Exploring the Rock Cycle and Types of Rocks

The video provides an overview of the rock cycle, explaining the three main types of rocks: igneous, sedimentary, and metamorphic. It details the formation and characteristics of each rock type, including how igneous rocks form from magma, sedimentary rocks from sediment, and metamorphic rocks through heat and pressure. The video also discusses the rock cycle, illustrating how rocks transform from one type to another over time. The instructor uses relatable examples and analogies to make the content accessible to students.

What are the three main types of rocks discussed in the video?

• Igneous, Sedimentary, Metamorphic

• Sandstone, Limestone, Coal

• Basalt, Granite, Marble

• Slate, Quartz, Obsidian
