Pass Science Review

Which gas of the Earth's atmosphere is classified as a greenhouse gas?

• Argon

• Carbon Dioxide

• Nitrogen

• Oxygen

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.

Where does the greatest atmospheric pressure occur?

• Mesosphere

• Stratosphere

• Thermosphere

• Troposphere

Air pressure changes across the different layers of the atmosphere. Which option sequences the atmosphere's layers in increasing order of atmospheric pressure?

• troposphere, stratosphere, mesosphere, thermosphere, exosphere

• troposphere, stratosphere, thermosphere, mesosphere, exosphere

• exosphere, mesosphere, thermosphere, stratosphere, troposphere

• exosphere, thermosphere, mesosphere, stratosphere, troposphere

What are the two most common gases found throughout the atmospheric layers?

• carbon dioxide and oxygen

• ozone and water vapor

• nitrogen and oxygen

• carbon dioxide and nitrogen

A student stacks five different textbooks to represent a model of the major layers of the atmosphere, as shown.

If the physics textbook represents the lowest layer of the atmosphere, which statement is true?

• The ozone layer is contained in the layer represented by the literature textbook.

• The layer closest to outer space is represented by the mathematics textbook.

• All weather activities occur in the layer represented by the history textbook.

• The warmest layer of the atmosphere is represented by the biology textbook.

The graph shows the temperature of the different layers of Earth’s atmosphere.

What can be a valid interpretation of the data?

• The temperature in the Thermosphere decreases with increasing altitude.

• The Stratosphere is the warmest layer except in its upper region.

• The Mesosphere is the warmest layer of Earth’s atmosphere.

• The temperature in the Troposphere increases with decreasing altitude.

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.

In order to reduce the possible impacts of global warming, scientists state that humans need to produce fewer greenhouse gases. Which statement describes a method that will reduce greenhouse gas output the most?

• Use energy efficient appliances.

• Recycle paper and plastic.

• Burn natural gas instead of coal to produce electricity.

• Use solar and wind power to produce electricity.
