a hydrothermal vent
Th water escapes through cracks in the ocean floor called hydrothermal vents.
Hydrothermal vents. These vents are locations where seawater penetrates the ocean crust, becomes heated by magma below the surface, and then rises back up through the vents, carrying minerals and nutrients. They support unique ecosystems teeming with specialized biological communities.
Heat as well as lava can seep from cracks in the ocean floor.

Seawater seeps into the ocean floor through cracks in the crust
The mid-ocean-ridge.
hydrothermal vent also called (white/black) smokers
1) Ocean water seeps down through cracks in the crust. 2) Water comes in contact with magma that heats it to a very high temperature. 3) The heated water then dissolves minerals from the crust and rushes upward. 4)The solution billows out of chimneys. When the solution hits the sea, minerals crystallize on the ocean floor.
huge cracks in the ocean floor are called trenches.
The location where lava pours out of cracks in the ocean floor is known as a mid-ocean ridge or a spreading center. This is where tectonic plates move apart, allowing magma to rise from the mantle and create new oceanic crust.
molten material and drilling samples
It is a place where volcanism or hot water heated by the underlying magma erupts on the ocean floor.
