What Landscape Forms At A Mid Ocean Ridge?

Answer:

mid-ocean ridge | AMNH. When viewed from above, the wide-open sea is vast and flat. But venture below and you’ll find a varied landscape that includes the deepest valleys and tallest mountains on Earth. These underwater mountains, or mid-ocean ridges, are formed from volcanic activity.

Answer:

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.

Frequently Asked Questions

What forms at a mid-ocean ridge?

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.

What is most likely to form at a mid-ocean ridge?

Answer: The answer is: volcano. Explanation: The mid-ocean ridges are underwater elevations located in the middle part of the Earth's oceans.

What type of boundary does a mid-ocean ridge form upon?

divergent boundaryA 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 do you expect to find at a mid-ocean ridge answer?

Answer Expert Verified The relatively young rocks will be found at the mid-ocean ridge.

What are the features of the mid oceanic ridge?

Tectonic extension and volcanic eruptions are the most common features of Mid oceanic ridge. On the flanks of Mid oceanic ridges, certain fissures are also present. Away from the axis of mid oceanic ridge, the oceanic crust cools down and becomes stable. It is known as a “plate boundary zone”.

How is the mid ocean ridge similar to a baseball?

Mid-ocean ridges around the globe are linked by plate tectonic boundaries and the trace of the ridges across the ocean floor appears similar to the seam of a baseball. The mid-ocean ridge system thus is the longest mountain range on Earth, reaching about 65,000 km (40,000 mi).

How is oceanic lithosphere formed at mid ocean ridge?

Oceanic lithosphere is formed at an oceanic ridge, while the lithosphere is subducted back into the asthenosphere at ocean trenches. Two processes, ridge-push and slab pull, are thought to be responsible for spreading at mid-ocean ridges.

What is the spreading rate of the mid ocean ridge?

The rate at which the mid-ocean ridge creates new material is known as the spreading rate, and is typically measured in mm/yr. As a general rule, fast ridges have spreading (opening) rates of more than 90 mm/year. Intermediate ridges have a spreading rate of 40–90 mm/year while slow spreading ridges have a rate less than 40 mm/year.
