What is an example of a divergent plate boundary in Earth?
A divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries, earthquakes are common and magma (molten rock) rises from the Earth’s mantle to the surface, solidifying to create new oceanic crust. The Mid-Atlantic Ridge is an example of divergent plate boundaries.
Which is an example of divergent boundaries?
An example of a divergent boundary is the mid Atlantic Ridge (there are mid ocean ridges in the Indian, and Pacific Oceans as well). The Mid Atlantic Ridge creates volcanos where the hot magma erupts from the underlining mantle. Divergent boundaries also create Rift Valleys and new oceans.
What are 2 examples of divergent boundaries?
Examples
- Mid-Atlantic Ridge.
- Red Sea Rift.
- Baikal Rift Zone.
- East African Rift.
- East Pacific Rise.
- Gakkel Ridge.
- Galapagos Rise.
- Explorer Ridge.
Where do divergent boundaries occur?
Divergent boundaries. Divergent boundaries occur along spreading centers where plates are moving apart and new crust is created by magma pushing up from the mantle.
What are the 2 types of divergent boundaries?
At divergent boundaries, sometimes called constructive boundaries, lithospheric plates move away from each other. There are two types of divergent boundaries, categorized by where they occur: continental rift zones and mid-ocean ridges.
What is form in divergent boundaries?
A divergent plate boundary often forms a mountain chain known as a ridge. This feature forms as magma escapes into the space between the spreading tectonic plates.
What are 3 things that are formed at a divergent boundary?
Effects that are found at a divergent boundary between oceanic plates include: a submarine mountain range such as the Mid-Atlantic Ridge; volcanic activity in the form of fissure eruptions; shallow earthquake activity; creation of new seafloor and a widening ocean basin.
Is it safe to live near divergent boundaries?
Most of the hazards that characterize a divergent plate boundaries lie under the ocean but on land the hazards are faults, volcanoes , and the most obvious one; earthquakes. The history of any one part of the Earth, like the life of a soldier, consists of long periods of boredom and short periods of terror.
What happens when two oceanic plates collide?
A subduction zone is also generated when two oceanic plates collide — the older plate is forced under the younger one — and it leads to the formation of chains of volcanic islands known as island arcs. Earthquakes generated in a subduction zone can also give rise to tsunamis.
What are 2 examples of convergent boundaries?
Examples of continent-continent convergent boundaries are the collision of the India Plate with the Eurasian Plate, creating the Himalaya Mountains, and the collision of the African Plate with the Eurasian Plate, creating the series of ranges extending from the Alps in Europe to the Zagros Mountains in Iran.
What are some examples of divergent plates?
Some divergent plate boundary examples are the East Pacific rise (a fast spreading zone), the Mid-Atlantic ridge (a slow spreading zone), the Rift Valley of Africa. There are many others.
Where are the most divergent boundaries found?
Most modern divergent plate boundaries are found in the mid-ocean ridges. When rocks are hotter such that they are higher and less dense, they cause ridges in the ocean.
What landforms are formed at divergent plate boundaries?
Rising magma can also create shield volcanoes. Landforms at a divergent plate boundary include ocean ridges, eg the Mid-Atlantic ridge (where the Eurasian plate and the North Atlantic plate are moving apart from each other under the Atlantic Ocean), rift valleys eg the East African Rift Valley and shield volcanoes.
What forms when plates diverge?
As the name implies, divergent boundaries are formed when two adjacent tectonic plates separate, i.e., when they diverge. When tectonic plates start to diverge, the linear feature formed is called a rift. Sometimes, the gap widens and sometimes it stops. When the gap eventually widens, it then evolves into a rift valley .
