Define convection.

Back

Convection is the transfer of heat through the movement of fluids (liquids and gases) caused by differences in temperature and density.

Front

What is the role of density in convection currents?

Back

Density differences cause warmer, less dense material to rise and cooler, denser material to sink.

Front

What is the significance of the Mid-Ocean Ridge in plate tectonics?

Back

It is a divergent boundary where new oceanic crust is formed through volcanic activity.
