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

Answer: D

Explanation:

Hot magma erupts from a crack in Earth’s crust with a very high temperature that will surely break the bond of water molecules in contact. As a result of this, The water molecules will become less dense and rise upward.

Therefore, "The water will become less dense and rise upward " is the best statement to describes what will happen to the seawater above the crack as a result of convection.
