Geology of a untitled world

(really) short story trying to describe the geology of a fantasy world

Geology

The planet is composed of 6 layers.

1. The Core, no one knows what it is made of since the magical concentration on the next layer makes it impossible to reach.

2. The Mana Sea, an endless ocean of pure raw magic.

3. The Molten Sea, molten rock and metals swirl in temperatures few can withstand.

4. The Hollow, an underground maze of tunnels and caves, the lower levels are hot and dry due to its proximity to the Molten Sea while the the upper parts are humid and cold.

5. The Underground, the space between the crust and the Hollow, it has gigantic pillars that support the crust or while the space between them is covered mostly in water connecting the oceans of the surface.

6. The Crust, the last layer of solid rock in which the surface stands on top of

There are two types of volcanoes, common volcanoes and magical volcanoes.

Common volcanoes spew ash, molten lava and gasses from the Molten Sea layer into the surface.

Magical volcanoes are connected to the Mana Sea and they dissipate magical energy into the atmosphere and nearby region.

Author's Note

I want to know if you can picture what I'm trying to explain in this, as in can you imagine how a cross section of this world would look like.
