Term
Freezing
Definition
The process by which a liquid turns into a solid. What you have to do is -thermal energy
Term
Relative Humidity
Definition
% of water vapor in the air compared to the max. or the total amount of water vapor the air could hold in the atmosphere.
Term
Global Winds
Definition
Winds that blow steadily from specific direction over long distances. It is caused by uneven heating in the poles and the equator.
Term
Melting
Definition
The process by which a solid is turned into a liquid. You have to - thermal energy.
Term
Boiling
Definition
The process of turning a liquid into a gas. You have to add thermal energy. It happens throughout the liquid.
Term
Evaporation
Definition
The process by which water molecules in liquid water escape into the air as water vapor. It is a liquid to gas phase change that only happens at the surface. YOu add thermal energy.
Term
Windchill Factor
Definition
Combining temperature and wind speed. Its a measure of how cold it is with the wind.
Term
Condensation
Definition
The process by which molecules of water vapor in the air become liquid. Its a gas to liquid phase change that you need to -thermal energy.
Term
Gas
Definition
A state of matter that has VERY spread out molecules that move freely. It has no fixed shape or volume.
Term
Jet Streams
Definition
Bands of wind that blow about 10 Km's above earths surface. From west to east.
Term
Humidity
Definition
The amount of water vapor in the air. It depends on the temp.
Term
Liquid
Definition
A state of matte with particles that are spread out. Ir has a fixed volume but no fixed shape.
Term
Solid
Definition
a state of matter with particles that are very squished together. It has a fixed shape and volume.
Term
Water Cycle
Definition
The movement of water between earths surface and the atmosphere.
Term
Wind
Definition
The horizontal movement of air from a area of high pressure to an area of low pressure.
