How do plants contribute to the water cycle?

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

How can people be good stewards of water resources?

How is geothermal energy classified?

How are viruses similar to parasites?

The food web below represents the interactions of organisms P through U.

Select the two food sources for organism U.

Which choice describes a biotic factor in an ecosystem?

Timber Falls

Which situation is most likely to prevent a viral epidemic from becoming a pandemic?

The diagram below shows a food web for a forest ecosystem.

A scientist introduces a population of wolves into this ecosystem. The wolves have been observed to only prey on deer. What effect would the introduction of wolves have on this ecosystem?

Which information can best help scientists determine if two different organisms are members of the same species?

A student pours a cloudy liquid through a thin piece of paper and into a beaker. The student observes the collected liquid is not cloudy. How should the student classify the original cloudy liquid?

Wendy draws this model to represent a neutral beryllium (Be) atom.

Wendy’s teacher says there is an error in her model. What is the error?

How are the properties of helium (He) and krypton (Kr) similar?

A scientist experiments on a piece of solid copper.
The scientist heats the copper piece and observes the copper’s density decreases as its temperature increases.
The scientist continues to heat the copper until it melts.
How are the decrease in density and the melting similar?

Jonathan lives in a town near an estuary. The estuary is a part of the Windy River basin. The table below shows average and 2018 monthly rainfall amounts from June to September for Jonathan’s town.

Select two claims supported by this scenario.

Calm Lake Investigation

A person has recently started riding a bike to work instead of driving a gasoline-powered car. How will this action affect the availability of fossil fuels?

The diagram below represents a region's food chain.

plants - squirrel → coyote

Which change would increase the amount of carbon available to coyotes?

Methane is a pure substance and exists as a gas at room temperature. Each methane molecule is made up of one carbon atom chemically bonded to four hydrogen atoms. How is methane classified?

An unidentified pure solid is composed of an element. The substance is metallic and reacts vigorously when placed in water. Where is this element most likely found on the periodic table?

Suppose a large coal reserve is discovered on a mountaintop. The coal is extracted using a strip mine, where
the topsoil is removed by large trucks and
rocks are cleared by blasting with dynamite.
A town exists at the foot of the mountain.

How will this strip mine affect the environment?

Olivia finds two dinosaur fossils in a museum:
Apatosaurus fossil: 150 million years old
Diplodocus fossil: 154 million years old
What evidence would show these organisms share a common ancestor?

Timber Falls

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

Jody notices a fossil of a dinosaur, Stegosaurus, discovered in the dolostone layer of Timber Falls. What can Jody conclude about when Dalmanites and Stegosaurus lived?

Jody finds a rock at the bottom of the falls. She suspects that this rock originated from the rock layers at Timber Falls. What evidence could show what type of rock she has found?

Jody claims that moving water at Timber Falls caused the shale layer to weather. What evidence could be used to support her claim?

Select two factors that explain why limestone weathers faster than dolostone:

Calm Lake Investigation

Xavier learns that aquatic bacteria decrease the lake's dissolved oxygen content as they grow and reproduce. How could Xavier revise Figure 1 to better represent an effect of an increase in aquatic bacteria?

Under normal conditions, how do the algae in Calm Lake contribute to the cycling of matter?

Which choice best describes the amount of nutrient pollution in Calm Lake from Day 25 to Day 30?

Use Figure 2 and Figure 3 to answer this question:

What does the change from Day 9 to Day 10 indicate?

A fish population lives in Calm Lake. The lake water is considered unsafe for these fish if the dissolved oxygen content drops below 6 milligrams per liter of water. What does Figure 3 show about the safety of Calm Lake for these fish?
