Simple Internal Structure Of The Earth Diagram. The boundaries between these layers were discovered by seis. The earth has an outer solid layer called the crust a highly viscous layer called the mantle a liquid layer that is the outer part of the core called the outer core and a solid center called the inner core.
A cut away illustration of earth s interior. At the heart of our planet lies a solid iron ball about as hot as the surface of the sun. Made mainly of iron the temperature of the ball is 5 000 c to 6 000 c that s up to 6 000 times hotter than our atmosphere and scorching enough to make metal melt.
In this activity students will label a model of the earth students should include a description of each part in addition to the label and arrow.
This diagram shows us how thin the crust is in relation to the rest of the earth along with relative sizes of the mantle and core. The structure of the earth is divided into layers. A well known and simplified diagram of the interior of the earth. Core mantle and crust are divisions based on composition.
