What is a mid-ocean ridge simple definition?

What is a mid-ocean ridge simple definition?

ˈmid-ˈō-shən- : an elevated region with a central valley on an ocean floor at the boundary between two diverging tectonic plates where new crust forms from upwelling magma.

What is in the mid-oceanic ridge?

The massive mid-ocean ridge system is a continuous range of underwater volcanoes that wraps around the globe like seams on a baseball, stretching nearly 65,000 kilometers (40,390 miles). The majority of the system is underwater, with an average water depth to the top of the ridge of 2,500 meters (8,200 feet).

Where is the mid-ocean ridge?

The mid ocean ridge systems are the largest geological features on the planet. The Mid-Atlantic Ridge (MAR) is a mostly underwater mountain range in the Atlantic Ocean that runs from 87°N -about 333km south of the North Pole- to subantarctic Bourvet island at 54°S.

What is mid-oceanic ridge class 11?

The line or boundary that separates the water from the land is called mid-oceanic ridge.

What is mid oceanic ridge upsc?

A mid-oceanic ridge is an underwater mountain range, formed by plate tectonics. It is composed of two chains of mountains divided by a large depression. The mountain ranges can have peaks as high as 2,500 m and some even reach above the ocean’s surface.

What is the mid-ocean ridge Why is it important?

Mid-ocean ridges are geologically important because they occur along the kind of plate boundary where new ocean floor is created as the plates spread apart. Thus the mid-ocean ridge is also known as a “spreading center” or a “divergent plate boundary.” The plates spread apart at rates of 1 cm to 20 cm per year.

What are the 3 types of mid-ocean ridges?

• Axial Ridge.
• Magnetics & Polarity.
• Fast/Slow Spreading.

• Magnetics & Polarity.
• Fast/Slow Spreading.

What plates make up the mid-ocean ridge?

This ridge is formed as the North American and Eurasian plates, as well as the South American and African plates, move away from each other. The Mid-Atlantic Ridge is considered a slow-spreading center, with 2 to 5 centimeters, or 0.8 to 2 inches, of new ocean floor formed each year.

What is a mid-ocean ridge for kids?

The mid-ocean ridge is formed where two tectonic plates meet under the ocean. This divergent boundary creates mountains, valleys like the famous rift valley, volcanoes, and sometimes earthquakes. It stretches all around the Earth, is home to many strange animals, and still has a lot to be explored.

What are some examples of mid-ocean ridges?

5. What are examples of Mid Ocean-Ridges? Some examples include- the Mid-Indian Ocean Ridge, Carlsberg Ridge, Pacific-Antarctic Ridge, and the East Pacific Rise.

When was the mid-ocean ridge discovered?

It is now called the Mid-Ocean Ridge. In 1953, American physicists Maurice Ewing (1906-1974) and Bruce Heezen (1924-1977) discovered that through this underwater mountain range ran a deep canyon.

What is another name for the mid-oceanic ridge?

A divergent boundary within an oceanic plate, where new lithosphere and crust is created as the two plates spread apart. Mid-ocean ridge and spreading center are synonyms.

What is Mid-Atlantic Ridge Class 6?

The Mid-Atlantic Ridge is a mountain range submerged in the northern part of the Atlantic Ocean. It is the longest mountain range in the world.

What is difference between oceanic ridge and mid-oceanic ridge?

Oceanic ridges are mountain ranges that have developed underwater. At the divergent plate boundary, the seafloor stretches along with the mid-ocean range. The seafloor spreads differently around the mid-ocean slope. Oceanic rises are the sections of the mid-ocean ridge that spread out quickly and have a gentle slope.
