What is the difference between Earth and Mars?

The planets Earth and Mars are both included in the Solar System yet they are very different planets. Earth, as humans have proven and testified, is readily-liveable planet compared to Mars. In our planet, living things are abundant while in Mars, there has not been an official record if there are really Martians living there. Earth is covered with different land and sea forms, while Mars has a barren land and frozen poles.

Due to the Earth’s shifting crust, land formations are replenished while the red planet does not have a change in the tectonic plates. Mars is smaller than Earth; compared to other planets in the solar system, Earth and Venus are almost have the same diameter.
