Front

What type of cloud is altocumulus?

Back

Altocumulus is a mid-level cloud characterized by white or gray patches, often resembling cotton balls.

Front

Where are clouds made entirely of ice crystals typically found?

Back

Clouds made entirely of ice crystals are typically found at high altitudes.

Front

What phenomenon occurs when air moves from a high pressure area to a low pressure area?

Back

Wind occurs when air moves from high pressure to low pressure.

Front

What is a contrail?

Back

A contrail is a manmade cloud formed by the exhaust of jet engines, appearing as white streaks in the sky.

Front

What are the characteristics of stratus clouds?

Back

Stratus clouds are low, gray clouds that often cover the entire sky, resembling fog.

Front

What type of cloud is characterized by vertical development and can produce thunderstorms?

Back

Cumulonimbus clouds are characterized by vertical development and can produce thunderstorms.

Front

What is the role of humidity in cloud formation?

Back

Humidity is the amount of water vapor in the air; high humidity is necessary for cloud formation.

Front

What is the difference between cumulus and stratocumulus clouds?

Back

Cumulus clouds are fluffy and white, while stratocumulus clouds are low, lumpy, and gray.

Front

What is the significance of the dew point in weather?

Back

The dew point is the temperature at which air becomes saturated with moisture, leading to cloud formation.
