Science Pass Review

How does the ozone layer help life on Earth?

• It produces oxygen for the atmosphere.

• It protects Earth from meteors.

• It absorbs damaging ultraviolet radiation from the Sun.

• It reflects most of the Sun's radiation to keep the planet cool.

Ice samples from glaciers provide evidence that today's atmosphere contains more carbon dioxide than ancient atmospheres on Earth did. Why is this increase in carbon dioxide a concern to scientists?

• It contributes to the rapid expansion of continental glaciers.

• It contributes to the rapid cooling of the warm ocean currents.

• It contributes to the gradual warming of the atmosphere.

• It contributes to the loss of radiant energy from the Sun.

Why is deforestation a major problem in terms of its effect on global warming?

• Plants' root systems absorb many toxins from the soil which might contaminate the water supply.

• Plants remove significant amounts of carbon dioxide gas from the atmosphere through the process of photosynthesis.

• Plants remove significant amounts of nitrogen dioxide gas from the atmosphere through the process of denitrification.

• Plants' root systems hold the soil in place, and when they are gone, there is increased pollution from runoff.

As part of the water cycle, water from Earth’s surface enters the clouds and finally falls back to the ground in the form of rain. What is the correct sequence of processes water undergoes?

• evaporation → condensation → precipitation

• precipitation → condensation → evaporation

• condensation → evaporation → precipitation

• evaporation → precipitation → condensation

Which of the following best defines science?

• A collection of unchangeable facts about the natural world

• The study of the natural world through observation, identification, description, experimental investigation, and theoretical explanations

• A belief system based on assumptions about the natural world

• A method for proving theories beyond doubt

DOK Level 1: Recall

What is a common method for scientists to communicate their research findings?

• Through artistic performances

• By publishing in scientific journals

• By creating infomercials

• Through political debates

What is the role of evidence in modifying scientific theories?

• Evidence is rarely considered when modifying theories.

• Evidence can refute or support theories, leading to modifications.

• Theories are modified first, then evidence is found to support the changes.

• Evidence is only used to confirm existing theories, not modify them.

DOK Level 3: Strategic Thinking

What would most likely happen if all evaporation of water stopped?

• Runoff would increase.

• More clouds would form.

• No precipitation would fall.

• Moist air would be in the atmosphere.

A student examines the processes of evaporation and condensation in the water cycle by filling a beaker with water and covering the beaker with a glass lid. She positions a lamp so that its light shines on the beaker, as shown in the image.

The student finds that condensation did not significantly collect on the glass lid. What change should the student make in the design process to make her results more accurate?

• Remove the lid and leave the beaker open to the light from lamp.

• Remove the lid and cover the beaker with a dark cloth.

• Turn the lid over and place some ice cubes on it.

• Turn the lid over and pour some warm water on it.

The diagram shows various stages of the water cycle labeled P, Q, R, and S.

Which statement about the stages of the water cycle is correct?

• Stage P is evaporation, which occurs immediately after stage Q, which shows condensation.

• Stage Q is condensation, which occurs immediately after stage P, which shows evaporation.

• Stage R is evaporation, which occurs immediately before stage S, which shows precipitation.

• Stage Q is condensation, which occurs immediately before stage P, which shows precipitation.
