100

This type of front forms when a warm air mass overtakes  a cool air mass. It results in lots of precipitation and warm temperatures.

Warm front

100

The two characteristics of air masses.

Temperature & Humidity

100

The capital letter H stands for this on a weather map.

High Pressure Center

100

local wind that occurs at night

Land breeze

100

the last layer, farthest from earth

exosphere

200

This type of front forms when a cold air mass pushes  a warm air mass.

Cold front

200

An air mass that is dry and forms over land.

Continental air mass

200

A capital letter L stands for this on a weather map.

Low pressure center

200

local wind that occurs during the day

sea breeze

200

The layer in which humans live in

Troposphere

300

This front forms when two air masses collide, but neither air mass is strong enough to push the other out of the way.

Stationary front

300

An air mass that forms over the polar regions and is cold.

Polar air mass

300

Marked on weather maps as a blue line with triangles on it.

Cold front

300

global winds that blow from west to east.

The westerlies

300

The layer that contains the ozone layer.

Stratosphere

400

The type of front that develops when two cool air masses merge, forcing the warm air to rise and become trapped. Usually brings wind and preciptiation.

Occluded front

400

An air mass that forms over the tropics and has low humidity

Continental tropical air mass

400

Marked on a weather map as a blue line with blue triangles on one side and red half circles on the other side.

Stationary front

400

What causes the coriolis effect?

The rotation of the Earth

400

The hottest layer

Thermosphere

500

The type of front formed when a large mass of warm air takes over the cooler air mass. Usually produce rain, fog, or snow that lis light but steady.

Warm front

500

An air mass that forms over water and is cold 

Maritime polar air mass

500

Marked on the weather map as a purple line with half circles and triangles on the same side

Occluded front

500

global winds that blow northeast from the equator to  30 degrees north latitude and south latitude.

Trade winds

500

This is contained in the thermosphere
