What is the atmosphere?
Layers of protective gas that surrounds the Earth
What is evaporation?
The process by which the sun turned the water into a vapor
What is the thermosphere?

What are Aerosols ?
solid particles, such as salt evaporated from oceans and pollution
Why is the cryosphere necessary?
To keep the earth cold by reflecting the sun energy back into the atmosphere
How does the atmosphere exist?
Gravity keeps close to earth
The atmosphere changes over millions of years and continues to change even today
what is it when water soaks deeper into the ground water by a gravitational pull?
Percolation
What is the exosphere?
The ex fear is the outer most layer. It is extremely thin. It does not have a specific outer limit atoms and molecules escaped into space from this region.
What is carbon dioxide?
Greenhouse gas, that traps heat from the sun and warms the earth
Why is the cryosphere so important?
It prevents the earth from getting too warm
it is vital for the living organisms that depend on it
What are 4 things in the atmosphere??

carbon dioxide
what is surface runoff?
When water doesn’t soak into the ground, but flows on a path to a river
what is the stratosphere?
Contains the ozone layer that absorbs ultraviolet raise from the sun. this heats the stratosphere protects us
