Question

why is earths outer core hotter than earths oceanic crust?
earths oceanic crust is denser than earths outer core is.
earths oceanic crust has lava flowing from the mantle.
earths outer core has a composition of solid iron and nickel.
earths outer core is deeper within earth than oceanic crust is.

Explanation:

The Earth's outer core is hotter than the oceanic crust because temperature generally increases with depth in the Earth. The outer core is much deeper within the Earth compared to the oceanic crust. The deeper layers are subjected to higher pressures and have retained more heat from the Earth's formation and radioactive decay processes.

Answer:

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