Main Concept: Geosphere
Sub-Concepts:
* Compositional Layers
* Crust:
* Thin, outermost layer
* Composed of lighter materials (rock)
* Divided into oceanic and continental crust
* Mantle:
* Thickest layer
* Composed of dense, silicate materials
* Plays a role in plate tectonics
* Contains:
* Asthenosphere: Hot, semi-molten layer, allowing for plate movement
* Mesosphere: Stronger, rigid layer below the asthenosphere
* Core:
* Innermost layer
* Composed mainly of iron and nickel
* Divided into:
* Inner Core: Solid, extremely hot, due to pressure
* Outer Core: Liquid, generates Earth's magnetic field
* Physical Layers:
* Lithosphere:
* Rigid, outermost layer, including crust and upper mantle
* Broken into tectonic plates
* Asthenosphere:
* Hot, partially molten, allowing for plate movement
* Mesosphere:
* Strong, rigid layer below the asthenosphere
* Outer Core:
* Liquid
* Inner Core:
* Solid
Connections:
* Crust: Part of the Lithosphere
* Asthenosphere: Part of the Mantle and a separate physical layer
* Mesosphere: Part of the Mantle and a separate physical layer
* Inner Core & Outer Core: Part of the Core and separate physical layers
Note: This is a simplified concept map. You can add more details, such as the thickness of each layer, specific rock types, and the role of each layer in geological processes.
