Answer

Brief Explanations:

The deeper one goes into the Earth, the higher the temperature generally is due to the geothermal gradient. The outer - core is much deeper than the oceanic crust, so it is hotter. The density of the oceanic crust compared to the outer - core is not related to temperature. Lava flowing from the mantle is not the main reason for the outer - core's higher temperature. The outer - core is liquid iron and nickel, not solid.

Answer:

Earth's outer core is deeper within Earth than oceanic crust is.
