Do Astronomers think Mars once had water on its surface?
- No
- Yes
Correct Answer

A. Yes

Explanation

Astronomers believe that Mars once had water on its surface because of various pieces of evidence. The presence of dried-up riverbeds, polar ice caps, and minerals that can only form in the presence of water all suggest that Mars had liquid water in the past. Additionally, recent discoveries of underground ice reserves and the detection of water vapor in the atmosphere further support the idea that Mars had a watery environment in its earlier history.

Correct Answer

A. Gravity

Explanation

Gravity is the force that holds water on Earth. Gravity is the natural phenomenon by which objects with mass are brought towards each other. On Earth, gravity pulls everything towards the center of the planet, including water. This force keeps water from floating away into space and causes it to be held within the Earth's atmosphere and bodies of water such as oceans, lakes, and rivers.
