Question

example of locations where divergant boundarys form

Answer 1

I think you mean "divergent boundaries" (where tectonic plates move apart). Examples and where they form:

- Mid-Atlantic Ridge — runs down the middle of the Atlantic Ocean (separates the North American & Eurasian plates in the north and the South American & African plates in the south). Iceland sits on this ridge.
- East Pacific Rise — fast-spreading ridge in the eastern Pacific (between the Pacific Plate and Nazca/Cocos plates).
- Juan de Fuca Ridge — spreading center off the coast of Washington/Oregon (between the Juan de Fuca and Pacific plates).
- Gakkel Ridge — very slow-spreading ridge under the Arctic Ocean between the North American and Eurasian plates.
- East African Rift — continental rift in eastern Africa (Somali and Nubian parts of the African Plate are pulling apart; can evolve into a new ocean basin).
- Red Sea Rift — between the African and Arabian plates; an example of rifting that is becoming an ocean basin.
- Baikal Rift — continental rift in Siberia (Lake Baikal sits in the rift).

Typical features at divergent boundaries: rift valleys (on land), mid-ocean ridges, seafloor spreading, basaltic volcanism, frequent shallow earthquakes and hydrothermal vents.
