Where is a mid-ocean ridge?
As tectonic plates move away from one another at mid-ocean ridges, molten rock from the mantle may well up and harden as it contacts the frigid sea, forming new oceanic crust at the bottom of the rift valley. ... Over millions of years, the Mid-Atlantic Ridge has formed rift valleys as wide as 15 kilometers (9 miles).
Where is the Rift Valley?
The Rift Valley, located in Eastern Africa, covers just over 2% of the continent and spreads over seven countries (Map 5 and Table 29). min. max. 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.
Is a rift valley the same as a mid-ocean ridge?
Continental rift zones occur in weak spots in the continental lithospheric plate. A mid-ocean ridge usually originates in a continental plate as a rift zone that expands to the point of splitting the plate apart, with seawater filling in the gap.Feb 14, 2021
Where is the Rift Valley in the Mid Atlantic Ridge?
The Mid-Atlantic Ridge is a giant rift valley that runs along the Atlantic Ocean floor from north to south. It was formed by tectonic forces and diverging plates. As the Eurasian and North American plates move apart, rising magma solidifies and creates new oceanic crust along the rift valley.Sep 22, 2021
Where is rift valley located in India?

Which is a rift valley?
A rift valley is a lowland region formed by the interaction of Earth's tectonic plates. ... A rift valley is a lowland region that forms where Earth's tectonic plates move apart, or rift. Rift valleys are found both on land and at the bottom of the ocean, where they are created by the process of seafloor spreading.Jun 15, 2015
What is the difference between a trench and a rift valley?
This rift marks the actual boundary between adjacent tectonic plates, where magma from the mantle reaches the seafloor, erupting as lava and producing new crustal material for the plates. As per Wikipedia: a rift valley is a type of trench!
Is a rift valley convergent or divergent?
Areas where plates are colliding form convergent boundaries, and areas where plates are expanding create divergent boundaries. Rift valleys are formed by divergent boundaries that involve continental plates.Apr 24, 2017
Why is the Great Rift Valley important?
The Rift Valley has been a rich source of fossils that allow study of human evolution, especially in an area known as Piedmont. Because the rapidly eroding highlands have filled the valley with sediments, a favourable environment for the preservation of remains has been created.
Where is the mid-Atlantic Ocean?
The Mid-Atlantic Ridge extends from south of Iceland to the extreme South Atlantic Ocean near 60° S latitude. It bisects the Atlantic Ocean basin, which led to the earlier designation of mid-ocean ridge for features of this type.Nov 22, 2021

What is rift valley in India?
It is one of the rivers in India that flows in a rift valley, bordered by the Satpura and Vindhya ranges. As a rift valley river, the Narmada does not form a delta; Rift valley rivers form estuaries. The other rivers which flow through rift valley include Damodar River in Chota Nagpur Plateau and Tapti.
What is an example of a mid - ocean ridge?
- Mid Oceanic Ridge forms According to Sea Floor Spreading theory of Harry Hess , The lava get splinted apart and a ridge located at Divergent tectonic plate or constructive plate boundary. The Most Famous example is Mid-Oceanic Ridge of Atlantic Ocean which consist of the Dolphin ridge in north and Challenger ridge in southern part.
Where are mid - ocean ridges located?
- The Mid-Atlantic Ridge (MAR) is a mid-ocean ridge, a divergent tectonic plate or constructive plate boundary located along the floor of the Atlantic Ocean, and part of the longest mountain range in the world.
How rift valleys are formed?
- A rift valley is formed on a divergent plate boundary, a crustal extension or spreading apart of the surface, which is subsequently further deepened by the forces of erosion.
What plate boundary formed the Mid - Atlantic Ridge?
- Mid-Atlantic Ridge. The Mid-Atlantic Ridge (MAR) is a mid-ocean ridge, a divergent tectonic plate or constructive plate boundary located along the floor of the Atlantic Ocean, and part of the longest mountain range in the world.
