What do we call the chain of underwater mountains running through all the oceans?

What do we call the chain of underwater mountains running through all the oceans?

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 in the deep ocean. The nearly continuous, global mid-ocean ridge system snakes across the Earth’s surface like the seams on a baseball.

What is the underwater mountain chain that is formed by the sea floor spreading called?

mid-ocean ridge
A mid-ocean ridge (MOR) is a seafloor mountain system formed by plate tectonics. It typically has a depth of ~ 2,600 meters (8,500 ft) and rises about two kilometers above the deepest portion of an ocean basin. This feature is where seafloor spreading takes place along a divergent plate boundary.

What is the name of the process by which mid-ocean ridges continually add new material to the ocean floor?

sea-floor spreading
New ocean floor forms along cracks in the ocean crust as molten material erupts from the mantle spreading out and pushing older rocks to the sides of the crack. New ocean floor is continually added by the process of sea-floor spreading.

What do you call on the underwater mountain?

seamount
A seamount is an underwater mountain. A rise is an underwater mountain range located where tectonic plates are spreading apart. A rise is also known as a mid-ocean ridge.

What is the name of the mountain chains found underwater explain how they are formed?

A mid-ocean ridge or mid-oceanic ridge is an underwater mountain range, formed by plate tectonics. This uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent boundary.

What term best describes a long chain of underwater mountains?

The ocean floor has mountain chains that are as impressive as those on land. What are these underwater mountain chains called? Mid-ocean ridges.

Why is the Atlantic Ocean expanding?

Atlantic ocean is expanding due to formation of new crust at the mid-Atlantic ridge and westward motion of the North American Plate. Further Eurasian Plate is moving eastward and sliding over Pacific Plate and minor plates sinking in the Pacific ocean.

Which of the following increases with distance from a mid-ocean ridge?

The age, density, and thickness of oceanic crust increases with distance from the mid-ocean ridge.

Which is the most extensive chain of mountains on Earth?

The Mid-Ocean Ridge system forms the most extensive chain of mountains on Earth, with more than 90 percent of the mountain range lying in the deep ocean. The nearly continuous, global Mid-Ocean Ridge system snakes across the Earth’s surface like the seam on a baseball.

How big is the mid ocean ridge mountain range?

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 in the deep ocean.

Which is the longest mountain range in the world?

The nearly continuous, global mid-ocean ridge system snakes across the Earth’s surface like the seams on a baseball. It is clearly visible on this map of global topography above and below sea level. The ridge system forms the longest and largest mountain range on Earth, winding its way between the continents.

What causes the mid ocean ridge to form?

Mid-ocean ridges occur along divergent plate boundaries, where new ocean floor is created as the Earth’s tectonic plates spread apart. As the plates separate, molten rock rises to the seafloor, producing enormous volcanic eruptions of basalt. The speed of spreading affects the shape of a ridge – slower spreading rates result in steep,
