Divergent (Spreading):This is
where two plates move away from each other
. Molten rock from the mantle erupts along the opening, forming new crust. … Sometimes the molten rock rises to the surface, through the continent, forming a line of volcanoes.
What is an example of a divergent?
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.
What is divergent movement in geography?
At divergent boundaries in the oceans,
magma from deep in the Earth’s mantle rises toward the surface and pushes apart two or more plates
. Mountains and volcanoes rise along the seam. The process renews the ocean floor and widens the giant basins.
What is formed in divergent plate movement?
When two plates are moving away from each other, we call this a divergent plate boundary. Along these boundaries, magma rises from deep within the Earth and
erupts to form new crust on the lithosphere
. Most divergent plate boundaries are underwater and form submarine mountain ranges called oceanic spreading ridges.
What is the difference between convergent and divergent movement?
| Converging tectonic plates Diverging tectonic plates | They form a convergent boundary. They form divergent boundaries. | These plates form mountains. These spread over the ocean floor. |

What landforms are created by divergent boundaries?
At DIVERGENT boundaries the plates move apart allowing molten magma to rise and form new crust in the form of ridges, valleys and volcanoes. Landforms created by divergent plates include
the Mid Atlantic Ridge and the Great African Rift Valley
.
What are the examples of divergent boundary?
- Mid-Atlantic Ridge.
- Red Sea Rift.
- Baikal Rift Zone.
- East African Rift.
- East Pacific Rise.
- Gakkel Ridge.
- Galapagos Rise.
- Explorer Ridge.
What is an example of divergent evolution?
Galapagos finches
are an example of divergent evolution. Through time, the species evolved morphologically different traits. A prototype example of divergent evolution is Galapagos finches. … Thus, they become a different species to their ancestors and what was once one species has diverged into two.
What are two 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
.
Which of the following is the best example of divergent boundaries?
Perhaps the best known of the divergent boundaries is
the Mid-Atlantic Ridge
. This submerged mountain range, which extends from the Arctic Ocean to beyond the southern tip of Africa, is but one segment of the global mid-ocean ridge system that encircles the Earth.
What are the 4 types of plate tectonics?
- Divergent: extensional; the plates move apart. Spreading ridges, basin-range.
- Convergent: compressional; plates move toward each other. Includes: Subduction zones and mountain building.
- Transform: shearing; plates slide past each other. Strike-slip motion.
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.
Do earthquakes occur at divergent plate boundaries?
Divergent boundaries are
associated with volcanic activity
and the earthquakes in these zones tend to be frequent and small. Continental collisions result in the creation of mountains and fold belts as the rocks are forced upwards. Plates can move towards each other at a boundary.
What is convergent 9th plate?
Convergent boundaries occur
where two plates slide toward each other to form
either a subduction zone (one plate moving underneath the other) or a continental collision. Continent-to-continent boundaries are regions where two continental convergent plates are colliding leading.
What are the three types of convergent boundaries?
Convergent boundaries , where two plates are moving toward each other, are of three types, depending on the type of crust present on either side of the boundary — oceanic or continental . The types are
ocean-ocean, ocean-continent, and continent-continent.
What are the similarities between convergent and divergent boundaries?
The similarities are that a boundary of any kind marks the line between two tectonic plates. Similarities between divergent and convergent boundaries include
magma or lava flows, formation of new topographic features and re-shaping of landmasses
.
