Earthquakes and Plate Tectonics

Front

What is the composition of the continental crust compared to the oceanic crust?

Back

The continental crust is made of granite and is less dense than the oceanic crust.

Front

What type of boundary occurs when two tectonic plates slide past each other?

Back

A Slide/Transform boundary.

Front

What type of seismic waves can travel through liquids?

Back

Only P waves can travel through liquids.

Front

Can P waves travel through the Earth's inner core?

Back

Yes, only P waves can travel through the inner core.

Front

How does the thickness of the continental crust compare to the oceanic crust?

Back

The continental crust is thicker and less dense than the oceanic crust.

Front

What are tectonic plates?

Back

Tectonic plates are large sections of the Earth's lithosphere that move and interact at their boundaries.

Front

What is a divergent boundary?

Back

A divergent boundary is where two tectonic plates move away from each other, often creating new crust.

Front

What is a convergent boundary?

Back

A convergent boundary is where two tectonic plates collide, leading to subduction or mountain formation.

Front

What are S waves?

Back

S waves, or secondary waves, are seismic waves that can only travel through solids.

Front

What is the difference between the oceanic crust and continental crust in terms of density?

Back

The oceanic crust is denser than the continental crust.
