New research provides better look at ocean plate under Central America

Convection in Earth's mantle is the "engine" driving plate tectonics. Hot material rises to the Earth's surface from the boundary between the planet's core and mantle, at a depth of about 3000 kilometers. Cold material then flows downward due to oceanic tectonic plates sinking into the mantle at subduction zones on the Earth's surface.
