The statement "<span>A hot spot is an area where material from deep within the mantle rises and melts through the crust above it" is TRUE. Hot spots are regions inside the Earth's mantle where anomalously hotter rocks melt and form magma that rise through the crust and melts through it. This happens in regions that are both near and far from plate boundaries.</span>
Ocean fossils found on the rocky mountains are because of tectonic plates crashing.
The outer core heats the mantle on convection currents.
Hope this helps!
