May 20, 2022 · Although heat usually corresponds to softening rocks, intense pressure keeps the lower mantle solid. Geologists do not agree about the structure of the lower mantle. Some geologists think that subducted slabs of lithosphere have settled there. Other geologists think that the lower mantle is entirely unmoving and does not even transfer heat by convection.

May 12, 2022 · The mantle’s structure is mostly silicates with a density ranging from 3.2 to 5.7 g/cm 3. Because the mantle and crust are made of rock, the transfer of heat is through convection. The hotter, fluid mantle causes the less dense crust to rise which consequently results in the transfer of heat.
