What is the function of the ozone layer in the atmosphere?

• It absorbs harmful ultraviolet radiation from the Sun.

• It produces oxygen for us to breathe.

• It traps heat to warm the Earth.

• It reduces greenhouse gases.

How does deforestation affect the concentration of carbon dioxide in the atmosphere?

• Increases, because there are fewer trees to absorb CO2.

• Decreases, because there are fewer trees to produce CO2.

• No effect, because other plants absorb CO2.

• Decreases, because it reduces the Earth's temperature.

• Grow plants under different colored lights and measure growth.

• Grow plants with varying amounts of water and measure growth.

• Grow plants in chambers with different CO2 levels and measure growth.

• Grow plants at different temperatures and measure growth.
