Plate Tectonics

____% of earthquakes happen along the ring of fire

• 90

• 75

• 50

• 25

Answer explanation

Approximately 90% of earthquakes occur along the Ring of Fire, which is a major area in the Pacific Ocean basin known for its high seismic activity. This makes 90 the correct answer.

The (a)   is the most famous transform boundary in the world

• San Andreas fault

• Hayward fault

• New Madrid seismic zone

• Cascadia Subduction Zone

Answer explanation

The San Andreas fault is the most well-known transform boundary, located in California. It is famous for its significant seismic activity and has been the focus of many studies on earthquakes.

The (a)   is responsible for the ring of fire.

• Pacific Plate

• Indian Plate

• American Plate

• African Plate

• Eurasian Plate

Answer explanation

The Pacific Plate is primarily responsible for the Ring of Fire, a region known for its high volcanic and seismic activity, due to its tectonic boundaries with several other plates.

A large wave formed from an earthquake under the ocean is called a (a)  

• tsunami

• aftershock

• shaking

• liquefaction

Answer explanation

A large wave caused by an underwater earthquake is known as a tsunami. The other options, such as aftershock and liquefaction, refer to different seismic phenomena and do not describe the wave itself.
