Where is the newest mid ocean ridge system forming?

Scientists Report New Type of Mid-Ocean Ridge in Remote Parts of the Earth. Scientists from the Woods Hole Oceanographic Institution (WHOI) have identified a new type of ocean ridge that is spreading so slowly that Earth’s mantle is exposed over large regions of the sea floor.

Where is a mid-ocean ridge most likely to form?

Mid-ocean ridges occur along divergent plate boundaries, where new ocean floor is created as the Earth’s tectonic plates spread apart.

Where is the youngest mid-ocean ridge?

1) mid ocean ridge A mid-ocean ridge forms whenever diverging plates continue to separate, creating a new ocean basin as the rising magma cools. The youngest rocks on the ocean floor are located here. The Mid-Atlantic Ridge, a Mid Ocean Ridge, is part of a divergent plate boundary.

Why is the mid-ocean ridge the youngest most recent area formed?

The divergent boundaries are the areas where plates are moving apart from one another. Where plates move apart, new crustal material is formed from molten magma from below the Earth’s surface. Because of this, the youngest sea floor can be found along divergent boundaries, such as the Mid-Atlantic Ocean Ridge.

Where are the newest and oldest crust found with the mid-ocean ridge?

The new crust is then pushed away from the ridge as newer crust comes to the surface. The ocean crust then spreads out enlarging the ocean. The farer away from the ridge the ocean crust is the older the crust is. The oldest crust is at edges of the ocean.

Where is the youngest part of the ocean floor?

mid-ocean ridges

The youngest crust of the ocean floor can be found near the seafloor spreading centers or mid-ocean ridges. As the plates split apart, magma rises from below the Earth’s surface to fill in the empty void.

How is the mid-ocean ridge formed?

It formed and evolves as a result of spreading in Earth’s lithosphere—the crust and upper mantle—at the divergent boundaries between tectonic plates. The vast majority of volcanic activity on the planet occurs along the mid-ocean ridge, and it is the place where the crust of the Earth is born.

Where is the Mid-Atlantic Ridge located?

the Atlantic Ocean

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 led to the discovery of mid-ocean ridges?

Development of highly sophisticated seismic recorders and precision depth recorders in the 1950s led to the discovery in the early 1960s that the Mid-Atlantic Ridge, a vast, sinuous undersea mountain chain bisecting the Atlantic Ocean, was in fact only a small segment of a globe-girdling undersea mountain system some …

What is fractionated plateau?

The fractioned plateau is the longest mountain chain on the earth’s surface which is submerged under the sea. It is characterized by a central rift system at the crest.

What is the longest mountain range on Earth either on land or under water?

The mid-ocean ridge

The mid-ocean ridge is the longest mountain range on Earth.
The longest mountain range on Earth is called the mid-ocean ridge. Spanning 40,389 miles around the globe, it’s truly a global landmark. About 90 percent of the mid-ocean ridge system is under the ocean.

Are there any places on Earth where the mid oceanic ridges meet the continent?

The place where the Mid-Atlantic Ridge is best visible is at Thingvellir National Park, in southwestern Iceland. The continental drift between the North American and Eurasian Plates can be clearly seen in the cracks or faults which traverse the region, the largest one, Almannagjá, being a veritable canyon.

What is the difference between Rift Valley and mid-ocean ridge?

The major difference between different types is what type of plate the divergent boundary is between. If the boundary is found between two continental plates you are left with a rift valley. … If two oceanic plates begin moving away from each other it creates a mid-oceanic ridge.

Where does rift valley start and end?

The Great Rift Valley is a series of contiguous geographic trenches, approximately 7,000 kilometres (4,300 mi) in total length, that runs from Lebanon in Asia to Mozambique in Southeast Africa.

How rift valley was formed?

Rift valleys form when tectonics plates beneath the Earth’s surface diverge (or move away from one another in opposite directions). It is important to note here that rift valley formation, unlike rivers and glacial valleys, are solely created as a result of tectonic plate movement.

Where is rift valley located?

The Rift Valley consists of a group of independent interior basins, extending from Djibouti in the north to Tanzania in the south, nearly half being located in Ethiopia.

Where is continental rifting occurring today?

Where is a place where continental rifting is occurring today? We begin with perhaps the best example of a modern continental rift zone – the East African Rift. The East African Rift is a high terrain, a broad upwarp of the continent.

Is the Great Rift Valley in Kenya?

Stretching from the Lebanon to Mozambique, Africa’s Great Rift Valley is a 6,000-mile crack in the earth’s crust, and much of it is to be found in Kenya, where it has literally cut the country in two. The Valley contains some of the world’s finest lakes, mountains and plains.

What is the difference between valley and rift valley?

Rift valleys are found both on land and at the bottom of the ocean, where they are created by the process of seafloor spreading. Rift valleys differ from river valleys and glacial valleys in that they are created by tectonic activity and not the process of erosion.

Which is the longest rift valley in the world?

The largest and deepest rift valley yet discovered is not on Earth—it’s on Mars. Valles Marineris was formed millions of years ago, when the rocky Martian lithosphere was still rifting and shifting. Valles Marineris reaches depths of up to 7 kilometers (4 miles) and spans about 4,000 kilometers (2,500 miles) long.

Why is the rift valley important to Africa?

The system of rift valleys that characterizes the African continent represents a perfect environment to understand the evolution of mankind; for the important paleoanthropological discoveries in Ethiopia, Kenya, Tanzania, Uganda and Zaire, the African rift valleys are indeed considered the “cradle of mankind”, that is …

How deep is the Great Rift valley?

The Great Rift Valley runs north to south for 5000 km, varies in width from 30-100 km, and is between several hundred to several thousand metres deep at any given point.

Where is Africa splitting apart?

The African continent is slowly separating into several large and small tectonic blocks along the diverging East African Rift System, continuing to Madagascar – the long island just off the coast of Southeast Africa – that itself will also break apart into smaller islands.

Is crack in Africa?

A large crack, stretching several kilometres, made a sudden appearance recently in south-western Kenya. The tear, which continues to grow, caused part of the Nairobi-Narok highway to collapse. Initially, the appearance of the crack was linked to tectonic activity along the East African Rift.

Which lake is found in the Great Rift valley?

The lakes are; Lake Elementaita (6,300 ha), Lake Nakuru (18,800ha) and Lake Bogoria (10,700ha) all of which lie in basins on the floor of the Great Rift Valley which transects Kenya North-South. All the three lakes are shallow, alkaline and are hydro-geologically connected through sub surface seepage of water.

Where is the crack in Kenya?

Part of a highway has collapsed after a crack opened up in Kenya’s Rift Valley. Several families have been evacuated from the Suswa area in the south-western part of the country.

How many plateaus are there in Kenya?

12 PLATEAUS

12 PLATEAUS AND MONOLITHS
Elevations run mainly between 300 and 900 meters (1,000 and 3,000 feet) except for the Chyulu Range and the Taita Hills, both of which rise to over 2,134 meters (7,000 feet).
