Question 19

What happens on a sunny day regarding air and clouds?

Answer 19

The sun heats the land, which heats up the air above it, causing the warm air to rise and form cumulus clouds.

What are cumulus clouds commonly referred to as?

Answer 20

Fair weather clouds.

Question 21

Do cumulus clouds generally produce rain?

Answer 21

No.

Question 22

What indicates the formation of cumulonimbus clouds?

Answer 22

Cumulus clouds growing bigger and rising higher.

Question 23

What are cumulonimbus clouds also known as?

Answer 23

Thunderstorm clouds.

Question 24

When are cumulonimbus clouds most common?

Answer 24

In the summer.

Question 25

Describe the shape of cumulonimbus clouds.

Answer 25

They are often flat-topped with sharp edges near the ground and wispy edges higher up.

Question 26

Where do cirrus clouds form?

Answer 26

Very high in the sky.

Question 27

What are cirrus clouds made of?

Answer 27

Ice crystals.

Question 28

What shape can cirrus clouds take when carried by wind?

Answer 28

A hooked shape.

Question 29

What does it mean if cirrus clouds get low and thick?

Answer 29

A warm front may be coming.

Question 30

What occurs at a warm front?

Answer 30

Warm air rises over cold air, leading to cloud formation.

Question 31

What is stratus cloud characterized by?

Answer 31

A low sheet of clouds covering the sky.

Question 32

How do stratus clouds form?

Answer 32

By air slowly rising or when wet air moves over cold land or sea.

Question 33

What is a fun fact about stratus clouds?

Answer 33

Stratus is the same as fog.

Question 34

Where are lenticular clouds typically found?

Answer 34

Near mountains.

Question 35

How do lenticular clouds form?

Answer 35

As air is blown up and over mountaintops.

Question 36

What happens to the air after it passes over the mountain?

Answer 36

It sinks back down and warms, causing the cloud to evaporate.

Question 37

Describe the Kelvin-Helmholtz cloud.

Answer 37

It looks like ocean waves and is formed by air masses moving at different speeds.

Question 38

What do Kelvin-Helmholtz clouds help us visualize?

Answer 38

How air is moving over our heads.
