One way clouds form is when Earth's surface is warmed by sunlight, then warm air rises and cools to form clouds.
How do clouds impact the climate? And how will climate change impact evaporation and precipitation? Discover how rising global temperatures are likely to accelerate evaporation and increase rainfall, but not everywhere.
One way clouds form is when air is forced upward by a low pressure system.
