What evidence do scientists use to determine that the outer core of the Earth is liquid?

What are the two main types of seismic waves?

Back

P-waves and S-waves

What is the primary cause of earthquakes?

Back

The movement of tectonic plates.

What is the difference between P-waves and S-waves in terms of their movement through materials?

Back

P-waves can move through solids, liquids, and gases; S-waves can only move through solids.

What is a transform plate boundary?

Back

A boundary where two tectonic plates slide past each other.
