 The land around you, no matter where you live, is made of rock. If you live in a place that has good rich soil, the soil itself is finely broken down or weathered rock.
People that live in a desert region can easily find rocks on the surface. These rocks lay on a surface of clay that is also a product of weathering rock. Weathering is the process of breaking down rocks and minerals into smaller pieces by water, wind, and ice.
Sedimentary rocks are formed from the breaking apart of other rocks (igneous, metamorphic, or sedimentary rocks) and the cementation, compaction and recrystallization of these broken pieces of rock.
The photo at the left shows layers of lava and ash in Hawaii that will, over time, and with the help of bacteria, break down into fertile soil.
