Answer:
The structure of the earth is divided into several layers including the crust, mantle, outer core, and the inner core.
Explanation:
- The crust makes the hard shell composition of the Earth. It is on the outermost side and most of the Earth's lifeforms live on it.
- The mantle makes the next layer in the 'interior of the Earth' that comes after the crust.
- The upper mantle has been observed to have a semisolid structure, unlike the lower mantle which has a solid structure.
- The core has of a semisolid outer core and a possibly entirely solid inner core.
