Convection in the ocean causes seawater to become less dense and rise upward due to temperature differences.
Convection refers to the vertical movement of a fluid due to temperature differences, creating circulation patterns.
When hot magma emerges in the deep ocean, the seawater above the crack will become less dense as it warms up and will rise upward, creating convection currents.
This process is seen in the mantle's convection cells and plays a crucial role in plate tectonics and the formation of new crust at divergent boundaries.
