Answer:
Core is the densest layer of the earth.
Explanation:
The structure of the earth's interior is made up of several concentric layers. The earth's interior is divided into three layers- The Crust, the mantle and the core. The density of the outermost layer the crust is 3 g/cm^3. As we move towards the interior, the earth become more dense. The density of the second layer mantle ranges between 2.9-3.3 g/cm^3. The core is the innermost layer of the earth, surrounding the earth's center. the density of the core ranges between 9.5-14.5 g/cm^3.
Answer: One kind of evidence that supports Wegener's hypothesis is that: fossils of the same organism have been found on different continents Based on this finding, we can draw a conclusion that million years ago, all the lands on the face of the earth were not separated by sea so the animals could migrate from one continent to
