Question

Layer that is Considered a soft plastic because it is malleable and flows
GPT-4o mini
The layer you are referring to is likely the **asthenosphere**, which is part of the Earth's upper mantle. The asthenosphere lies beneath the lithosphere and is composed of semi-melted rock that is capable of slow flow. This property allows tectonic plates to move over it, making it critical for plate tectonics. Its malleable and somewhat plastic behavior is an essential characteristic that contributes to the dynamic processes of the Earth's crust.
