A submarine can avoid hitting the ocean floor by using sonar. However, sonar signals can be detected by other vessels, so using sonar

He proposed that the valley at the center of the ridge was a crack, or rift, in Earth’s crust. At this rift, molten rock, or magma, from deep inside Earth rises to fill the crack. As the ocean
