What type of rock is?

Answer 1

There are three major types of rocks: igneous, metamorphic, and sedimentary. Rocks are classified based on the process by which they were formed. Sedimentary rocks form from sand, dust, and tiny rock particles that are fused by water and extreme pressure over time. Igneous rocks form from cooled magma or lava; depending on how fast they were cooled and solidified, igneous rocks may or may not go through crystallization. Metamorphic rocks are rocks that changed from either sedimentary rocks, igneous ones, or other metamorphic rocks. These generally form from wind, water, or chemical erosion.
