How does a simmering pot of spaghetti sauce illustrate convection

Question

currents? (1 point)
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 pot is only simmering, so there are no convection currents.
Warmer sauce at the bottom of the pot is denser, so it rises, forcing
cooler sauce down, where it is warmed.
Warmer sauce at the bottom of the pot is less dense, so it rises,
forcing cooler sauce down, where it is warmed.

Answer 1

Warmer sauce at the bottom of the pot is less dense, so it rises, forcing cooler sauce down, where it is warmed. This illustrates convection currents as the warmer sauce rises and cooler sauce sinks, creating a circulation of heat throughout the pot of spaghetti sauce.
