Primary waves can move through liquids, solids, and gasses.

Primary waves travel to fewer places on Earth's surface.
Primary waves travel to fewer places on Earth's surface.

Secondary waves are faster than Primary waves.
Secondary waves are faster than Primary waves.

Secondary waves can travel through solids only.

Answer 1

Based on your statements about Primary (P) and Secondary (S) waves, here are the evaluations of each statement:

1. Primary waves can move through liquids, solids, and gasses. - True

   • P-waves are compressional waves that can travel through all states of matter: solids, liquids, and gases.

2. Primary waves travel to fewer places on Earth's surface. - False

   • P-waves can be detected at more locations on the Earth's surface compared to S-waves, as they can travel through both liquid and solid.

3. Secondary waves are faster than Primary waves. - False

   • S-waves travel slower than P-waves. P-waves are the fastest seismic waves.

4. Secondary waves can travel through solids only. - True

   • S-waves can only move through solids; they cannot travel through liquids or gases.

Summary of true statements:

• Primary waves can move through liquids, solids, and gasses.
• Secondary waves can travel through solids only.
