Start with this:
Venus is a huge ball of gas that would kill you very quickly
Venus has winds sometimes topping 1000 miles an hour, and has continues tornadoes on it
Mars is full of red dust, has evidence of bodies of water (lakes, streams, etc.), and has ice on it (that is proven)
Mars has a little tornadoes that are made from dust that are relatively harmless
Earth is, well, earth.
