Compare the motions of a lava lamp with the motion of convection currents in the mantle!
MODEL CURRICULUM (GRADE 8) Earth and Space Science
TOPIC- Physical Earth
CONTENT STATEMENT- Earth’s crust consists of major and minor tectonic plates that move relative to each other. Convection currents in the crust and upper mantle cause the movements of the plates. The energy that forms convection currents comes from deep within the Earth.
GRADE 8 CONCEPTS- The relationship between heat from the Earth’s core, convection in magma and plate movement should be explored.
