Warmer sauce at the bottom of the pot is less dense, so it rises, forcing cooler sauce down, where it is warmed.

Warmer sauce at the top of the pot is denser, so it sinks to the bottom of the pot, where it is warmed even more.

The correct response is:
Warmer sauce at the bottom of the pot is less dense, so it rises, forcing cooler sauce down, where it is warmed.
This option accurately describes the convection currents in the pot of simmering spaghetti sauce. As the sauce at the bottom of the pot heats up, it becomes less dense, rises to the top, and cooler, denser sauce sinks to the bottom to be heated. This creates a continuous circulation of the sauce, illustrating the concept of convection currents.
