Describe the process involved with the circular movement of magma in the mantle. Include the terms temperature, particle movement and spacing, density, rising and sinking in your explanation.
What is the magma nearest to the core is heated, the particles in the magma move faster and take up more space, density decreases, magma rises towards the surface, magma cools, particles slow down and take up less space, density decreases, magma sinks towards the core?
