Giant impact theory - Assignment ExampleGrains of dust collided and organise bigger objects known as planetesimals. During collisions, m any(prenominal) planetesimals break up during collision but the larger ones put up and become protoplanets and later planets.If these planetesimals had remained stationary, the solar system would be made of thousands of small objects such as planetesimals without any planets. Life would live been possible in small objects. Alternatively, planets would have been small. The third scenario is solar system would have formed.Larger planets have more than internal heat to lose comp ared to smaller planets. In addition, there is proportionately smaller surface area to lose the heat from. The larger the planet, the bigger the less the surface are per unit volume.Small worlds or planets cool faster than the big world. When the planets completely cool off, they become geologically dead (Seeds, Michael and Backman 15). Planet earth is yet to cool of compl etely and this means it is geologically active. Activities taking specify at the core of the earth are responsible for volcanism, movement of tectonic plates, cratering and others. Bigger plants are more geologically active. If rotation is faster, geologic activities
