While the microbes that formed the mats generally are not preserved, the wrinkled striped patterns in the rocks suggest life was once there. In which type of environment did the limestone layer form? These particles make up only 10% of the matter of the universe (so, the brick wall in the photograph above is mostly empty space, but don't run into it!). 95 23 Most of the rocks exposed at the surface of Earth are sedimentary--formed from particles of older rocks that have been broken apart by water or wind.The gravel, sand, and mud settle to the bottom in rivers, lakes, and oceans.
