Water Cycle
The driving force of the water cycle.
What is the sun?
The region of the Earth receives the most sun light.
What is the Tropical Zone?
What is an air mass?
An air mass is a large volume of air in which temperture and humidity are the same.
What type of pressure system is associate with fronts?
low pressure
How are surface currents caused?
Wind moves the water and causes surface currents.
This occurs when surface water heats up and becomes water vapor.
What is evaporation?
These regions of the Earth are coldest becasue they do not receive as mich direction sunlight as the equator.
What are the poles?
Where do fronts form?
Fronts form where two air masses meet.
What air pressure system causes air to sink?
High pressure.
How do ocean currents influence weather?
Ocean currents circulate heat around the globe
OR
Ocean currents influence the air masses above them.
This occurs when water vapor rises in the atmosphere, then cools down to turn into water droplets.
What is condensation?
How the earth's atmosphere is heated?
unevenly
When a cold air mass overtakes a warm air masses, and slips underneath it.
What is a cold air mass?
What air pressure system causes air to rise?
A low-pressure system.
What does the ocean currents near the equator carry toward the poles?
They carry warm water (with energy from the sun).
When plants release water vapor.
What is Transportation?
What causes wind?
Differences in air pressure and temperture.
An air mass that is moist and cold.
What is a Maritme Polar air mass?
What type of weather is associated with high pressure?
Clear skies
What do hurricanes need to form?
Warm ocean water.
This is the driving force that causes water on the surface of the Earth to move downhill toward the ocean.
What is gravity?
This causes global wind belts to curve around the Earth?
The Corialis Effect
OR
The rotation of the Earth on it's axis
When a warm air mass is caught between two cold air masses.
What is an occluded front?
What type of front is associated with severe thunderstorms?
Cold fronts.
What ocean current influences our weather in South Carolina?
The gulf steam
