What is the troposphere?

Back

The troposphere is the lowest layer of Earth's atmosphere, where most weather occurs and where gas molecules are most densely packed.

Front

Where do we live in the atmosphere?

Back

We live on the bottom of the atmosphere, which is the troposphere.

Front

Why is the atmosphere essential for life on Earth?

Back

The atmosphere regulates temperature, provides gases for breathing, protects from UV rays, and burns up meteors.

Front

What separates the layers of the atmosphere?

Back

The layers of the atmosphere are separated by temperature changes.

Front

What is the coldest layer of the atmosphere?

Back

The coldest layer of the atmosphere is the mesosphere.

Front

What is the stratosphere?

Back

The stratosphere is the second layer of the atmosphere, located above the troposphere, and contains the ozone layer.

Front

What is the thermosphere?

Back

The thermosphere is the layer of the atmosphere above the mesosphere, characterized by high temperatures and low density.

Front

What is the exosphere?

Back

The exosphere is the outermost layer of the atmosphere, where the atmosphere transitions into outer space.

Front

What role does the ozone layer play?

Back

The ozone layer, located in the stratosphere, protects living organisms by absorbing most of the Sun's harmful ultraviolet radiation.

Front

How does altitude affect air pressure?

Back

As altitude increases, air pressure decreases because there are fewer air molecules at higher elevations.
