What happens to water once it reaches earths surface?

It either soaks into the ground, eventually ending up in acquifers. Also it runs off into creeks and rivers, eventually reaching the ocean. Once it goes into the ground it becomes ground water.

So what you would do is go through and add 3 teaspoons(tsp) 6 times because of the 6 tablespoons(tbsp). which will give you an answer of 18. another way is to multiply 3x6=18.

It could possibly be beneficial if the experiment is successful.
