Someone help me with this. Imagine you drank a big glass of water today. Ten years later,if you go to Antarctica and drink a glass of water probably one of the atoms you drank today will be in that cup. Write about how the atom got there. What did it 'see' along the way.
Well when you would "get rid of" the water it would eventually be led to some ocean, pond, lake, etc. There it would eventually evaporate, rising up to the sky. This is where it would move around with clouds until it rained again.
