Earth & Mars
The white patches at the poles of Mars are the planet's permanent polar ice caps. Like Earth, Mars has ice at its poles.
Earth, Mars,
There are nine planets in the Solar System. Two of them have ice covering both of the poles, call Polar Ice Caps. These two planets are Earth and Mars.
Two planets have frozen ice caps: Earth and Mars. In November 2012 scientists found evidence of ice on the poles of Mercury. However, only the Earth has oceans.
The red planet (or Mars) is a planet that contains both iron oxide and polar ice caps. Mars contains iron oxide in its soil, which gives the planet its red appearance.
Earth and Mars are the only planets known to have polar ice caps. Yes, I agree. However there is a possibility that Mercury has some ice in deep craters at the poles.
Earth has ice caps. And lots of dirt.
