Weathering and Soil Review Game What do you call rain combined with pollutants? Acid Rain What do you call a rock that contains tiny, connected spaces through which water can move? Permeable What does humus do to soil? Makes it fertile What two factors determine the rate of weathering? Type of rock and climate What kind of weathering is caused by the actions of animals? Mechanical weathering What do you call the series of processes that slowly change rocks from one kind to another? Rock Cycle What agent of chemical weathering combines with water to form carbonic acid? Carbon dioxide A mineral must be formed by natural or manufactured processes to be considered a mineral? natural Does chemical weathering change the chemical makeup of the weathered rocks? yes Weathering due to a release of pressure is called what? Mechanical weathering Where is the rate of chemical weathering the fastest – in hot, wet climates or cold, dry climates? Hot, wet climates What do you call the loose layer of leaves on the surface of the soil? litter How long did it take for the thick, fertile soil of North American prairies to develop? Thousands of years What can cause the loss of soil that is not protected by plant cover? Erosion by water or wind What effect did plowing the grass into the soil have on the Great Plains during the 1930s? Helped cause the Dust Bowl What term describes the management of soil to prevent its destruction? Soil conservation What do you call the practice of plowing fields along the curves of a slope? Contour plowing In conservation plowing why do they leave dead weeds and such on the ground? To retain moisture and hold the soil in one place What do living organisms in soil help with? Mixing the soil and make up humus What do you call the organisms that break down and digest the remains of dead organisms? Decomposers Who does most of the work mixing humus with soil? earthworms Why is soil a valuable resource? It is important to all living things on land What kind of weathering causes the mineral composition of rocks to change? Chemical weathering When a rock with iron becomes soft and crumbly, and reddish brown what has probably occurred? Exposed to oxygen Why does permeable rock weather easily? It contains many small connected airspaces What do Earthworms contribute to the soil when they excrete waste and leave behind their dead bodies ? humus What do you call the geological principle that operates today as well as in the past? Uniformitarianism What do you call the agent of mechanical weathering that grinds rock particles together? abrasion What two things occur that cause ice wedging? Freezing and thawing What kind of rock cools magma below the surface or lava at the surface of the earth? igneous What do you call a hard colorful mineral that is brilliant or has a glossy luster? gemstone What do you call a repeating pattern of mineral’s particles? crystal Why are brick, steel, and glass made from substances in the earth but not classified as minerals? They are not naturally occurring
