Which of the following are true about S waves 1. they begin at an earthquakes focus
2. they can travel through liquids
3. they can travel through solids
4. they move rock at right angles to the direction of wave travel

3. they can travel through solids

4. they move rock at right angles to the direction of wave travel

Explanation:

S waves are called transverse waves they have the ability to move past the solids. They cannot move through the liquids, these waves are perpendicular to the direction of travel.  They are also called longitudinal waves, the ad is second to record on the seismograph as they slowly pass through the rocks. They have a speed of 3.4 to 7.2 km as per the boundary.
