Weathering, Erosion, Deposition, and Soil

Madison creates the model shown of a stream bed. She wants to demonstrate how natural processes can change the surface of Earth through deposition and erosion. She pours water on her model and makes observations. In which situation will more deposition than erosion occur in Madison's stream bed model?

• More deposition will occur if the slope of the stream increases.

• More deposition will occur if sediment in the stream decreases.

• More deposition will occur if sediment in the stream increases.

• More deposition will occur if the speed of the stream water decreases.

Chase noticed after a heavy rainstorm that the loose dirt in his backyard had been moved around, creating channels and mounds. Select two of the processes that took place in Chase's backyard.

• compacting

• deposition

• sedimentation

• weathering

• erosion

How does erosion compare to physical weathering?

• Both break down materials.

• Erosion breaks down materials, and weathering carries them from place to place.

• Weathering breaks down materials, and erosion carries them from place to place.

• Both move materials from place to place.

Soil is a combination of rocks that have been weathered to small pieces and organic matter. Select two examples of chemical weathering that break up big rocks into smaller pieces for soil.

• acid rain causes cracks in large rocks

• wind blasts sand at bigger rocks

• a mole breaks up small rocks as it digs

• plant roots widen cracks in rocks

• a waterfall dissolves small pieces of mineral

Soil is made of many things, including tiny particles of rock. Which is one way rocks are broken down into rock particles?

• Molecules of water that are superheated inside of rocks can build up pressure that breaks rocks into rock particles.

• Radiation from sunlight creates tons of tiny cracks in the rock, which expand until they break.

• Molecules of water that freeze inside rocks can expand and break rocks into rock particles.

• Oxygen from the atmosphere gets absorbed by the rock, which expands until it breaks.

Based on the diagram, structure X is

• a delta that is changing due to sediment deposits from ocean currents.

• an island that is changing due to the movement of plate boundaries.

• a delta that is changing due to sediment deposits from a river.

• an island that is changing due to increasing volcanic lava flow.
