Unit 6 Greenhouse Effect Checkpoint

The two greenhouse gases that have the greatest impact on climate change are (a)  

• Chlorofluorocarbons (CFCs)  and methane (CH4)

• Methane (CH4) and water vapor (H2O)

• Methane (CH4) and carbon dioxide (CO2)

Answer explanation

Methane (CH4) and carbon dioxide (CO2) are the two greenhouse gases with the greatest impact on climate change due to their significant contributions to the greenhouse effect and global warming.

According to the diagram, what can happen when solar energy hits clouds in Earth's atmosphere?

• it can be reflected or absorbed

• it can only be absorbed

• it can only be reflected

• it is neither reflected nor absorbed

Answer explanation

When solar energy hits clouds, it can either be reflected back into space or absorbed by the clouds. Therefore, the correct answer is that it can be reflected or absorbed.

Wave REVIEW: Which property of light is being demonstrated in this image?

• absorption

• diffraction

• reflection

• bending

Answer explanation

The image demonstrates reflection, which occurs when light bounces off a surface. This property is evident when we see clear images or light patterns, indicating that the light is being reflected rather than absorbed or diffracted.

Which are considered Greenhouse Gasses?

• Sodium Chloride, Sodium dioxide, methanicane, and other gases in the air are considered Greenhouse Gases

• Sodium Choride and smoky gasses

• Water vapor, carbon dioxide, methane, and other gases in the air

• Oxygen and Triglyceride

Answer explanation

The correct choice includes water vapor, carbon dioxide, and methane, which are well-known greenhouse gases that trap heat in the atmosphere, contributing to global warming. The other options do not contain recognized greenhouse gases.

The greenhouse effect.....

• Protects the ocean from excessive evaporation rates

• Is a place where people grow plants because the temperature is regulated

• Keeps Earth’s atmosphere at a temperature that is comfortable for most living things

Answer explanation

The greenhouse effect is crucial as it traps heat in Earth's atmosphere, maintaining a temperature that supports life. This is why the correct answer is that it keeps Earth’s atmosphere at a comfortable temperature for most living things.

Infrared Radiation that is not absorbed by Greenhouse Gases, land or clouds is reflected back ....

• to the Earth

• to space

• to the toposphere

• to the ocean

Answer explanation

Infrared radiation that is not absorbed by greenhouse gases, land, or clouds escapes back to space. This process helps regulate Earth's temperature by allowing excess heat to leave the atmosphere.

 Increased carbon dioxide may cause global warming by

• reducing the amount of oxygen in the air.

• allowing more sunlight into the atmosphere.

• trapping more heat in the atmosphere.

• reflecting more sunlight from clouds.

Answer explanation

Increased carbon dioxide traps more heat in the atmosphere, leading to global warming. This greenhouse effect prevents heat from escaping, causing temperatures to rise, unlike the other options which do not contribute to warming.

Which of the following atmospheric gasses are considered greenhouse gasses? Select ALL that apply.

• Water (H₂O)

• Carbon Dioxide (CO₂)

• Oxygen (O₂)

• Methane (CH₄)

• Nitrogen (N₂)

Answer explanation

Water (H2O), Carbon Dioxide (CO2), and Methane (CH4) are greenhouse gases as they trap heat in the atmosphere. Oxygen (O2) and Nitrogen (N2) do not have this property.

What do you notice when you get into a car that has been sitting in the Sun for a while?

• The car feels much warmer inside than it should, as heat is trapped inside by the windows.

• The car feels cooler than it should, as the sunlight doesn’t heat up metal.

• The car feels cooler inside than outside due to the shade from the car.

• The car stays the same temperature, regardless of the Sun.

Answer explanation

When a car sits in the Sun, the sunlight heats the interior, making it feel much warmer than expected. The windows trap this heat, preventing it from escaping, which is why the correct choice highlights this phenomenon.

What inference can be made about GHG and global temperature?

• As GHG increases, the average global temperature will continue to increase.

• The temperatures have risen and show no sign of decreasing.

• If GHG do not decline, the Earth will be too warm to support life.

• Global temperatures have risen substantially over the last 130 years.

Answer explanation

The correct choice indicates a direct relationship between GHG levels and global temperature. As greenhouse gases (GHG) increase, they trap more heat, leading to a rise in average global temperatures, supporting the inference made.
