Two reasons: 1) Clouds are blown about by the wind; 2) the earth's atmosphere rotates with the Earth, but not exactly at the same speed (i.e. it's like a loose-fitting cover).

We hear that a cloud weighs many 1000's of much. So, what holds a cloud up interior the sky? A cloud is made up of tiny drops of liquid water. those are heavier than air, and slowly clear out downward. The smaller the drops, the slower they fall with the aid of air resistance. Turbulence and upward shifting air currents can keep them up for fairly a together as. yet, they do fall. The clouds of steam that we see popping out of the tea kettle are made up of drops of water. Water vapor is an invisible gas, as you are able to tell by using finding on the hollow between the tea kettle's spout and the clouds of steam. Water vapor is all around us, and this is lighter than air. It rises with heat air and upward shifting air currents. whilst this moist heat air enters a layer of chilly air, the water cools and condenses into tiny drops, will become component of a cloud, and starts off falling. It falls into the warmth air, and would evaporate returned, and flow up into the chilly air repeatedly returned. So, areas of a cloud are consistently disappearing and reforming. and that's what keeps a cloud up interior the sky. Why are some clouds dark? The sunlight can shine suited via a skinny cloud. yet, thicker ones are dark on backside, the place the sunlight's gentle would not penetrate. hurricane clouds are each and every now and then miles thick, and are darkest of all. Rain is whilst tiny drops replace into larger, in particular by using colliding and merging with different drops. Hail and sleet occurs whilst rain drops are blown upward into freezing air. Hail stones could be blown upwards many circumstances, each and every time gaining a layer of ice. Snow occurs whilst moisture solidifies around a mud particle, in calm air, and the ice crystals boost quite slowly.

Same reason why a small feather moves through the air when you blow it. Air currents and thermals - what the birds use when gliding in the air. Same reason you can fly a kite.

wind and air currents (could also include air instabilities, but thats pretty much wind)
