Of course，scientists cannot answer all of our questions.If we ask，“Why does the ocean water taste salty”，scientists will say that the salt comes from rocks.When a rock gets very hot or very cold，it cracks.Rain falls into the cracks.The rain then carries the salt into the earth and into the rivers.The rivers carry the salt into the oceans.But when then we ask “What happens to the salt in the ocean？The ocean does not get saltier every year.” Scientists are not sure about the answer to this question.

　　We know a lot about our world，but there are still many answers that we don't have and we are curious.
