Which of the following are the three types of rocks?

The three main types of rocks are igneous, sedimentary, and metamorphic.

Igneous rocks are formed through the cooling and solidification of magma or lava. Depending on where and how they are formed, these rocks can be classified as intrusive (formed below the Earth's surface) or extrusive (formed above the surface).

Sedimentary rocks, on the other hand, are created from the accumulation and compression of mineral and organic particles over time. They often form in layers and can contain fossils, giving insight into the Earth's history and past environments.

Lastly, metamorphic rocks are formed when existing rocks are subjected to high temperatures, high pressures, or chemically active fluids, leading to changes in their mineral composition and texture without the rock melting.

Understanding these three types of rocks and their formation processes provides essential insights into geology, the Earth's history, and various natural processes. The other options provide incorrect groupings or classifications that do not encompass the fundamental types of rocks recognized in geology.
