- Ryan Callanan14년 이하Scientists believe there is erosion on Mars. This is because they found dozens of streaks and a number of valleys. The scientists believe the streaks and valleys used to have salty water in them. The streaks would come and go with the seasons. They think the water ran down when it was warm and froze when it was cold. I would recommend this article to friends who are interested in learning about Mars because it talks about Mars and how there used to be water on Mars. It also shows some interesting pictures taken by the telescope.
