Mars vs. Earth By: Mariesa G. and Brittany G.

Temperature Mars: • Mars is a cold planet with an average of -63°C. • The temperature on Mars ranges from a low of 140°C to a high of 20°C. • Mars is so cold that ice freezes over its poles Earth: • The earth’s temperature ranges from -127°F to 136°F ( -88°C to 58°C ). • Heat is trapped inside our atmosphere, thanks to the greenhouse effect.

Air Pressure Mars: • Mars has an air pressure of 6 k. Pa. • That is the equivalent of 6 millibars. Earth: • Earth has an air pressure of 32. 06 inches of Mercury. • ( 1085. 7 Millibars ).

Atmosphere Mars: • Mars atmosphere is incredibly thin • The atmosphere is made up of 95% carbon dioxide, 3% nitrogen, 1. 6% argon (argon- no oxygen so humans can’t live there. • Clouds containing carbon dioxide ice crystals are sometimes present. Earth: • Earth’s atmosphere is made up of 78% Nitrogen, 21% Oxygen, 0. 9% Argon, 0. 3% Carbon Dioxide.

Surface Conditions • • Mars: The surface of Mars is Rocky, Frozen, and Dry. The surface is covered in iron-rich dust. The northern hemisphere has plains On the other hand, the southern hemisphere of mars there are craters. Earth: • About 71% of Earth’s surface is covered with salt water oceans. • The other 29% of Earth’s surface is Continents and Islands.

Gravity Mars: • Mars only has 38% of Earths gravity. • For every hundred pounds you weigh on Earth you weigh 38 pounds on Mars. Earth: • The standard Gravity on Earth is 9. 80665 m/s 2. • In other words the gravity is 32. 1740 Ft. /s 2.

Distance From the Sun Mars: Earth: • Mars is 141. 6 million • Earth is 39 Million miles from the sun. • In other words… 227. 9 • That’s 149, 600, 000 million kilometers. Kilometers.

Rotation in a Day Mars: Earth: • There are 1. 03 Earth • Its takes the Earth days in one rotation of 23. 93 Hours to rotate Mars. around its axis. • That is, it takes 24. 6 • That’s one day on hours for Mars to earth. rotate one day.

Revolutions in a Year Mars: • It takes 687 Earth days for Mars to orbit the sun once – Mars’s years are 687 Earth days long. Earth: • It takes Earth 365. 65 days to orbit the sun. • That’s one Earth year.

Interesting Facts! Mars: • Mars is the most Earth-like planet in our solar system. • The Cydonia Mense region has rocks and other geologic figures that are aligned, looking like a human face. Earth: • The Earth is the closest to the sun around January 2 nd. This called perihelion. Its farthest from the sun July 2 nd. This is called the aphelion. • Earth is the only planet with Plate Tectonics.
