Answer 2

Answer:

Physical characteristics. Mars is approximately half the diameter of Earth, with a surface area only slightly less than the total area of Earth's dry land. Mars is less dense than Earth, having about 15% of Earth's volume and 11% of Earth's mass, resulting in about 38% of Earth's surface gravity.

Composition by volume: 95.97% carbon dioxide; 1.93% argon; 1.89% nitrogen; 0.14...

Surface gravity: 3.72076 m/s2; (12.2072 ft/s2; 0.3794 g)

Surface area: 144798500 km2; (55907000 sq mi; 0.284 Earths)

Surface pressure: 0.636 (0.4–0.87) kPa; 0.00628 atm
