On Wednesday the 14th of December we held our unique earth expo, which was where we had to choose a topic that was related to how the structure and movement of the earth effects the way we live every day throuout the year and I chose the process of fossilisation.
Fossils are formed when an animal or plant dies in a damp area such as a bog or marsh, the the creature eventually decays, leaving just the skeleton or the (or the stem if it is a plant), then layers of mud build up upon the remains and they turn to rock, from being compacted by the layers, the it becomes a fossil.
