What is Weather?

• the condition of Earth's atmosphere at a certain time and place.

• another factor used in weather reporting

• amount of water vapor in the air.

• air that moves horizontally, or parallel

What is Temperature?

• measure of how hot or cold something is

• temperaure at which more condensation than evaporation occurs.

• the degree or intensity of heat present in a substance or object, especially as expressed according to a comparative scale and shown by a thermometer or perceived by touch.

• amount of water vapor in the air

How do air masses cause weather changes!

• the degree or intensity of heat present in a substance or object, especially as expressed according to a comparative scale and shown by a thermometer or perceived by touch.

• mass and forces the warm air to rise. As the warm air rises, its moisture condenses and forms tall clouds. As fronts move across Earth's surface, they produce changes in the weather. Triangles show the direction that a cold front moves.

• The atmosphere of Earth is the layer of gases, commonly known as air, that surrounds the planet Earth and is retained by Earth's gravity

• A front forms where two air masses meet.

• True

• False

What is the water cycle?

• continuous movement of water between the atmosphere, the land, the oceans, and living things,

• is condensed water vapor that is suspended in air

• the cycle of processes by which water circulates between the earth's oceans, atmosphere, and land, involving precipitation as rain and snow, drainage in streams and rivers, and return to the atmosphere by evaporation and transpiration.

• any form of water that falls to Earth from clouds.

An air mass is a large area of air that has the same

• temperature and humidity 
• density and temperature
• volume and humidity
• area and temperature

How does an air mass form?

• When the air does not move for a long time
• When it is over water
• When it is over a desert
• When the air moves quickly

If the air is coming from the desert, what will it feel like?

• hot and dry
• hot a moist
• cold and dry
• cold and moist
