Sedimentary Rocks Origins

Sedimentary rocks are formed from erosion. particles of rocks are then washed into the ocean and slowly over the years lay down on the ocean floor. Accurately, around 100 million years ago, the layers of sedimentary rocks build up to be as tall as a few kilometers thick. The weights of the layers of sediment squash out water and the chemical process that it goes through will then bind or lock both the particles and the sediment to form solidified rocks. At the start sedimentary rocks are normally carried in rivers or land where there used to be water, in which then it gets buried then the process of naturally creation of sedimentary rocks begins.
