How does the water cycle remove pollutants from Earth's water?

Question

I can't find anything on this anywhere, but it's a question on my science test....hmm...

Answer 1

during the process of evaperation, only water turns into water vapor and travels into the atmosphere. the rest of the componds and pollutants are left on the surface, Eg-salt

Answer 2

When water evaporates, ONLY the water evaporates; all the other stuff stays behind. The evaporated water is water vapor, a gas, that mixes with the atmosphere. Later, water vapor in the atmosphere can form clouds and rain water back down on the ground. But it is just water, not a mixture of water and pollutants.

Answer 3

we live in a closed system nothing leaves this Earth

Water dilutes ,but everything has its limits

in principle

if you contaminate water it gets back to you in the end

you are water and so is everything else 99 molecules out of a hundred in most living things is water ,that is contantly being replaced

leaky vessels that are continuesly topped up

contaminate water is to to contaminate yourself
