Video: Earth’s Atmosphere
How do air pressure and temperature vary in the atmosphere?
Suppose you dove into a pool. The deeper you went, the more water there would be above you. The weight of the water above causes the pressure to increase as you go deeper.
Like water, air has weight, and pushes on you from all directions. Considering the example above, how do you think the pressure of the air above you would change if you climbed a mountain?

Learning Goals
weatherWeather is the condition of Earth’s atmosphere at a particular time and place.
atmosphere
The atmosphere is the envelope of gases that surrounds the planet.
ozoneThe ozone is the form of oxygen that has three oxygen atoms in each molecule instead of the usual two.
Water vapor*Not water vapor*
However, clouds form when water vapor condenses in the air to “hang out”
Water in the form of gas. Water vapor is invisible. It is not the same thing as steam, which is made up of tiny droplets of liquid water.
pollutant
Pollutants are harmful substances in the air, water, or soil.
Photochemical smog
Formed by the action of sunlight on pollutants such as hydrocarbons and nitrogen oxides. The chemical reaction forms a brownish mixture of ozone and other pollutants.
Acid rain
Rain is naturally slightly acidic, but rain that contains more acid than normal is known as acid rain.
