  4. What substance moves in a • convection current • in the asthenosphere? • A. Air • B. Heated rock • C. Water • D. Both A and C

  5. Heat from crust drives convection current. Hot sinks. Density increases. Cold rises. Density decreases. Mantle is cold. Particles cool. Analyze the following drawing of a convection current. Draw it and write in the correct information. Which way is the plate (above) moving? Left or Right?

  6. Identify and explain one real-life example of a convection current found in your home.

  7. Why might a rock sink into the Earth’s mantle?
