Exploring the Different Types of Rocks

The video tutorial introduces the concept of rocks, starting with a playful transition from rock music to geological rocks. It explains the three major types of rocks: igneous, sedimentary, and metamorphic. Igneous rocks form from cooled magma, with types like intrusive and extrusive. Sedimentary rocks are formed from compressed sediments, found in ocean beds and rocky surfaces. Metamorphic rocks result from the transformation of igneous and sedimentary rocks under heat and pressure. The video concludes with trivia, noting that the Earth's crust is mostly igneous rocks and the Taj Mahal is made of marble.

• Igneous, Sedimentary, Metamorphic

• Basalt, Granite, Marble
