Question

Earth has 3 layers, crust, mantle, and core. Which of these has the property of being mostly solid rock but can be like a viscous fluid and react to convection currents?

Core
Crust
Mantle

Answer 1

The layer of Earth that is mostly solid rock but can behave like a viscous fluid and react to convection currents is the **mantle**. It is composed of semi-solid rock that can flow slowly over time, allowing for convection currents that drive plate tectonics.
