Question

the waves used to study earths deep internal structure is (are)○ l and b waves○ s waves○ b waves○ l waves○ p waves○ both p and s wavesquestion 5 (1 point)which type of wave arrives at any seismographic station first?○ b waves○ surface waves○ q waves○ s waves○ p wavesquestion 6 (1 point)which important characteristic distinguishes the two types of body waves?○ p waves do not travel through rock○ none of these answers are correct○ s waves travel through gases○ s waves move faster than p waves○ s waves do not travel through liquids○ s waves travel through liquids

Explanation:

1. For the first question: P waves can travel through solid, liquid, and gaseous materials in Earth's interior, while S waves can only travel through solids. By studying how both waves propagate and are detected, scientists can map Earth's deep internal structure (like the liquid outer core identified by S wave shadow zones).
2. For Question 5: P waves are the fastest seismic body waves, so they reach seismographic stations before all other seismic waves.
3. For Question 6: The key difference between P (primary) and S (secondary) body waves is that S waves cannot travel through liquid materials, while P waves can.

Answer:

1. both P and S waves
2. P waves
3. S waves do not travel through liquids
