Write “POISON” on your Warm Up. Get out a piece of paper and a pencil. Number your paper from 1-21. Write your “Lucky Number” (1, 2, 3, 4, or 5) at the top of your paper.

POISON

Which of these are examples of constructive forces? frost action & abrasion volcanic action & deposition of sediment root pry & erosion exfoliation & faulting

Which is an example of a destructive force? root pry faulting folding deposition of sediment

Water chemically breaks down rock because water expands when it freezes. materials dissolved in the water are deposited someplace else. acids in the water react with substances in the rock. water is not affected by wind.

The removal of sediments and soil and depositing them someplace else is oxidation leaching. erosion. weathering.

A mushroom is an example of a structure in the hydrosphere. the geosphere. the atmosphere. the biosphere.

Beaches and sandbars are formed by wind. waves. glaciers. frost action.

The layer of rock beneath the soil is called bedrock. humus. topsoil. subsoil.

Products of weathering are called soil. lava. precipitation. sediments.

Which of the following could cause islands to form? exfoliation. volcanic eruption. precipitation. abrasion.

Which of the following is an everyday example of chemical weathering? Running water causes gullies to form in a farmer’s field. Ice forms in a crack in a rock and makes the crack larger. Weak acids in rain react with a limestone rock. A melting glacier creates a lake called a “tarn.”

Dr. Smith created this pie chart during a study of a loam soil in Kentucky. Based on the chart, which of the following is true? Loam contains more silt than sand. Only about 9% of loam’s composition is beneficial to plants. Over 50% of loam is made of clay. Most of loam is made of decayed organic matter.

Rainfall in a state changed from 50 inches a year to 10 inches a year Rainfall in a state changed from 50 inches a year to 10 inches a year. What would probably happen to the rate of chemical weathering? It would increase slightly. It would stay the same. It would double. It would decrease.

Weathered outer surface of the rock Unweathered inner surface of the rock The picture above shows the process of chemical weathering that can cause color changes in rocks in Kentucky. What is this process called? root pry oxidation faulting ice wedging

Frost action and exfoliation occur because water enters a crack in a rock. water expands when it freezes. carbon dioxide combines with water to form carbonic acid. water is a neutral substance.

Which of the following agents could cause BOTH chemical and physical weathering? living organisms wind humus gravity

What kind of chemical usually causes chemical weathering? base neutral carbon acid

What is the evidence that abrasion is a physical change of matter? gas is produced size & shape change energy is released state of matter changes

State the ESA for this scenario: The air temperature cools off and it rains. Rain falls on a slope causing a mudslide. B>H>G G>H>A A>H>G B>H>A

What kind of chemical is ALWAYS formed when an acid and base react? water salt neutral oxygen

What agent of erosion causes canyons to form? running water wind waves volcanic activity

Name a natural cause of acid rain. Moss volcanic eruption freezing water folding & faulting
