Most seismic activity occurs at three types of plate boundaries—divergent, convergent, and transform.
What are the 2 divergent boundaries?
There are two types of divergent boundaries, categorized by where they occur: continental rift zones and mid-ocean ridges.
What are 2 examples of divergent plates movement?
There are two major types of divergent boundaries. Continental and continental lithosphere and oceanic and oceanic lithosphere. An example of an oceanic and oceanic divergent boundary is the mid-ocean ridge. The mid-ocean ridge runs around the world including going right through Ice land.
Where are divergent plate boundaries on Earth?
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).
Do divergent plate boundaries create volcanoes?
Volcanoes are most common in these geologically active boundaries. The two types of plate boundaries that are most likely to produce volcanic activity are divergent plate boundaries and convergent plate boundaries.
What is divergent boundary class 9?
Complete answer: Divergent boundary is a linear feature in the theory of plate tectonics that takes place between two tectonic plates when they pull away from each other. This occurs due to the rise in convection currents.
What are 3 pairs of plates with divergent boundaries?
Divergent boundaries
The East African Rift (Great Rift Valley) in eastern Africa.The Mid-Atlantic Ridge system separates the North American Plate and South American Plate in the west from the Eurasian Plate and African Plate in the east.The Gakkel Ridge is a slow spreading ridge located in the Arctic Ocean.
What is an example of a convergent boundary?
Examples. The collision between the Eurasian Plate and the Indian Plate that is forming the Himalayas. Subduction of the northern part of the Pacific Plate and the NW North American Plate that is forming the Aleutian Islands. Subduction of the Nazca Plate beneath the South American Plate to form the Andes.
What is a real life example of a transform boundary?
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.
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.
Which of the following is the best example of divergent boundaries?
Examples of Divergent Boundaries
The mid-Atlantic ridge is an example of a divergent boundary, where the Eurasian Plate that covers all of Europe separates from the North American Plate. This underwater mountain range is constantly growing as new crust is formed.
What do you mean by divergent boundary?
[ dĭ-vûr′jənt ] A tectonic boundary where two plates are moving away from each other and new crust is forming from magma that rises to the Earth’s surface between the two plates.
Are divergent boundaries continental or oceanic?
Divergent boundaries exist where tectonic plates move apart from each other. Unlike convergent boundaries, divergence occurs between only oceanic or only continental plates, not one of each.
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 kind of plate boundary is the North American Plate?
The North American Plate has a transform boundary with the Pacific Plate, dividing California at the San Andreas Fault.
Which features are associated with divergent boundaries?
Most divergent plate boundaries are underwater and form submarine mountain ranges called oceanic spreading ridges. While the process of forming these mountain ranges is volcanic, volcanoes and earthquakes along oceanic spreading ridges are not as violent as they are at convergent plate boundaries.
