What’s Under Your Feet

The video explores the Earth's formation, describing it as a layered structure similar to a jawbreaker. It details the core, mantle, and crust, explaining their composition and characteristics. The core is divided into a solid inner core and a liquid outer core, both composed of iron and nickel. The mantle, the thickest layer, is made of molten rock, causing tectonic plate movement. The crust, the Earth's outermost layer, is thin and solid. The video also covers the three types of rocks: igneous, sedimentary, and metamorphic, explaining their formation processes and characteristics.

Explain the difference between sedimentary and metamorphic rocks.

How does the temperature change from the crust to the core of the Earth?
