dry air humidity
Maritime tropical =
Hot air temp
Humid air humidity
Continental polar =

What causes weather to change?
When 2 air masses collide at different temperatures and they don’t mix easily.
What 2 things move the 4 major types of air masses
Prevailing westerlies and jet streams
The boundary where two air masses meet becomes what?
A front
Cold air is _________ and tends to ________
Dense
Sink
Warm air is ___ _____ and tends to ____.
Not dense
Rise
What front??
- Cold air mass and hot air mass meet but cannot move each other
- Fast moving warm air mass overtakes a slow moving cold air mass
- Warm air mass caught between two cold air masses.
- Fast moving cold air mass runs into a slow moving warm air mass and slides under the warm air mass
Stationary front
Warm front
Occulated front
Cold front
Tornadoes form when what two types of air masses meet?
When warm humid air mixes with cold dry air.
What is the difference between a tornado watch and a tornado warning?
A tornado watch is when a tornado had NOT been spotted but there is a possibility of one
A tornado warning is when a tornado HAS been spotted
Name the stage of the water cycle. What is precipitation? What is a runoff? What is condensation? What is evaporation?
Precipitation= liquid that formed the clouds becomes too heavy and falls to earth. Evaporation= the process in which water molecules in liquid water escape into the air as water vapor (gas) Runoff= the variety of ways water moves across land. Condensation= the process by which water vapor in the air is changed into liquid water
True or false?
Each cloud type is associated with a different type of weather?
True
Scientists classify clouds based on their ________ and _____
Altitude and shape
Clouds form when water vapor in the air condenses to form liquid ____ and ___ crystals
Water and ice
Water cycle

3 precipitation
4 runoff.
Plants in the water cycle
What stage of the water cycle do plants contribute to?
What is the name for the “sweating” they do?
Evaporation
Transpiration
The movement of water between the atmosphere and earths surface is called the _____ _____
Water cycle
________ is the measure of the amount of water vapor in the air
Humidity
What affects the air’s ability to hold water?
Temperature of the air
