Heat as well as lava can seep from cracks in the ocean floor.
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.
The mid-ocean-ridge.

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.

Rocks have a north and south pole. The sea floor was discovered to have different magnetic poles on cracks in the ocean floor.
chemical compounds such as sulfides that come from cracks in the ocean floor.
Along rift valleys, lava pours out of cracks in the ocean floor, gradually building new mountains.
