The planet Mars is referred to as the “red planet” because of its reddish glow that can be seen in the evening sky. The planet Mars has two small moons. The first, Phobos is heavily crated. The second, Deimos, is much smoother. Both moons are merely miles across, unlike the Earth's moon.
The planet Mars is a desert planet. The atmosphere surrounding Mars is made up 95% carbon monoxide. It only has a slight trace of oxygen. The temperatures of Mars ranges between 190 degrees below zero to around 70 degrees Fahrenheit. While this is not as severe or extreme as some planets, it is still far too cold to support any human life.
The terrain of the planet Mars is full of deep canyons and large craters. There are towering volcanoes on the planet. Out of all of the planets in our solar system, Mars is home to the largest set of “mountains” and “valleys.” This area on the planet Mars is known as Tharsis Bulge. Atop Tharsis Bulge are four gigantic volcanoes. The largest of these volcanoes is three times taller than Mount Everest. Its base has been compared to the great state of Texas in regards to size. The valley or canyon known as Valles Marineris is deeper than the Grand Canyon. This canyon extends for 2500 miles, and is four miles deep in many areas.
Though these areas on the planet Mars are referred to as mountains, valleys and canyons, they are not like the ones on Earth. They are not teeming with life, rivers, forests, etc. Mars is a barren planet. It is covered with red sand, rocks, and dust. The low temperatures and pressure make it impossible for water to stay in liquid form. There are polar caps on Mars, however. You can see them through a telescope when you view Mars. They are white and stand out dramatically against the planets red glow.
