Which is the place where two plates move apart?
divergent boundary the place where two plates move apart or divide. Mostly occurred at a mid-ocean ridge. On land, it forms a deep valley called rift valley. convergent boundary
What happens when two plates diverge under the ocean?
New plates form at tectonic boundaries that are diverging. At these boundaries, usually under the ocean, two plates pull apart and magma wells up and hardens, forming new rock and crust. The movement of one plate under another and the recycling of rock into magma can lead to some exciting geologic activity.
Where do the most divergent plates pull apart?
Divergent plate tectonics pull apart from each other producing rift valleys at mid-oceanic ridges. Most divergent plates are at oceanic plate boundaries. This is where long chains of underwater volcanoes spew out lava. And it turns out, these mid-oceanic ridges (rift valleys) has the youngest geologic rocks on the planet.

What are two plates that are tearing apart?
AFRICAN PLATE: The African Plate is in the process of rifting apart into two separate plates where it will become ocean. In addition, the Somalian and Nubian plates will one day tear apart and become new ocean. RED SEA: Between Asia and Africa, the Red Sea is spreading apart from the African and Arabian Plates.

What happens when two plates move apart in the ocean?
Divergent Plate Boundaries. Plates move apart at mid-ocean ridges where new seafloor forms. Between the two plates is a rift valley. Lava flows at the surface cool rapidly to become basalt, but deeper in the crust, magma cools more slowly to form gabbro.
Where does a divergent plate boundary occur in the ocean?
Divergent plate boundaries are locations where plates are moving away from one another. This occurs above rising convection currents. When a divergent boundary occurs beneath oceanic lithosphere, the rising convection current below lifts the lithosphere, producing a mid-ocean ridge.
What happens when plates of the mantle pull apart?
As plates made of oceanic crust pull apart, a crack in the ocean floor appears. Magma then oozes up from the mantle to fill in the space between the plates, forming a raised ridge called a mid-ocean ridge. The magma also spreads outward, forming new ocean floor and new oceanic crust.
What kind of tectonic plates are under the Atlantic Ocean?
