What is the temperature trend in the troposphere?

• Temperature increases with altitude.

• Temperature decreases with altitude.

• Temperature remains constant with altitude.

• Temperature fluctuates randomly with altitude.

What is the function of the ozone layer?

• It protects Earth from harmful ultraviolet radiation.

• It helps in the formation of clouds.

• It regulates the Earth's temperature.

• It provides oxygen for breathing.

What is the primary gas in Earth's atmosphere?
