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.
Answer
Brief Explanations:
Temperature increases with depth beneath Earth's surface (geothermal gradient). The outer core is far deeper inside the planet than the oceanic crust, so it experiences much higher temperatures. The other options are incorrect: the outer core is liquid iron-nickel, not solid; the oceanic crust is denser than the continental crust but less dense than the outer core; lava flows from the upper mantle, not the oceanic crust itself.
Answer:
Earth's outer core is deeper within Earth than oceanic crust is.
