That would be the result of a submarine volcano. Pillow lava is a common type of lava that submarine volcanoes produce.
No. A vent is the part of the volcano from which material erupts. One volcano can have multiple vents.
Mid-oceanic ridges are created where sea floor spreading takes place. These are called divergent boundaries and mark places where new sea floor is being created. They are tectonically active regions and can be characterized by undersea vents where magma comes up and cools quickly because of its contact with very cold water.
Hydrothermal vents were discovered in 1977 in the Pacific ocean.
Geothermal vents are constantly forming and closing as magma moves towards the Earths surface and cools as a result of Geological processes.
Hydrothermal vents.
Molten rock below the surface of the earth that rises in volcanic vents is known as magma,but after it erupts from a volcano its called lava and a crater is the hole of a volcano.
As basalt erupts from fissures and vents near the ridge tiny magnetic "domains"of iron-rich minerals like magnetite orient themselves with the magnetic field of the earth; just like little compass needles. When the lava cools the domains are locked in place thus recording the orientation of the magnetic field at the time they cooled.
Th water escapes through cracks in the ocean floor called hydrothermal vents.

oceanic vents or the cores of volcanoes Based on current information, it seems to be about 105C. You will find bacteria that live in these extremely hot conditions. They are referred to as thermophilic (heat loving) Mostly found in naturally occurring hot springs where the high mineral content of the water can increase the boiling temperature of the water they live in. Deep oceanic vents also provide similar conditions, but because the temperature drops rapidly as you move away from the vent, so the temp where various organisms live tends to be lower.
Magma or lava vents and gas vents. Also fumarole.
