Mars is smaller than Earth (about 1/2 the diameter), and farther from the Sun. It has had surface volcanoes, but there is no molten core to provide a magnetic field.
The size difference means that the gravity of Mars is lower, about 38% of Earth's gravity. It has an atmosphere that is much thinner than Earth, and it is mostly carbon dioxide. Almost all of the oxygen present is bound as oxides in the red Martian soil.
The distance from the Sun means that it is much colderthan Earth. The ice at the Martian poles is mostly frozen carbon dioxide, and there is no liquid water anywhere on the surface. The combination of temperature and lack of water means that no Earth-like lifeforms are possible in the natural conditions on Mars.

How would the pull of gravity be different on Mars than earth?
The gravity on Mars is 0.379 that of Earth.
What planet has evidence of erosion by water?
Earth and Mars
Why is the weight of a buggy less on Mars than on Earth?
The gravity on Mars is less than on Earth, so although the mass of the buggy is the same on Earth and Mars, its weight is different because weight is equal to mass multiplied by the gravitational force. The gravity of Mars is 38 percent less than that of the Earth's. So, something that weighs 100 pound on Earth will weigh 38 pounds on Mars.
What is Mars size compared with Earth?
one year on mars is equivalent to 780 earth days
