Earths Atmosphere

Front

What is the mesosphere?

Back

The mesosphere is a layer of Earth's atmosphere located above the stratosphere and below the thermosphere, where temperatures decrease with altitude. It protects Earth from meteoroids.

Front

What is the most abundant gas in Earth’s atmosphere?

Back

Nitrogen, which makes up about 78% of the Earth's atmosphere.

Front

Is Carbon Dioxide a trace gas?

Back

True, Carbon Dioxide is considered a trace gas in the atmosphere, making up about 0.04%.

Front

What is the second most abundant gas in Earth’s atmosphere?

Back

Oxygen, which constitutes about 21% of the atmosphere.

Front

Which two layers of the atmosphere get colder as altitude increases?

Back

The mesosphere and troposphere.

Front

What is the thermosphere?

Back

The thermosphere is the layer of the atmosphere above the mesosphere, characterized by high temperatures and the presence of ionized gases.

Front

What role does the stratosphere play in the atmosphere?

Back

The stratosphere contains the ozone layer, which absorbs and scatters ultraviolet solar radiation.

Front

What is the troposphere?

Back

The troposphere is the lowest layer of Earth's atmosphere, where weather occurs and temperature decreases with altitude.

Front

What is the ozone layer?

Back

The ozone layer is a region within the stratosphere that contains a high concentration of ozone (O3) and protects living organisms from harmful UV radiation.

Front

What is the significance of the atmosphere for Earth?

Back

The atmosphere provides essential gases for life, protects the planet from space debris, and regulates temperature.
