Explanation:
The energy of the earth's interior is known as the earth's internal energy. This powers the internal processes within the earth.
- This energy is very important in the rock cycle for the formation of both igneous and metamorphic rock.
- The energy is a product of frictional heating, radioactive decay of isotopes and heat that acreted when the earth was forming.
- The internal engine is responsible for mantle convection in which molten rock from within the earth rises to the surface and denser slabs of the lithosphere falls back within.
- It is responsible for the heating of sedimentary rocks to form metamorphic rocks around subduction zones.

Answer:
Monotremes, marsupials, and placentals are the three animals that could match this phylogenetic tree.
Explanation:
Monotremes, marsupials, and placentals belong from a common ancestor. Those organisms which have one common ancestor are also called monophyletic. These animals have some changes which occurs with the passage of time but most of characters are similar to each other. In placentals animals placenta is present while in Monotremes and marsupials this placenta is absent.
