Why does snow fall slower than rain?
Owing to their lower mass and greater projected Area snowflakes experience significantly lower downward gravitational force and a higher air drag. Therefore snowflakes don’t get accelerated to terminal velocities typically attained by rain drops.
Does snow make noise?
Snowflakes do just that! As snow begins to melt and change shape sounds change yet again. … In fact as snow turns into ice it can actually make sounds louder because it will reflect sound waves instead of absorbing them.
Does it snow over the ocean?

Snow forms when tiny ice crystals in clouds stick together to become snowflakes. If enough crystals stick together they’ll become heavy enough to fall to the ground. … Snowflakes that fall through cold dry air produce powdery snow that does not stick together. See also what africa is really like
Why is snow not ice?
Snow and ice are made of the same material but snow is composed of crystals with regular shapes while ice forms as sheets or solid chunks. The difference between snow and ice lies in how water freezes into its solid form and here’s how that happens. … Normal air always has water vapor in it.
Is snow water safe to drink?
Answer: Drinking water made from clean white snow melt is generally considered safe because pathogens don’t usually survive in it.
What Colour is water?
The water is in fact not colorless even pure water is not colorless but has a slight blue tint to it best seen when looking through a long column of water.

Does rain start as snow?
Most rain actually begins as snow high in the clouds. As the snowflakes fall through warmer air they become raindrops. Particles of dust or smoke in the atmosphere are essential for precipitation. These particles called “condensation nuclei ” provide a surface for water vapor to condense upon.
