons	400 alternating between different crops every year so nutrients get back into soil. What does crop rotation mean?
500 Deposition the process by which material is laid down	500 Soil horizon each layer of soil within a soil profile	500 Chemical A factory pollutes the air which combines with the water in the atmosphere, causing acid rain	500 the oreo dirt cup lab What lab did we do to learn about the soil layers?	500 wind, water, gravity, glacier What other types of erosion is there besides human impact?
