review earth science

Bedrock that is closer to oceanic ridges is younger in age than bedrock that is farther away. What can best be concluded from this information?

• The shape of Earth’s lithosphere is continually changing.

• The movement of continental plates is caused by volcanic eruptions.

• The oceans are becoming deeper and warmer as more rocks are produced.

• The rocks on the ocean floor are producing tectonic plates that are converging.

Many houses are built on the sides of hills. Which of these actions would BEST prevent houses from sliding down hills after heavy rainfalls?

• increasing the slope of the hill

• spraying herbicides on the hil

• adding plants to the hill

• removing grass from the hill

Which of these is the BEST example of physical weathering?

• insects eating a dead tree

• a bulldozer pushing soil

• ice fracturing a stone

• acid rain dissolving limestone

• acid rain

• abrasion

• hydrolysis

• oxidation

Which analogy BEST illustrates why Earth’s plates move?

• A glass shatters as it falls from a table onto a tile floor.

• A tree root grows into a ledge and breaks off a piece of rock.

• Burning diesel fuel forces a piston downward, turning the crankshaft.

• A moving sidewalk transports travelers from one gate to another at an airport.

How does freezing water cause the weathering of rocks?  The freezing water—

• keeps the rocks in place
• makes the rocks last longer
• expands cracks and breaks rocks
• causes rocks to fall in landslides
