Team: Mars by Mind Map: Team: Mars

1. Mars has a very thin atmosphere. It consists of 95% carbon dioxide (CO2), 3% nitrogen, and 1.6% argon (there is no oxygen). The atmospheric pressure is only a fraction of that on Earth (about 1% of Earth's atmospheric pressure at sea level), and it varies greatly throughout the year.

2. Mars, the red planet, is the fourth planet from the sun and the most Earth-like planet in our solar system.

3. The surface of Mars is dry, rocky, and mostly covered with iron-rich dust. There are low-lying plains in the northern hemisphere, but the southern hemisphere is dotted with impact craters. The ground is frozen; this permafrost extends for several kilometers.

4. Size

4.1. It is about half the size of Earth and has a dry, rocky surface and a very thin atmosphere.

4.2. Mars is about 4,222 miles (6790 km) in diameter. This is 53% (a little over half) of the diameter of the Earth.
