Question

Quizplus · Accepted Answer

Mars is a harsh environment with extreme temperature fluctuations, high radiation exposure, and thin atmosphere. It's unlikely that life, if it exists on Mars, could survive on the surface. However, evidence suggests that Mars may have had liquid water in the past and may still have water underground. If life did evolve on Mars, it could have adapted to survive in sub-surface environments, such as aquifers or hydrothermal vents. Therefore, the most promising place to search for life on Mars would be beneath the surface.
