Because the world made it that way
There is no change in the effect of gravity. However, water is more dense than air, so an object will fall through the air faster than it will fall through water. But it will still fall in the water......it's just that gravity has to fight against the added density of the water.
Yes, however, even air affects how fast something falls. The weight of the water is what causes buoyancy (certain materials to float), and and the resistance of water plays a small role - the weight of the water being the larger role - in what causes other materials to fall slower than they would through air. There are actually certain things that are buoyant in the air, like helium. You will notice that if you let all the air out of your lungs, you will fall down through the water at a certain (very slow) speed. That speed is your terminal velocity through water. The terminal velocity of an average sized human through the air is about 55.6 m/s (200 kph or 124 mph). This speed is obviously much higher than the speed at which something falls through water. So water does affect haw fast something falls. "But wait, certain objects appear to fall through the water at the same speed that they fall through the air!" To explain this, water affects how fast something falls - compared to how fast it falls through the air - depending on its density. The object which you're talking about, is actually falling slower through the water, you just can't tell. We see this property in air too, why do you think a pound of feathers falls much slower than a lead weight?
The name for raindrops that freeze as they fall through the air is sleet.
The type of friction that occurs when objects fall through the air is called air resistance or drag. This force opposes the motion of the object as it moves through the air, slowing it down.

airRain are water droplets that fall from the sky.If it is very cold, or there are layers of vary cold air that the rain passes through on the way down, the water droplets can become snow or balls of hail.
Yep, water has a high heat capacity which means it absorbs a lot of heat before it changes temperature and once absorbed, it holds onto it. You can't say the same for rocks or especially sand.
Clouds are made up of tiny water droplets or ice crystals that are suspended in the air. If you were to fall through a cloud, you would likely come into contact with these tiny water droplets, but they are so small and dispersed that they wouldn't make you wet like rain would.
Air Resistance or friction with the air.
Air Resistance or friction with the air.
The atoms or molecules in the air get pushed aside by the raindrops as they fall through, then the molocules close back up behind the raindrops. It's the same thing that happens when anything moves through the air.
No, in the vacuum of space where there is no air resistance, the cup and the water will fall at the same rate due to the effect of gravity. The presence of air does not affect the rate at which objects fall in a vacuum.
