Since Mars's atmosphere is much weaker than Earths, the sun's rays hit the ground and sort of roast the ground. Mars used to have oceans, or at least rivers, according to soil samples examined by NASA, but the sun caused them to evaporate a long time ago.

Does Mars have ocean?

well as far as we know, mars used to have oceans but they froze over. the ice is at the north and south poles. the rest is like a big desert i guess. but scientists believe that under the thick ice might lie a large ocean. that's all i know so far.


Where else you can find ridge?

Ridges can be found in mountain ranges, the ocean floor, and the surface of Mars. Additionally, ridges can also form on the roof of a building or on the back of certain animals.


What is the plural form of Mars?

The plural form of Mars remains Mars, as it is already a plural noun.


Does Mars have oceans on its surface?

There are a few signs which lead scientists to believe that Mars in fact did, and possibly still has, water in a liquid form. These clues are the river beds carved into the rock of Mars as well as the presence of Iron Oxide in the surface of Mars. On the 31st of July, 2008, NASA announced that it had found water on mars.


Why do scientists think Mars and Europa are good places to look for signs of life?

Because Mars and Europa are considered two of the most likely places to find liquid water. Mars is thought to have tiny amounts of water that become liquid in it's soil, theoretically allowing some particularly resilient forms of bacteria to survive, and there may be relatively large bodies of water deep beneath Mars's surface. Europa is thought to have a global underground ocean (similar to the way Earth has an underground global magma "ocean") with a volume greater than all the water on Earth.
