Question

in addition to earth, which planet has evidence of water on the surface?
mars
mercury
neptune
saturn

Explanation:

Scientists have found evidence of water on Mars, such as dried-up riverbeds, lake basins, and minerals that form in the presence of water. Mercury has a very thin atmosphere and extreme temperatures, making liquid water unlikely. Neptune and Saturn are gas giants with no solid surface where liquid water could exist in the traditional sense. Mars, however, has shown signs of past or present water activity.

Answer:

Mars
