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.
