sediements

Sediments are very special things first there is soil that is where most roots are. Then comes a clay like substance then rocks the clay is either very soft or something like melted rubber. But most of the time you can get through it without a drill next comes rocks which is well rocks. Then comes more clay soil dirt and rocks after all of that probably something like melted dirt and rocks then lava. After all of that the process repeats itself melted stuff rocks and clay and dirt then clay rock and soil again anyway that all for this time.
