Questions: Which type of cloud forms close to the ground when the temperature is just above the dew point? cirrus cumulus fog stratus

The answer is the third one: fog.

Explanation for each option:

• Cirrus: These clouds are high-altitude clouds that form above 20,000 feet and are composed of ice crystals. They do not form close to the ground.
• Cumulus: These are fluffy, white clouds that typically form at lower to mid-level altitudes but not directly at ground level.
• Fog: This is a type of cloud that forms very close to the ground when the temperature is just above the dew point, causing water vapor to condense into tiny droplets suspended in the air.
• Stratus: These are low-altitude clouds that can cover the sky like a blanket, but they are not typically at ground level.

Summary: Fog is the type of cloud that forms close to the ground when the temperature is just above the dew point.
