Question

this diagram is a model of earths layers. use the words below to label the layers.
mantle
continental crust
oceanic crust
lithosphere
asthenosphere

Explanation:

1. The topmost thin, light blue layer is the thin crust under oceans, so it matches oceanic crust.
2. The layer below the oceanic crust (brown/upper solid layer) is the thicker crust of landmasses, so it is continental crust.
3. The thick, warm-toned layer (orange/red) below the crust is the Earth's thickest internal layer, so this is the mantle.
4. The lithosphere includes the entire crust and the rigid upper part of the mantle, so it corresponds to the combined upper solid layers (crust + top mantle).
5. The asthenosphere is the soft, ductile part of the upper mantle below the lithosphere, so it is the upper, more flexible section within the mantle layer.

Answer:

• Topmost thin blue layer: oceanic crust
• Layer below oceanic crust (brown): continental crust
• Thick lower warm-toned layer (orange/red): mantle
• Combined upper solid layers (crust + top mantle): lithosphere
• Ductile upper section of the mantle: asthenosphere
