Plate Tectonics: Vital Facts

3. What are the boundaries that can cause earthquakes?

Convergent boundaries are responsible for earthquake formation.

4. What boundaries can result in volcanoes?

Convergent boundaries are also responsible for the formation of composite volcanoes.

5. At which of the following borders is a sea floor formed?

The obduction zones, also known as the sea floor spreading, are responsible for the formation of the sea floor. They are the outcome of divergent borders.

6. Which of the following boundaries destroys a sea floor?

The devastation of the seafloor occurs as a result of subduction at deep marine trenches. This process occurs at convergent borders.

7. What are the three types of plate boundaries that converge?

Oceanic-oceanic boundary

Oceanic-continental boundary

Continental-continental boundary

8. What volcanic island sits on top of the Mid-Atlantic Ridge?

Iceland

9. The boundary between the Eurasian Plate and the Indo-Australian Plate at the Himalaya Mountains is an example of which boundary?

Continental-continental boundary

10. Which type of plate boundary occurs between the Pacific and Antarctic Plates?

Oceanic-continental boundary

The interaction of the North American Plate and the Pacific Plate in California is an example of which type of plate interaction?

This zone forms a transform boundary at which the plates slide along each other.

The Mid-Atlantic Ridge, made up of the boundary between the North Atlantic and Pacific Plates in the North Atlantic, cutting through Iceland is an example of which type of plate boundary?

This type of boundary is referred to as the divergent/spreading boundary.

Which type of plate boundary occurs in the South Atlantic Ocean, between the South American and African Plates?

The transform boundary exists between the South American and African Plates.

The Red Sea is an example of which type of plate boundary? Which two plates are involved?

The Red Sea falls between the African and Arabian Plates, being a spreading center in between, having been formed by divergent forces.

New Zealand is largely the result of which type of plate interaction? Which two plates are involved?

New Zealand is a product of convergence of the Australian and Pacific Plates.
