How Do Sedimentary Rocks Form? - Earth How

Sedimentary rocks like shale, limestone and sandstone form from pre-existing rocks. If you start with sand, mud or organic material, these sediment deposits get eroded and transported over time. This happens because shorelines move back and forth compacting material below like a steam roller.
