There are some really dull things in the solar system, for example, asteroids don't do much except rotate around the sun and they can also be very dangerous etc if one was to come crashing to earth that would be the end of life full stop. However earth is different it possesses something that all the other planets and things in our solar system do not and that would be oxygen and life.
Rocks change over the years – so the surface of the earth hasn’t always looked the way it does now.
All the rock processes that we can see happening now – E.g erosion, sedimentation, volcanic activity, etc. Will have been going on for millions of years. Geologists can use that fact to explain how various modern landscapes were formed
This powerpoint was kindly donated to animals and plants couldn't have dug themselves into the middle of rocks – the rocks must of formed around them. This type of rock is made by sedimentation – particles eroded from existing rock get washed to the sea and settle as sediment. Over time, these sediments get crushed together to make new rock. www.worldofteaching.com
