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 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 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
.
What are divergent boundaries and what do they create?
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.
What are divergent boundaries responsible for?
Divergent (Spreading):This is where
two plates move away from each other
. Molten rock from the mantle erupts along the opening, forming new crust. The earthquakes that occur along these zones, called spreading centers, are relatively small.
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
.
In which two places do divergent boundaries occur?
Divergent boundaries are typified in the oceanic lithosphere by the rifts of the oceanic ridge system, including
the Mid-Atlantic Ridge and the East Pacific Rise
, and in the continental lithosphere by rift valleys such as the famous East African Great Rift Valley.
Do divergent boundaries cause volcanoes?
Most volcanoes form at the boundaries of Earth’s tectonic plates. … The two types of plate boundaries that are most likely to produce volcanic activity are divergent plate boundaries and convergent plate boundaries.
What is another name for Transform boundaries?
A transform fault or transform boundary, sometimes called
a strike-slip boundary
, is a fault along a plate boundary where the motion is predominantly horizontal.
Do convergent boundaries cause volcanoes?
Destructive, or convergent, plate boundaries are where the tectonic plates are moving towards each other. Volcanoes form here in two settings where either oceanic plate descends below another oceanic plate or an oceanic plate descends below a continental plate.
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.
Which of the following best describes divergent boundaries?
Which of the following best describes what happens at a divergent plate boundary?
The plates separate from each other creating new crust in the process
. … Neither plate is subducted; instead, both are lifted up forming a mountain range.
What are examples of transform boundaries?
Some transform plate boundaries pass through continental crust. An example of such a transform is
the San Andreas Fault
. Along the San Andreas Fault the Pacific plate moves in a northwest direction relative to the North American plate.
Why do earthquakes occur on conservative plate boundaries?
A conservative plate boundary, sometimes called a transform plate margin, occurs where plates slide past each other in opposite directions, or in the same direction but at different speeds. Friction is eventually overcome and the plates slip past in a sudden movement.
The shockwaves created produce an earthquake
.
Can divergent boundaries cause earthquakes?
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 the difference between convergent and divergent plate boundaries?
Divergent boundaries
— where new crust is generated as the plates pull away from each other
. Convergent boundaries — where crust is destroyed as one plate dives under another.
