Answer 1

How are clouds formed?
All air contains water,but near the ground it is usually in the form of an invisible gas called water vapor.When warm air rises,it expands and cools.Cool air can't hold as much water vapor as warm air,so some of the vapor condenses onto tiny pieces of dust that are floating in the air and forms a tiny droplet around each dust particle.When billions of these droplets come together they become a visible cloud.
How is fog formed?
There are many different types of fog,but fog is mostly formed when southerly winds bring warm,moist air into a region,possibly ending a cold outbreak.As the warm,moist air flows over much colder soil or snow,dense fog often forms.Warm,moist air is cooled from below as it flows over a colder surface.If the air is near saturation,moisture will condense out of the cooled air and form fog.With light winds,the fog near the ground can become thick and reduce visibilities to zero.
How does rain form?
Water droplets form from warm air.As the warm air rises in the sky it cools.Water vapor (invisible water in the air) always exists in our air.Warm air holds quite a bit of water.For example,in the summer it is usually very humid.When enough of these droplets collect together,we see them as clouds.If the clouds are big enough and have enough water droplets,the droplets bang together and form even bigger drops.When the drops get heavy,they fall because of gravity,and you see and feel rain.
How is snow formed?
Snow is commonly formed when water vapor undergoes deposition,which is when water vapor changes directly to ice without first becoming a liquid,high in the atmosphere at a temperature of less than 32°F and then falls to the ground.
