In the earlier of Earth's years; the Hadean from memory; there was no water and hence no hydro- anything. This was the first 700 million years or so. (Between 4.5 and 3.8 billion years ago.)
But some very old banded iron deposits come from this early, indicating that these were precipitated by changing chemical conditions.
Another few hundred million years later, the blue-green algae appeared, and having invented photosynthesis with its attendant release of oxygen, created the large banded iron deposits. And some soft-bodied fossils, such as the Ediacaran.
Hydrothermal vents.
Hydrothermal vents allow underground heat sources to warm the ocean bottom which is necessary to support deep see ecology.
Approximately 80% of the Earth's thermal vents, also known as hydrothermal vents, are found on the ocean floor. These vents are primarily located along mid-ocean ridges and are crucial for supporting unique ecosystems. The remaining 20% are found on land, primarily in geothermal areas such as hot springs and fumaroles.
Black and white smokers are submerged by hydrothermal vents at mid-ocean ridges, which are formed by volcanic activity along tectonic plate boundaries. These hydrothermal vents release hot, mineral-rich water into the deep ocean, creating unique ecosystems where extremophile organisms thrive.
The domain for bacteria that live in hydrothermal vents would be "Bacteria." They belong to the domain Bacteria in the three-domain system of classification, which includes Bacteria, Archaea, and Eukarya.
Type your answer here... what do Hydrothermal Vents look like
hydrothermal vents are found in the deep zone
Hydrothermal vents can get very tall. Many of them are as tall as a three story house.

Yes, some crabs have adapted to life near hydrothermal vents.
I have no clue
Hydrothermal vents are found along seafloor spreading centers on the bottom of the oceans.
Hydrothermal vents are typically located on the ocean floor where basaltic rock crust is present. The soil around hydrothermal vents is mainly composed of mineral-rich sediments and hydrothermal minerals like sulfides, which are deposited from the hot, mineral-laden fluids that flow from the vents.
Coral reefs and hydrothermal vents are similar because they both lie below the under water.
