Seismic Activity and Plate Tectonics Quiz

What does the size of the circle in the earthquake simulation represent?

• The depth of the earthquake

• The magnitude of the earthquake

• The location of the earthquake

• The duration of the earthquake

Where do earthquakes most commonly occur on Earth's surface?

• In the middle of tectonic plates

• At the boundaries between tectonic plates

• Randomly across the Earth's surface

• Only in oceanic regions

What are lithospheric plates?

• Solid slabs of rock that make up Earth's surface

• Liquid layers beneath the Earth's crust

• Gaseous layers surrounding the Earth

• Magnetic fields around the Earth

Which type of plate boundary involves plates moving apart?

• Transform boundary

• Divergent boundary

• Convergent boundary

• Static boundary

What happens at a convergent boundary?

• Plates remain stationary

• Plates collide with each other

• Plates slide past each other

• Plates move apart

What is a characteristic of earthquakes at the Mid-Atlantic Ridge?

• They are very deep

• They are very shallow

• They occur randomly

• They are extremely rare

What type of boundary is the San Andreas Fault an example of?

• Subduction zone

• Transform boundary

• Divergent boundary

• Convergent boundary

In a transform boundary, how do the plates move?

• They collide with each other

• They move apart

• They slide past each other

• They subduct beneath each other

What is the result of continental to continental collision in the Himalayas?

• Development of volcanic islands

• Creation of the Himalaya Mountains

• Emergence of new tectonic plates

• Formation of deep ocean trenches

Why are earthquakes in the Himalayas not as deep as those in subduction zones?

• Because there is no subduction occurring

• Because the plates are moving apart

• Because the region is inactive

• Because the plates are sliding past each other
