Question

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

Explanation:

1. The outermost thin layer is the oceanic crust, matching the topmost labeled section.
2. The lithosphere includes the crust and the uppermost rigid part of the mantle, corresponding to the combined top two layers.
3. The soft, ductile layer beneath the lithosphere is the asthenosphere, matching the upper red layer.
4. The thick layer that includes the asthenosphere and extends downward is the mantle, corresponding to the combined lower two (red and orange) layers.

Answer:

• Top left label (outermost thin layer): oceanic crust
• Top right label (combined top two layers): lithosphere
• Bottom left label (upper red layer): asthenosphere
• Bottom right label (combined lower two layers): mantle
