Question

what does the graph show?
the s and p waves travel the same distance through earths crust in the same amount of time.
the p wave travels through earths crust more quickly than the s wave travels.
it takes the p wave 18 minutes to travel 6,000 km through earths crust.
it takes the s wave 11 minutes to travel 8,000 km through earths crust.

Explanation:

1. For any given distance (e.g., 6,000 km), the P wave has a shorter travel time (~10 minutes) than the S wave (~18 minutes).
2. For any given travel time, the P wave covers a greater distance than the S wave.
3. Evaluating other options:

• The first option is false, as travel times differ for the same distance.
• The third option is false: the P wave takes ~10 minutes for 6,000 km.
• The fourth option is false: the S wave takes ~20 minutes for 8,000 km.

Answer:

The P wave travels through Earth's crust more quickly than the S wave travels.
