This layer is the closest to Earth's surface, and is where people, plants and animals all live.
What is the Troposphere?
This "sphere of layers" is also home to the Ozone Layer.
What is the Stratosphere.
Sandwiched between the Stratosphere and the Thermosphere, this layer of Earth's atmosphere is not just "mid".
What is the Mesosphere?
Don't bother bringing your thermometer, because this layer is the hottest!
What is the Thermosphere?
Your exit out of Earth's atmosphere is this layer.
What is the Exosphere?
The Troposphere is the only layer of the atmosphere with this phenomenon. Hope you brought your umbrella!
What is weather?
Planes often fly in the Stratosphere because there isn't much of this.
What is weather?
To help you remember the *ME*sosphere, you can remember that these space rocks burn up in this layer.
What are meteors?
The thermosphere is the hottest because it absorbs a lot of energy from this star's rays.
What is the Sun?
Unlike the Troposphere, the Exosphere is so far from Earth's surface that it has few air particles left, making it the...
What is the thinnest layer?
This is the prefix meaning of "Tropos"phere, to show how this layer of the atmosphere constantly mixes and moves.
What is "To Change"?
The Ozone Layer is like a giant shield that blocks most of this from hitting Earth's surface.
What are UV Rays/Ultraviolet Radiation.
Brrr! The Mesosphere is the coldest layer of the atmosphere, and as you rise through it, this happens.
What is "the temperature gets colder"?
This layer is where most of these space vehicles orbit Earth.
What are satellites?
Extending up to 6,500 miles above the Earth, it is hard to tell where the atmosphere ends and this begins. Far out!
What is outer space?
As you travel further up into the Troposphere, this happens to the temperature.
What is, "It gets colder?"
Ozone is actually an isotope of this element, with an extra atom making it O3.
What is Oxygen?
The "meso" in Mesosphere describes its position in the atmosphere's layers.
What is the middle?
Cosmic rays from the sun hit air molecules in the Thermosphere, making these beautiful displays at the Earth's poles.
What are the Northern/Southern Lights.
Because it's so far from Earth, the density of the Exosphere is this, compared to the other layers.
What is the least dense?
In terms of density, the Troposphere is the _____________ layer of the atmosphere.
What is most dense?
Without the Ozone Layer, UV rays would be giving us more sunburns and this very deadly illness.
What is skin cancer?
Known as our defender from space rocks, air molecules burn up meteors by hitting them and causing this reaction.
What is friction?
Despite how hot air particles get here, you probably won't feel the heat in the Thermosphere because air particles here are...
What is "spread far apart"?
While air particles are few and far between here, what air that is up here in the Exosphere is mostly made up of these two very common gasses, rather than Nitrogen and Oxygen.
What are Hydrogen and Helium?
