While the soil of our favorite Red Planet may now seem arid and inhospitable- one where water is scarce or non-existent, this may not have been the case, billions of years ago.

- Michael M14년 이하I think the articles were very interesting. I think the streaks were formed by weathering and erosion. They must be eroded by the flow of water in summer; and by ice in the winter. The valleys were formed by the flow of water. I wonder where the water "if any water" went. The article "was the red planet once a lush blue" was more helpful to me because it answered a lot of questions that were very intresting.
- Shayne C.14년 이하I think that erosion on Mars is really interesting. When the scientists from University Illinois showed the evidence of dozens of valleys, more than twice as many, as was thought in the past. I thought that was really cool. There was also rivers in Mars that flowed into a giant ocean. Mars may have indeed received regular rainfall, which is also on earth. The map of Mars I thought was earth for a second. I thought is was really cool that there might be martians on Mars!
- JamesL14년 이하I spelled erosion wrong. I think. I can't check.
- JamesL14년 이하Was The Red Planet Once A Lush 'Blue' helped a lot. Since they found valleys, that means there must have been water on Mars. Since there was water, that means there must of been eroision on Mars!
- jiriesf14년 이하I think that erosion can't happen in space because theirs no mountains or sand. Maybe their used to be water on mars and a astroid hit it.
- Grace S.14년 이하I think that it would be strange if there were life on mars because scientists used to that the only planet with life on it was Earth

- Tanner B.14년 이하I think that 'Was the Red Planet once a Lush Blue?' was most helpful. It proved that there once was water on Mars better because it gave more information. I found it interesting that there was so many water-weathered and eroded landforms. The only landform that I knew about was Valles Marineris. It is fun to imagine what Mars once looked like and compare that to what Earth looks like now.

- Klavdia14년 이하I found it very interesting that there is an ocean on mars. I thought this planet had only dry areas because it is in space. Also, i thought it can only be dry because of the light gravity so wouldn't the water be in the air. A very interesting thing was that it had rainfall on Mars, how could that happen? And the erosion of water was very surprising to me.
