Layers of the Atmosphere

Front

What is the thermosphere?

Back

The thermosphere is a layer of the atmosphere located above the mesosphere, characterized by high temperatures and the presence of the auroras.

Front

What is the mesosphere?

Back

The mesosphere is the layer of the atmosphere above the stratosphere, known for having the coldest temperatures.

Front

What is the exosphere?

Back

The exosphere is the outermost layer of the atmosphere, where atmospheric particles are so sparse that they can travel hundreds of kilometers without colliding with one another.

Front

What is the stratosphere?

Back

The stratosphere is the layer of the atmosphere above the troposphere, containing the ozone layer which absorbs and scatters ultraviolet solar radiation.

Front

What is the troposphere?

Back

The troposphere is the lowest layer of the atmosphere, where weather occurs and where most of the atmosphere's mass is found.

Front

What is the Karman line?

Back

The Karman line is an internationally recognized boundary between the Earth's atmosphere and outer space, located at an altitude of 100 kilometers (62 miles) above sea level.

Front

What happens to particles when heat is supplied to them?

Back

When heat is supplied to particles, they gain energy and speed up, resulting in increased movement.

Front

What is the role of the ozone layer in the stratosphere?

Back

The ozone layer in the stratosphere protects living organisms by absorbing the majority of the sun's harmful ultraviolet radiation.

Front

How does temperature change with altitude in the troposphere?

Back

In the troposphere, temperature decreases with increasing altitude.

Front

How does temperature change with altitude in the thermosphere?

Back

In the thermosphere, temperature increases with altitude due to the absorption of high-energy solar radiation.
