Topic 2 - Atmosphere

Greenhouse Effect

Gases in the atmosphere trap heat, making Earth's temperature suitable for life.

Greenhouse Gases

Gases like water vapor, carbon dioxide, methane, and nitrous oxide that contribute to the greenhouse effect.

Ozone

A protective layer in the upper atmosphere that shields Earth from harmful UV radiation.

Smog

Pollution formed by the interaction of pollutants and sunlight reactions, reducing visibility.

Stratosphere

The layer above the troposphere where temperature increases with altitude and the ozone layer is located.

Mesosphere

The coldest layer of the atmosphere where meteors burn up.

Thermosphere

The hottest layer of the atmosphere where auroras occur and radio waves are reflected.

Ionosphere

The upper part of the thermosphere where atoms split into ions and reflect radio waves.

Exosphere

The outermost layer of the atmosphere where satellites orbit Earth.

5 Layers of the Atmosphere

• Troposphere

• Stratosphere

• Mesosphere

• Thermosphere

• Exosphere

Troposhere

Layer of the atmosphere nearest to earth

Troposhere

The only layer of the atmosphere where life is possible.

Troposhere

All weather happens in this layer.

Troposhere

More than half the air in the total atmosphere is in this layer

Troposhere

Harmful ozone is found here

Water vapor

The most abundant natural greenhouse gas acts as natural feedback.

Carbon Dioxide

Released naturally through respiration and volcanic eruptions.

Methane

A gas produced naturally by wetlands, through agriculture activities, digestion in ruminants, and decomposition of wastes in landfills,

Nitrous Oxide

Generated by soil cultivation processes and the use of organic fertilizers

Good Ozone

What kind of Ozone is in the Stratosphere

Bad Ozone

What kind of Ozone is in the Troposphere

Troposphere

The layer closest to Earth where life is possible, weather occurs, and harmful ozone is found.
