"What does mantle convection look like?"
What will be an ideal response?
Answer: "Mantle convection explains why heat flow is greater through the seafloor than through continents and why decompression occurs that melts rock to form magma. Mantle convection occurs because upward-moving rock expands more by decompression than it contracts by cooling, allowing it to remain hotter and less dense than its surroundings, so it continues to move up. Likewise, sinking mantle compresses more because of high pressure than it expands by warming, so that it remains cooler and denser than its surroundings, and it continues to move down. Seismic tomography shows regions of the mantle where seismic waves travel slightly slower or slightly faster than in adjacent rock. The slower regions are interpreted to represent warmer, upwelling mantle, and the faster regions are interpreted to represent cooler, downward-flowing rock. Computer simulations of mantle convection produce patterns similar to those inferred by seismic-tomographic data."
