Question

In an area of the deep ocean, hot magma emerges from a crack in Earth’s crust. Which statement describes what will happen to the seawater above the crack as a result of convection?

Water molecules will break apart and flow in a circular pattern.
Water molecules will bond together and rise upward.
The water will become more dense and sink downward.
The water will become less dense and rise upward

Answer 1

The water will become less dense and rise upward.

Explanation: Heating from the magma warms the seawater, lowering its density so it rises. Cooler, denser water then sinks, producing convection currents.
