Digging up planets – the geology of the solar system

Professor Chris Ballentine of Manchester University looked at the geology of the solar system.  How do the planets differ in their geology? Why are they all so different? What is the earth’s geology like? How did it end up like this?

Mercury is definitely strange from a geological point of view, being not much other than a metallic core with a thin covering of surface rock.
