Which type of event often occurs along transform fault boundaries?
A
volcanoes
B
earthquakes
C
sea-floor spreading
D
mountain building
Explanation: 

Detailed explanation-1: -The grinding action between the plates at a transform plate boundary results in shallow earthquakes, large lateral displacement of rock, and a broad zone of crustal deformation.

Detailed explanation-2: -Earthquakes are common at these boundaries, as stress builds up and is then released in a sudden jolt of energy. At transform boundaries, two plates slide past each other horizontally. This motion creates energy that is released in the form of earthquakes.

Detailed explanation-3: -Transform boundaries typically produce large, shallow-focus earthquakes. Although earthquakes do occur in the central regions of plates, these regions do not usually have large earthquakes.

Detailed explanation-4: -The most common feature at transform boundaries are linear valleys or broken stream beds. They are a common location for earthquakes. As the crust moves horizontally against another plate, friction occurs. Eventually, the energy will be released in the form on an earthquake.

Detailed explanation-5: -Shallow earthquakes are also common along transform boundaries, such as the San Andreas Fault. Of course earthquakes also occur at convergent boundaries, whether they involve continental or oceanic crust. Along subduction zones, as oceanic crust descends, earthquakes are very abundant.
