What are mid-ocean ridges?
A
A chain of underwater waterfalls
B
A chain of underwater volcanos
C
A chain of underwater mountains
D
A chain of underwater rocks
Explanation: 

Detailed explanation-1: -The mid-ocean ridge is the most extensive chain of mountains on Earth, stretching nearly 65, 000 kilometers (40, 390 miles) and with more than 90 percent of the mountain range lying underwater, in the deep ocean.

Detailed explanation-2: -The mid-ocean ridge is a continuous chain of volcanoes on the ocean floor where lava erupts and the crust of the Earth is created. Nearly every day, somewhere on the crest of the mid-ocean ridge, there is likely to be an eruption of lava or an intrusion of magma that builds the ocean crust.

Detailed explanation-3: -Undersea mountain ranges are mountain ranges that are mostly or entirely underwater, and specifically under the surface of an ocean. If originated from current tectonic forces, they are often referred to as a mid-ocean ridge. In contrast, if formed by past above-water volcanism, they are known as a seamount chain.

Detailed explanation-4: -A. Mid-oceanic ridges are extensions of the land near the coast that is actually submerged under the ocean.

Detailed explanation-5: -The mid-ocean ridge is an extensive underwater mountain range resulting from the constantly altering tectonic plates, heat, and magma emitted from the earth’s core.
