When two continental plates diverge,
a valleylike rift develops
. This rift is a dropped zone where the plates are pulling apart. As the crust widens and thins, valleys form in and around the area, as do volcanoes, which may become increasingly active.
What will form when plates boundaries diverge at land?
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 forms when two continental plates diverge group of answer choices?
For example, when two continental plates diverge from each other,
an ocean basin
is created due to the separation of land. On the other hand, if two oceanic plates diverged, a mid ocean ridge would form, which is also known as a spreading center.
Which of the following is the result of the divergent boundary between continental plates?
Divergent Plate Boundary – Continental
As the two plates pull apart, normal faults develop on both sides of the rift, and the central blocks slide downwards.
Earthquakes
occur as a result of this fracturing and movement. … This will produce a narrow, shallow sea within the rift.
What happens when two continental crust collide?
Plates Collide When two plates carrying continents collide, the continental crust buckles and rocks pile up,
creating towering mountain ranges
. … Plates Slide Past One Another Plates grinding past each other in opposite directions create faults called transform faults.
Which is the best example of a convergent plate boundary?
Answer:
The Washington-Oregon coastline of the United States
is an example of this type of convergent plate boundary. Here the Juan de Fuca oceanic plate is subducting beneath the westward-moving North American continental plate. The Cascade Mountain Range is a line of volcanoes above the melting oceanic plate.
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 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.
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.
Which of the following is an example of a continental continental divergent plate boundary?
Iceland
is an example of a country undergoing a continental divergent boundary. The Mid-Atlantic Ridge divides Iceland and is the boundary between the North American and Eurasian tectonic plates.
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 would be found at a divergent boundary?
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.
Why is there no subduction when two continental plates collide?
When two continental plates collide
neither plate can be subducted due to their high bouyancy
. With this type of collision there are no features such as a subduction zone, trench or acretionary wedge. … After collision the oceanic lithosphere breaks off and sinks into the mantle.
Where is an example of a continental continental plate boundary?
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 will happen when oceanic and continental crust collide?
When they collide,
the Oceanic crust sinks below the continent
. … Some of this crust joins the mantle, but lighter materials will rise up through the continent to emerge on the surface as volcanoes, melting some continental crust with it on the way up.
Which of the following is an example of an oceanic continental convergent plate boundary?
Examples of ocean-continent convergent boundaries are
subduction of the Nazca Plate under South America
(which has created the Andes Mountains and the Peru Trench) and subduction of the Juan de Fuca Plate under North America (creating the Cascade Range).
