ENVS LT 8.1 Global Warming Review

What is the Greenhouse Effect?

• Sunlight passes through the atmosphere and warms the Earth’s surface.

• The heat hits the Earth and then is radiated back toward space.

• The greenhouse gas molecules in the atmosphere absorb most of the heat and then send the heat in all directions.

• All of the above.

Which of the following are human activities that contribute to the increase in greenhouse gases?

• Planting trees and recycling

• Burning fossil fuels and deforestation

• Using solar panels and wind energy

• Water conservation and composting

Deforestation contributes to global warming by:

• Increasing the amount of carbon dioxide in the atmosphere

• Decreasing the amount of sunlight reaching the earth

• Reducing the greenhouse effect

• Increasing rainfall

What role do plants play in the greenhouse effect?

• They release carbon dioxide which increases the greenhouse effect.

• They absorb carbon dioxide, thus reducing the greenhouse effect.

• They emit methane, which has no effect on the greenhouse effect.

• They reflect sunlight, increasing Earth's temperature.

Answer explanation

Plants play a crucial role in the greenhouse effect by absorbing carbon dioxide during photosynthesis. This process helps reduce the concentration of this greenhouse gas in the atmosphere, thereby mitigating the greenhouse effect.
