Distinguish between primary and secondary waves seismic waves
Answers
Answer:Primary waves travel faster, move in a push-pull pattern, travel through solids, liquids and gases, and cause less damage due to their smaller size. Secondary waves travel slower, move in an up-and-down pattern, travel only through solids, and cause more damage due to their greater size.
Explanation:
Answer:
Primary seismic waves
1. The seismic waves that reach the earth first, immediately after the energy is released in the interior are called primary seismic waves.
2. Primary seismic waves can travel through all the three mediums i.e. liquid, solid and gaseous.
3. The particles lying in the way of primary seismic waves move to and fro in the direction of energy transfer.
4. Compared to secondary seismic waves, the primary seismic waves are less destructive.
B) Secondary seismic waves
1. The seismic waves that reach the earth after the primary seismic waves are called secondary seismic waves.
2. Secondary seismic waves can travel only through the solid medium.
3. The particles lying in the way of secondary seismic waves move up and down in the direction of energy transfer.
4. Compared to primary seismic waves, the secondary seis mic waves are more destructive.
