inner core
What layer of Earth contains the plates that cause earthquakes and volcanic eruptions?
The asthenosphere which is solid with the core.
The asthenosphere which contains the crust and mantle.
The lithosphere which contains the crust and outer core.
The lithosphere which contains the crust and upper mantle.
How can you describe the “heat flow” or convection currents in the Earth’s mantle?
When magma is heated by the core, it becomes dense and sinks. When magma cools, it becomes dense and rises.
The heat flow in the mantle bubbles up under the surface causing the surface to be warm.
When magma is heated by the core, it becomes less dense and rises. When magma cools, it becomes dense and sinks.
Heat flow comes up through volcanoes making the Earth warm enough to sustain life.
