Do transform or convergent boundaries cause earthquakes?
Movement in narrow zones along plate boundaries causes most earthquakes. Most seismic activity occurs at three types of plate boundaries—divergent, convergent, and transform. As the plates move past each other, they sometimes get caught and pressure builds up. … Some of the plates have ocean water above them.
Which of the boundaries can produce earthquakes?
What type of boundaries can produce earthquakes? Both convergent and Transform boundaries can produce earthquakes.
Why does California have so many earthquakes?
The earthquakes of California are caused by the movement of huge blocks of the earth’s crust- the Pacific and North American plates. … Over time, these faults produce about half of the significant earthquakes of our region, as well as many minor earthquakes.
Why do earthquakes occur at transform boundaries?
When two plates are moving away from each other, we call this a divergent plate boundary. … This is known as a transform plate boundary. As the plates rub against each other, huge stresses can cause portions of the rock to break, resulting in earthquakes. Places where these breaks occur are called faults.
Why do convergent boundaries cause earthquakes?
Convergent plate boundaries
The plates move towards one another and this movement can cause earthquakes. … This happens because the oceanic plate is denser (heavier) than the continental plate. When the plate sinks into the mantle it melts to form magma. The pressure of the magma builds up beneath the Earth’s surface.
