Which is the most abundant gas in Earth's atmosphere?

nitrogen

water vapor

oxygen

carbon dioxide

13.

1 point

Which of these statements about the atmosphere is correct?

air does not exert any pressure

pressure exerted by air increases with latitude

air pressure is exerted only in a downward direction

air pressure decreases with altitude

14.

2 points

Why is the temperature of the four layers in the Earth’s atmosphere different?

Humans affect the temperature

Each layer is made up gasses that behave differently.

Air temperature goes up as the elevation goes up.

The amount of energy from the sun is different for each layer.

15.

2 points

Elevation increases

Elevation decreases

Air pressure decreases
