The Atmosphere

Front

What is scattering in the atmosphere?

Back

Scattering is the process by which dust particles and gases in the atmosphere reflect light in all directions.

Front

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

Back

Nitrogen is the most abundant gas in the Earth's atmosphere, making up about 78% of it.

Front

What is the layer of the atmosphere above the troposphere called?

Back

The layer above the troposphere is called the stratosphere.

Front

In which layer of the atmosphere does most of Earth's weather occur?

Back

Most of Earth's weather occurs in the troposphere.

Front

What is the layer of the atmosphere that contains the ionosphere and auroras?

Back

The thermosphere is the layer of the atmosphere that contains the ionosphere and auroras.

Front

What is the primary function of the stratosphere?

Back

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

Front

What is the significance of the troposphere?

Back

The troposphere is significant because it is the lowest layer of the atmosphere where weather occurs and where most of the Earth's air mass is located.

Front

What are the main components of the atmosphere?

Back

The main components of the atmosphere include nitrogen (78%), oxygen (21%), and trace gases such as argon, carbon dioxide, and water vapor.

Front

What is the role of the ionosphere?

Back

The ionosphere is a region of the atmosphere that is ionized by solar and cosmic radiation, playing a crucial role in radio communication and the formation of auroras.

Front

How does altitude affect temperature in the troposphere?

Back

In the troposphere, temperature generally decreases with increasing altitude.
