Front

Which conclusion do Paula’s findings best support?
 Top layer: The lizards had thick tails that were about 1 inch in length.
 Middle layer: The lizards had round tails that were about 2 inches in length.
 Bottom layer: The lizards had flexible tails that were about 3 inches in length.

Back

Lizards in the area gradually developed shorter tails.

Front

How do plants contribute to the water cycle?

Back

Plants absorb groundwater and then release water into the atmosphere by the process of transpiration.

Front

What happens to water at the ocean’s surface as it moves from the equator toward the Arctic Ocean?

Back

The water cools, causing its density to increase.

Front

How can people be good stewards of water resources?

Back

by limiting nonessential usage of water

Front

How is geothermal energy classified?

Back

as a renewable resource, because geothermal energy cannot be depleted

Front

What relationship might exist between global climate change and permafrost?

Back

Increasing air temperatures will cause more permafrost to melt, and then more greenhouse gases will be released into the atmosphere.

Front

What benefit would there be in conserving the water people use in their homes during a drought in a community that uses a hydroelectric dam to generate electricity and has a reservoir that flows into a water treatment plant?

Back

Conserving water would increase the sustainability of the reservoir, increasing the amount of time the hydroelectric dam could be used as a source of electricity.

Front

Jody learns that water moving over the falls formed the cave. Which choice best explains how the cave formed?

Back

The moving water weathered the shale layer faster than the other layers, creating a cave.

Front

What evidence could show what type of rock Jody has found at the bottom of the falls? Options: the rock’s volume, the rock’s relative hardness, how far the rock is from Timber Falls, the amount of water stored in the rock

Back

the rock’s relative hardness

Front

What evidence could support Jody's claim that moving water at Timber Falls caused the shale layer to weather?

Back

Rock fragments containing silicon were discovered downstream of Timber Falls.
