Cirrus
Cumulus
Stratus
Cumulonimbus

26
Q

Levels where clouds form at

A

Cirrus clouds form at the highest altitude
Cumulus clouds form at middle altitude
Stratus clouds form at low altitudes

27
Q

Appearance of clouds (what they look like)

A

Cirrus clouds appear wispy and feathery (malls tell)??
Cumulous clouds appear puffy
Stratus clouds appear like a flat and gray blanket

28
Q

The kinds of precipitation are

A

Liquid precipitation or rain

Solid precipitation which comes in many forms

29
Q

The kinds of solid precipitation are

A

Hail, sleet, and snow

30
Q

Draw a cold front, warm front, and stationary front

A

Good job

31
Q

Occluded front

A

When cold air runs into warm air, it pushes up as it rises, it condenses. Clouds form and storms may follow

32
Q

Cold front

A

Warm air rises over cold air flows underneath

33
Q

Warm front

A

Front row on the air moves against cold with steady rain

34
Q

Stationary front

A

Stays in one place and looks like Cold air is on one side and warm air is on the other side in a strait vertical (up and down) line

35
Q

The weather in an area is affected by

A

The air mass that is passing

36
Q

The front happens when

A

One air mass meets a different air mass

37
Q

Kinds of fronts

A

Cold front
Warm front
Stationary front

38
Q

When a cold air mass moves into an area where the Air mass is warm

A

Dence heavy a cold air mass pushes up the lighter warm air

39
Q

A stationary front is

A

A boundary by which two different air masses and whether moves

40
Q

A stationary front forms when

A

The time the temperature and humidity of the air masses moved behind the front

41
Q

The jetstream is

A

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

42
Q

The jetstream moves

A

Air masses

43
Q

Over North America the jetstream moves from

A

West to east

44
Q

High and lows what are the systems?

A

Low pressure system

High pressure system

45
Q

Knowing the location of low pressure system and high-pressure systems and tell you about

A

Local weather conditions

46
Q

A low-pressure system is

A

A large air mass with low pressure in the air

47
Q

Since warm humid air has low-pressure, it usually brings weather that is

A

Warm and stormy

48
Q

high-pressure system is

A

A large air mass with the highest air pressure in the center

49
Q

Since cool, dry air has high pressure, this system usually brings

A

Dry, clear weather

50
Q

On a weather map, symbols represent different variables like

A

Cold friends and warm fronts

51
Q

Cold fronts are shown by

A

Bluelines with blue triangles

52
Q

Warm fronts are shown by

A

Red line of half circle

53
Q

Meteorologists are

A

Scientists who study Earth’s atmosphere and weather

54
Q

Meteorologists predict whether by

A

Measuring variables

55
Q

Are meteorologists predictions always accurate, why or why not?

A

No because sudden changes in one variable can change the weather

56
Q

How is technology used to study weather

A

Weather balloons, radar and satellite

57
Q

Weather balloons

A

Measuring height in the atmosphere

58
Q

Radar provides information about

A

Precipitation and wind

59
Q

Satellites provide information about

A

Temperature, wind, moisture, clouds and cloud cover
