The Water Cycle Water on earth is constantly moving around, through and above the earth. How does it do this?! That is because it is in the three states we mentioned in lesson 1: vapor/steam, liquid and ice. The earth does not lose or gain much matter and this includes water. So, the same water that existed on earth millions of years ago, is still the same water that exists on earth today. Wow! Can you imagine that?! That simply means then that the same water used by the Romans many many many years ago is the same water we are using and drinking today. Imagine that! This is all made possible because of the water cycle. Below I have given you two different diagram of the same cycle. One is just more detailed than the other but examine both diagrams, listen to the audio description and you will get to choose which diagram you would like to use for the quiz. Yep, there's a quiz! The quiz is found under teh Assessment tab for Lesson 2. If you're up for the challenge and to gain extra points, conplete the water cycle diagram below on the left. Click below audio for transcript.
