are alone. Would it be possible that the universe and its planetary systems are much the

same? Let's take a look at one of our neighbors, Mars, and compare a few similarities with

Earth. Mars is much smaller than the Earth, and has no oceans, trees or other visible

forms of life on the surface. However, Mars does have several similarities with our own

planet. Three ways Mars and Earth are alike are that they both have continents, craters,

First of all, Earth and Mars both have continents. Continents are made of material

that is less dense than the rest of the terrestrial crust, which makes them lie higher than the

ocean floor. There are seven continents on Earth. The Earth's continents (from largest to

smallest) are Asia, Africa, North America, South America, Antarctica, Europe, and

Australia. There are the two regions on Mars which seem elevated above the rest of the

crust. The first is a large elevated region in the lower half of the planet known as the

Highlands. The other feature is known as the Tharsis Ridge or Bulge. It is the size of a
