Weather

Question 0

Maritime

Answer 0

Moist moisture

Question 1

Air Mass

Answer 1

• a large body of air that takes on the characteristics of the area over which it forms.
• formed when air stays over an area for a long period.

Question 2

Continental

Answer 2

Dry moisture

Question 3

Polar

Answer 3

Cold temperature

Question 4

Tropic

Answer 4

Warm temperature

Question 5

4 major cold air masses

Answer 5

• the continental polar
• The artic
• The maritime polar(over the Atlantic)
• The maritime polar(over the pacific

Question 6

4 major warm air masses

Answer 6

• The maritime tropical (Atlantic)
• The maritime tropical (gulf)
• The maritime tropical (pacific)
• The continental tropical

Question 7

Air mass movement

Answer 7

• as air mass moves, it begins to change
• this is call a Air Mass Modification
• helps predict weather

Question 8

Front

Answer 8

• The boundary between two air masses when they collide.

- the arrival of a front indicates a change in weather

Question 9

Types of fronts

Answer 9

1. cold
2. warm
3. occluded
4. stationary

Question 10

Cold front

Answer 10

• Forms when a cold air mass meets and displaces a warm air mass.
• because cool air is denser, it moves under the warm air, forcing it up quickly.

Question 11

Warm front

Answer 11

• occurs when warm air meets and overrides as a cold mass

- The less dense warm air moves over the cold air and gradually replaces it

Question 12

Stationary front

Answer 12

• Formed when a warm air mass and a cold air mass meet and neither moves.
• Tend to occur only when there is little difference in the temperature of air masses
• The weather produced is similar to a warm front

Question 13

Occluded front

Answer 13

• forms when a fast moving cold air mass overtakes a slow warm front
• The warm air is forced up as the 2 cold air masses collide
• Lead to cool temperatures and large amount of precipitation

Question 14

*Weather in the a Atmosphere

Answer 14

Water exists in the atmosphere as a solid, liquid or gas

• Solid: snow, sleet, hail
• Liquid: clouds, rain
• Gas: water vapor

Question 15

The water cycle

Answer 15

-The water cycle is the continuous movement of water in the earth's atmosphere.
3 major steps: 
1.evaporation
2.condensation
3.precipitation

Question 16

Evaporation

Answer 16

the process of water changing from a liquid to gas.

-Earths oceans, because they are so large, provide the greatest source of evaporating water

Question 17

Condesation

Answer 17

the cooling of water vapor, turning it back into a liquid

Question 18

Precipitation

Answer 18

• The tiny water droplets in clouds combine with one another

- Precipitation is any solid or liquid form of water that falls from clouds

Question 19

Groundwater

Answer 19

the water that is absorbed by the earths surface

Question 20

Runoff

Answer 20

happens when water falls on land and is not absorbed

Question 21

Humidity

Answer 21

• the amount of water vapor in the air.

- The more water evaporates into the air, the higher humidity gets

Question 22

*Formation of a cloud

Answer 22

• Water vapor rises and the air cools, it can now hold less gaseous water vapor.
• the air cools to a temperature, called Dew Point
• When the air reaches the dew point, water begins to condense around small dust or salt particles

Question 23

Cirro

Answer 23

(Height) high clouds, with bases above 6,000 m

Question 24

Alto

Answer 24

(Height) middle clouds with bases between 2,000 and 6,000 m.

Question 25

Strato

Answer 25

(Height) low clouds, below 2,000 m

Question 26

Cirrus

Answer 26

(Shape) latin for hair, wispy stringy clouds

Question 27

Cumulus

Answer 27

(Shape) Latin for pile or heap, puffy looking clouds

Question 28

Stratus

Answer 28

(Shape) Latin for layer, featureless sheets of clouds

Question 29

Nimbus

Answer 29

(Shape) Latin for cloud, low gray rain clouds
