Why does the speed of the waves change so much when they reach the outer core?

• The outer core is liquid.

• The outer core is colder.

• The outer core is angry.

• The outer core is less dense.

What happens to the path of waves when they REFLECT?

• Their path bends and continues moving forward.

• Their path bounces back.

• Their path continues the same way it was.

Why do waves reflect and refract?

• They just randomly change paths.

• They meet a medium with a new density.

• They get faster.
