Answer:
On the outer shell, Earth’s crust is thin and rigid. The crust is all around us. Unless you’re not floating in outer space right now, it’s the layer you live on.
In comparison to other layers, the crust is mostly made up of rocks with a density from 2.7 to 3.3 g/cm3. The lithosphere is split between continental and oceanic crust. But both turn out to be very different from each other.As we move down through the crust into the mantle, we get into denser and heavier rocks. It’s not only density. But the further we go, the hotter it becomes.
Similar to how temperature fluctuates in the air on our planet, the temperature in the mantle varies. But it turns out that variation is even more extreme deep inside Earth.
The mantle’s structure is mostly silicates with density ranging from 3.2 to 5.7 g/cm3. 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 transfer of heat.As we move down through the crust into the mantle, we get into denser and heavier rocks. It’s not only density. But the further we go, the hotter it becomes.
