How Clastic Sedimentary Rocks are Formed: Pre‑existing rock undergoes chemical and mechanical weathering by roots, acid rainwater, gravity, wind, and water. The broken particles are carried through water or air until they settle out in a lower area when the current wasn’t fast enough to carry the particles.

The three types of rocks. It's the first thing you learn in a geology class -- very briefly the three types of rocks are: Igneous -- they form from the cooling of magma deep inside the earth. They ...Rocks and minerals can be easily identified once you know what to look for. There are three different types of rocks: Igneous, Metamorphic and Sedimentary. Minerals must meet several requirements, including being naturally occurring and ino...Based on the mode of formation three major groups of rocks are defined: igneous, sedimentary, and metamorphic. Igneous Rocks — solidified from magma and lava. Sedimentary Rocks — the result of deposition of fragments of rocks. Metamorphic Rocks — formed out of existing rocks undergoing recrystallisation.
