Study Notes
- Earth is made of four layers: the Core (inner and outer), the Mantle, and the Crust (divided into plates).
- The inner core is solid, dense, and made of iron and nickel, reaching temperatures of up to 10,000 F.
- The outer core is a liquid layer of molten iron and nickel.
- Volcanoes are formed when magma from the mantle rises to the surface through gaps in the Earth's crust.
- The Ring of Fire in the Pacific Ocean is a region with many active volcanoes that pose risks to millions of people living nearby.
Explore the structure of Earth's layers including the Core, Mantle, and Crust, as well as how volcanoes are formed. Learn about the inner core, outer core, and the Ring of Fire in the Pacific Ocean.
