4. The lowest layer of Earth’s Atmosphere…. The TROPOSPHERE
-The Troposphere is the lowest layer of the atmosphere, and
makes up about 75-80% of Earth’s atmosphere.
- The Troposphere is where all of Earth’s weather occurs.
- The higher you go up the Troposphere, the colder it gets.
The air also gets thinner as you travel upward of the

because nearly all of
the water vapor and
dust particles in the
atmosphere are in
the Troposphere.
- At the top of the
Troposphere, there
is a place called the
Tropopause, where

6. The layer containing the ozone layer…. The STRATOSPHERE
-The Stratosphere is
the layer in Earth’s
atmosphere, which
contains the Ozone
Layer.
- The Stratosphere’s
Ozone Layer absorbs
ultraviolet light from
the sun.
- The Stratosphere is

- Without the Stratosphere’s Ozone Layer, harmful
radiation from the sun would reach Earth.

8. The layer where meteorites burn up…. The MESOSPHERE
- The Mesosphere
is the third lowest
layer in Earth’s
atmosphere, and
this is where
meteorites burn
up, before they
reach Earth.

10. The layer above the Mesosphere… The THERMOSPHERE
-The Thermosphere is one of the upper layer s of the
atmosphere. It also includes the exosphere, and
ionosphere. The exosphere is above it, and the ionosphere
is below.
- Aurora Borealis occurs in the Thermosphere, charged
particles emit photons of light which forms the aurora.
- Temperatures climb sharply in the lower portion of the
Thermosphere. Temperatures in the upper Thermosphere

Thermosphere.
