The fraction of Earth which is covered in water.
What is 3/4?
100
This is the process of water becoming water vapor.
What is evaporation?
100
The blanket of air which covers Earth.
What is the atmosphere?
100
The area where to air masses meet.
What is a front?
100
This weather tool measures temperature.
What is a thermometer?
200
The percentage of Earth's water which is considered "usable".
What is 1% or 3%if you count frozen water.
200
In the water cycle, water cools to change from vapor back into liquid water.
What is condensation?
200
This is what happens to air pressure as air molecules can move further apart.
What is it decreases or goes down?
200
When a cold air mass bumps into a slow moving warm air mass.
What is a cold front?
200
This weather tool measures air pressure.
What is a barometer?
300
Ocean water is saltier in hot places for this reason.
What is water evaporates faster there?
300
During this process, liquid water falls back to Earth.
What is precipitation?
300
This is the direction warm air travels.
What is warm air rises?
300
When a warm air mass meets a slow moving cold air mass.

This ocean is the largest on Earth.
What is the Pacific Ocean?
400
This process occurs when liquid water collects up on the surface or underground.
What is accumulation?
400
The direction cool air travels.
What is down?

What are cold and warm fronts?
500
These are the three states in which water can be found.
What are solid, liquid, and gas?
500
This is the never ending movement of water from the surface through the atmosphere and back again
What is the water cycle?
500
Air pressure is higher here.
What is near the surface of Earth?
500
The type of weather we can expect from a warm front.
What is long-lasting precipitation.
500
Most meteorologists use these high tech tools to help them predict weather.
What are computers or radar?
