5th - U7 L1 - Weather Study Guide

Question 0

Fog

Answer 0

A cloud that forms near the ground

Question 1

Weather

Answer 1

The condition of the troposphere at any given place and time

Question 2

Front

Answer 2

When one air mass meets a different air mass

Question 3

Jet stream

Answer 3

A high altitude wind caused by the air temperature differences in air masses

Question 4

Air mass

Answer 4

A volume of air defined by its temperature and water vapor

Question 5

Forecast

Answer 5

A prediction about whether

Question 6

Stationary front

Answer 6

A boundary between two air masses where neither one is strong enough to move the other one. (So it does not move)

Question 7

Weather map

Answer 7

Map with symbols that represent different variables like cold and warm fronts

Question 8

How does water vapor form clouds?

Answer 8

Water vapor condenses around tiny particles of dust

Question 9

What determines the appearance of the cloud?

Answer 9

How high it forms in the atmosphere and the temperature is there

Question 10

Three types of clouds, you will need to know where they form and how they look.

Answer 10

Do cloud cards

Question 11

What is fog?

Answer 11

A cloud that forms near the ground

Question 12

What makes clouds thick and gray?

Answer 12

When water drops collide and condense, sunlight is not able to pass through

Question 13

Know how each type of precipitation forms

Answer 13

Rain – precipitation falls as rain when the air temperature is warm and water vapor is present
Hail - forms and some thunderstorm clouds when drops collide
Sleet - forms when raindrops fall through a layer of dry cold air near the ground
Snow – forms when air temperatures fall below freezing

Question 14

How is rainfall measured, how is snowfall measure?

Answer 14

• Rainfall is measured by a rain gauge which is a gauge that shows centimeters or inches
• snowfall is measured by a meter stick or a yardstick which is not always accurate

Question 15

Know what happens when a cold air mass approaches A warm air mass

Answer 15

A front happens which means a front is produced

Question 16

Know what the stationary front is

Answer 16

A boundary by which two different air masses and weather moves

Question 17

Know what the jetstream is, and how it affects the movement of weather in the United States

Answer 17

High altitude wind caused by large temperature differences in air masses. It is important because it moves air masses around the country

Question 18

Know what type of whether the high-pressure system brings and what type of whether the Low pressure system brings

Answer 18

• High-pressure systems bring dry clear weather

- low-pressure systems bring warm and stormy weather

Question 19

Weather maps: know the symbol for cold front and the symbol for warm front

Answer 19

The symbol for a cold front are blue lines with blue triangles
the symbol for a warm front is a red line of half circle

Question 20

Be able to explain one way technology is used to study weather

Answer 20

• weather the balloons measuring high in the atmosphere
• radar provides information about precipitation and wind
• satellites provide information about temperature, wind, moisture, clouds and cloud cover

Question 21

Be able to explain why measuring the amount of snowfall is not always accurate

Answer 21

Measuring snowfall is not always accurate because it can change. For example, wind can blow snow into drifts
