High- and Medium-Level Clouds

Clouds, composed of water, are influenced by air pressure, temperature, and humidity. High-level clouds, like cirrus, cirrocumulus, and cirrostratus, form in the upper troposphere and stratosphere, appearing transparent due to low moisture. Medium-level clouds, such as altostratus and altocumulus, are denser and allow sunlight to pass through. Lower-level clouds significantly impact weather, differentiating between sunny and stormy days.

What are high-level clouds primarily composed of?

• Water droplets

• Ice crystals

• Dust particles

• Gas molecules

Which type of high-level cloud is known for creating a halo effect?

• Cirrus

• Altostratus

• Cirrocumulus

• Cirrostratus

What is a characteristic feature of altostratus clouds?

• They form in a sheet covering a large area

• They are wispy and strand-like

• They are short-lived and turn into other cloud types

• They are similar to cirrocumulus but with larger tufts

How do altocumulus clouds differ from cirrocumulus clouds?

• Altocumulus clouds are at a higher altitude

• Altocumulus clouds are more transparent

• Altocumulus clouds are denser

• Altocumulus clouds have smaller tufts

Which type of clouds primarily influence the difference between sunny and stormy weather?

• High-level clouds

• Medium-level clouds

• All cloud levels equally

• Lower-level clouds
