Examples of divergent plates
What are the 3 divergent plates?
False, because the correct statement is: There are three types of divergent plate boundaries, namely continental-continental, oceanic-continental, and oceanic-oceanic.
What are 3 examples of plate boundaries?
Most seismic activity occurs at three types of plate boundaries—divergent, convergent, and transform.
What are the types of divergent plate?
There are two types of divergent boundaries, categorized by where they occur: continental rift zones and mid-ocean ridges. Continental rift zones occur in weak spots in the continental lithospheric plate.
Which of the following is an example of diverging plates?
An example of a divergent plate boundary is the Mid-Atlantic Ridge. Depending on what type of lithospheric crust each diverging plate is, whether oceanic or continental, varying geographic features are formed.
Which is the best example of a 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).
Where on earth can you find divergent boundaries?
mid-ocean oceanic ridges
Most divergent boundaries are located along mid-ocean oceanic ridges (although some are on land). The mid-ocean ridge system is a giant undersea mountain range, and is the largest geological feature on Earth; at 65,000 km long and about 1000 km wide, it covers 23% of Earth’s surface (Figure 4.5. 1).
What are 2 examples of divergent boundaries?
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.
Which is the best example of a divergent plate boundary?
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.
Is the Red Sea a divergent boundary?
The Arabian Plate is rifting away from the African plate along an active divergent ridge system, to form the Red Sea and Gulf of Aden.
What are 4 types of plate boundaries?

What are plate boundaries?
A plate boundary is a three-dimensional surface or zone across which there is a significant change in the velocity (speed or direction) of motion of one lithospheric plate relative to the adjacent lithospheric plate.
What are some examples of transform boundaries?
The San Andreas Fault and Queen Charlotte Fault are transform plate boundaries developing where the Pacific Plate moves northward past the North American Plate. The San Andreas Fault is just one of several faults that accommodate the transform motion between the Pacific and North American plates.
What is the 7 major plates?
There are major, minor and micro tectonic plates. There are seven major plates: African, Antarctic, Eurasian, Indo-Australian, North American, Pacific and South American.
What are the 7 minor plates?
Contexts in source publication. … Earth has seven large plates (Pacific, North American, South American, Eurasian, African, IndoAustralian, and Antarctic plates), seven smaller plates (Juan de Fuca, Caribbean, Cocos, Nazca, Scotia, Arabian, and Philippine plates), and several microplates (Figure 1; Bird, 2003).
What is formed at divergent plate boundaries?
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.
Are there 15 tectonic plates?
There are a total of seven major tectonic plates which cover nearly 95% of the Earth’s surface.
What type of plate is the African Plate?
major tectonic plate
The African Plate is a major tectonic plate straddling the Equator as well as the prime meridian. It includes much of the continent of Africa, as well as oceanic crust which lies between the continent and various surrounding ocean ridges.
What is the largest plate?
The largest plates are the Antarctic, Eurasian, and North American plates. Plates are on average 125km thick, reaching maximum thickness below mountain ranges. Oceanic plates (50-100km) are thinner than the continental plates (up to 200km) and even thinner at the ocean ridges where the temperatures are higher.
What are the 12 plate boundaries?
The Earth’s major tectonic plates are:
- African Plate.
- Antarctic Plate.
- Eurasian Plate.
- Australian Plate.
- North American Plate.
- Pacific Plate.
- South American Plate.
