Let's visit to Mars - The Red Planet
28Mars is the 4th planet of our solar system. In the comparison of size Mars came after Mercury. This is the terrestrial planet which is made up of rocks. And those planets that are made up of frozen gas is made up of Jovian planets. In Mars the atmosphere is also just like Earth but the atmosphere is very thin. These planets are known as Jovian planets. There is tremendous amount of Iron oxide found on this planet and it's colour is also red. There was water once upon a time on this planet. Do you know why there is no water on this planet. There are two reasons for this. There is low atmospheric pressure and that's why water has evaporated. There was low gravitational force and that's why atmosphere doesn't hold the water vapour. And one more reason for the vanishing of magnetic field and for that the central part known as core becomes frozen. And that's why at the time of solar storm the warm wind gets reach to this planet and for that wind the surface temperature reaches above 100 degree celsius. And that's why the water evaporated. The ice cap has found on the polar region of this planet. Does on this planet their is no volcano. The reason for this is that it's core becomes cold. And for that reason it's magma becomes frozen. And for this reason their is no volcano exists on this planets.
