EVERYDAY SCIENCE

Detailed explanation-1: -These are stratus clouds. Stratus clouds form when condensation happens at the same level at which the air stops rising. We notice this on days when the stratus clouds are spread across the sky and it becomes overcast. The skies may have these stratus clouds for days and it also brings rain.

Detailed explanation-2: -Stratus clouds are horizontal and stratified, or layered. Stratus clouds can blanket the entire sky in a single pattern. They usually occur close to the Earth. Stratus clouds often form at the boundary of a warm front, where warm, moist air is forced up over cold air.

Detailed explanation-3: -Frontal fog forms in much the same way as stratus cloud near a front when raindrops, falling from relatively warm air above a frontal surface, evaporate into cooler air close to the Earth’s surface and cause it to become saturated.
