Question

select the correct responses to the questions from the drop - down menus. which type of wave vibrates both side to side and up and down? which type of wave is the first to arrive during an earthquake? which type of wave may make the ground roll?

Explanation:

1. S - waves (secondary waves) vibrate both side - to - side and up - and - down. They are shear waves.
2. P - waves (primary waves) are the first to arrive during an earthquake as they are compressional waves and travel the fastest through the Earth's interior.
3. Surface waves may make the ground roll. They move more slowly than P and S waves but cause more damage due to their larger amplitude.

Answer:

1. S wave
2. P wave
3. surface wave
