A low-level cloud that comes in contact with the surface

• A. Cirrus Clouds
• B. Cumulonimbus Cloud
• C. Insolation
• D. Fog

Answer: (D)

Fog is a cloud that forms at ground level. When the air right at the surface becomes saturated with moisture—either by cooling to the dew point or by adding water vapor—tiny droplets condense and stay suspended near the ground. That creates a misty layer that reduces visibility, exactly like a cloud that touches the surface. Cirrus clouds are high, wispy, ice-crystal clouds up in the sky, not at the surface. A cumulonimbus cloud is a towering thunderstorm cloud that extends upward from near the ground through the atmosphere, not resting on the surface. Insolation is simply incoming solar radiation, not a type of cloud. So the low-level cloud that comes in contact with the surface is fog.
