• The amount of water used is higher when the human population is lower.

• The amount of water used is lowest when the human population is highest.

• The amount of water used is higher when the human population is higher.

The table shows typical temperatures in a gray wolf habitat. Which of these best describes a way that gray wolves adapt to survive the changing temperatures?

• Wolves develop a heavy coat in the fall and shed it in the spring.

• Each wolf's howl sounds different from the others

• A wolf pack works together to find food in the fall.

• Wolves are most active at sunrise and sunset.

The diagram shown is a model of the different layers inside Earth. Which two statements best compare the crust to the rest of the layers?

• The crust surrounds all the other layers and is solid.

• The crust is the innermost layer and is liquid.

• The crust is the thinnest layer and is solid.

• The crust is the outermost layer and is liquid.

• The crust is the thickest layer and is solid.

The diagram shows a V-shaped valley. The valley did not exist thousands of years ago. This valley is most likely the result of

• sediment being deposited by slow-moving water.

• riverbanks being eroded by fast-moving water.

• earthquakes causing the ground to split open.

• glaciers moving sediment to a new location.

A beaver is a mammal that builds its home in a stream or river. The beaver’s home is called a lodge. The beaver builds the lodge in the middle of a pond it creates by building dams in the stream. The picture shows a model of a stream ecosystem with two beaver dams and a beaver lodge. Based on the model, what would most likely happen to the ecosystem if the beavers and their dams were removed?

• The trees would have more water to use as the stream water moves more slowly through the ecosystem.

• The stream would be wider and deeper as the stream water moves more slowly through the ecosystem.

• The banks of the stream would have less erosion as the stream water moves more quickly through the ecosystem.

• The water used by plants on the banks of the stream would be reduced as the stream water moves more quickly through the ecosystem.

A student saw a rainbow outside after school. The next day the student decided to model how rainbows form. The student shines white light through a glass prism and sees how the light splits up into many colors. Which two ways does the student’s model need to be changed to better show how rainbows are formed?

• The prism should be as high in the air as rainbows are.

• The model needs to be outside because rainbows only form outside.

• The prism should have a round shape because raindrops are round.

• The prism should be made of water instead of glass because rain is made of water.

• Sunlight should be used instead of white light because sunlight and white light are made of different things.

On a forest field trip, a student is assigned a list of observations to make. One observation the student looks for is evidence of mechanical weathering. Which activity would allow the student to check mechanical weathering off the list?

• an acorn falling out of a tree

• an ant placing a soil particle on an anthill

• a puddle getting smaller as the sun shines on it

• a stone becoming smooth in a flowing riverbed

Many objects produce thermal energy. Students want to sort the objects into two groups: Group 1: Objects that use electricity to produce thermal energy. Group 2: Objects that use stored energy to produce thermal energy. Which question should the students ask to decide which object to put into Group 2?

• How much thermal energy does the object produce?

• How do people use the thermal energy produced by the object?

• Can the object produce thermal energy without being plugged in?

• Can the thermal energy produced by the object be changed into another form of energy?
