NASA Space Place: Mesosphere
NASA Space Place

The mesosphere lies between the thermosphere and the stratosphere.

NASA Space Place: Stratosphere
NASA Space Place

Above the troposphere and below the mesosphere, we have the stratosphere. 

NASA Space Place: Thermosphere
NASA Space Place

The thermosphere lies between the exosphere and the mesosphere. 

NASA Space Place: Troposphere
NASA Space Place

This layer gets its name from the weather that is constantly changing and mixing up the gases in this part of our atmosphere.

NASA Space Place: Earth's Atmosphere
NASA Space Place

Earth is a great planet to live on because it has a wonderful atmosphere around it.

NASA Space Place: How Does GPS Work?
NASA Space Place

When your phone tells you where you are, it may actually be listening to signals from satellites high up in space.

NASA Space Place: Exosphere
NASA Space Place

The exosphere is the outermost layer of our atmosphere. 

NASA Space Place: Ionosphere
NASA Space Place

An interesting layer called the ionosphere overlaps the mesosphere, thermosphere, and exosphere.

NASA Space Place: Make a Fan with Earth's Layers
NASA Space Place

To remember that Earth is much more than just the surface we see every day, make this Earth layer fan.

If you’re ever near the North or South Pole, you may be in for a very special treat.

NASA Space Place: How Far Away Is the Moon?
NASA

Often when we see drawings of the Earth and the Moon, they look really close together. Don’t be fooled! They’re actually really far apart.

NASA Space Place: Why Does the Moon Have Craters?
NASA

An asteroid or meteor is more likely to hit Earth because Earth is a lot bigger than the Moon, giving a meteoroid more area to hit! But we can see many thousands of craters on the Moon and we only know of about 180 on Earth! Why is that?
