Lake on Mars - level 2
Scientists found signs of an ancient freshwater lake on Mars.
They say that the lake probably covered an area 31 miles long and 3 miles wide. Analysis of the sediment shows that the lake existed for at least tens of thousands of years. The lake existed at a time when other parts of Mars were dry.
The lake could have supported life in a form of rock-eating microbes, which can be found on Earth as well.
The Curiosity Rover is currently en route to a three-mile-high hill of rock. It is going to look for life there.
Difficult words: ancient (very old), freshwater (water with no salt), sediment (material at the bottom of the lake), Curiosity Rover (NASA’s robot which explores Mars) en route (traveling).
