study the image of earth’s interior. the top layer is labeled lithosphere. a point rising from the mantle is labeled ridge. black arrows move away from either side of the ridge. a trench is labeled on each side of the lithosphere. mantle is centered within an oval made of red arrows rotating counterclockwise below the lithosphere to the left of the ridge. asthenosphere is at the top of an oval made of red arrows rotating clockwise set to the right of the ridge below the lithosphere. the outer core is beneath the mantle. which phrase explains what the arrows show? how convection currents move in earth’s interior the location of heated material near earth’s surface where plates move as material cools in the outer core why the densities of materials remain constant at different layers
