If mars happened to get water what would the planet look like and how would we maintain our water source?

Diana H~ 1) what if Mars doesn't have all the characteristics of life to sustain life? 2) Some examples of systems could be the geospheres and hydrosphere. 3) Some similarities of the geospheres of mars and earth is they bot have rocks and volcanoes. A difference is that Earth has lots of water in different ways 3)Some similarities in the hydrosphere is that both mars and earth have been found to have water. A difference is that mars has small amounts of water.

Saphiah : 1) How did earth and the other planets form?2) Some similarities between their geosphere's are they have about he same amount of dry land, but mars has no water on the surface.3) Some similarities between their hydrosphere's are they had rocks that hold small pockets of water, but earth has lots of bodies of water suchh as, oceans, river, lakes ect...

joy : 1.) For the planets with extreme weather conditions.. How come there are no extra special peices of equipment to amkes sure the atronaut is safe? 2.)Some similarities between the Earth's geosphere and Mar's geosphere are that both geospheres show evudence of its past. Some differences between earth's geosphere and Mar's geosphere are that Earth has bodies of water, but Mars has holes made by craters. 3.) Some similarities between Earth's hydrosphere and Mar's hydrosphere is that both planets hydrospheres are amde completly of water and ice. The differences between Earth's hydrosphere and Mar's hydrosphere is that Earth has bodies of water flowing throughout, but Mars currently doesn't have any bodies of water.

illissia     how would we know if a another planet has all the things we need to sustain life.   they both have rocky and sandy geospheres.  earth also has water and mars has none.     earth has a a lot of liquid oceans and lakes when mars does not. they both have frozen water hidden.

wildiarys : we need to have many things we have here to live on mars. we need water, rocky , or sandy geospheres. we need water to be able to live. we need things we have here to be able to survive.

Paula Lopez) 1.What happens is mars doesn’t have the needs to sustain human life there? 2.Geospheres and hydrospheres are some examples of systems. 3)A similarities between earth and the geospheres of mars is that they both have volcanoes and rocks.A difference between earth and the geospheres of mars is that earth has more water and body’s of water than mars.

1) Scientist have been looking for evidence that there was a liquid water in the past on Mars. I wonder what build up Mars. Some examples of systems are geosphere, biosphere, and hydrosphere.2) Some similarities between the geospheres on Mars and Earth are that both have the same amount of rocky areas a difference they have is that Mars doesn't have water like Earth has. 3)A similarity Earth and Mars has with hydrosphere is that they Mars use to have water as a land form just like Earth a difference Earth and Mars has with hydrosphere is that Earth is built up with rivers, oceans, lake, and ponds but Mars doesn't.
