How does a simmering pot of spaghetti sauce illustrate convection currents?(1 point)

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 pot is only simmering, so there are no convection currents.

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 illustrates convection currents as the heated sauce at the bottom of the pot becomes less dense and rises, leading to cooler, denser sauce moving down to be heated.
