how does the structure of earths interior affect seismic waves?
it can affect the speed and direction of seismic waves
it can send seismic waves into shadow zones and seismic gaps
it can change seismic waves into dangerous earthquakes

Explanation:

Seismic waves interact with Earth's interior layers. Different layers (like crust, mantle, core) have varying properties (density, composition). These properties cause seismic waves to refract (change direction) and their speed to alter. Shadow zones (areas where certain waves aren't detected) are due to wave - layer interactions. But seismic waves don't cause earthquakes (they are a result of earthquakes).

Answer:

it can affect the speed and direction of seismic waves
