Answer:
B. P waves can travel through liquids
Explanation:
P waves or primary waves are elastic waves produced from an earthquake. They are the first waves that arrives a Seismic station when an earthquake disturbs the earth.
P and S waves are both body waves that moves within the earth.
P- waves travel faster than S- waves and can propagate through any medium. S-waves or Secondary waves are shear waves that can only propagate through soilds.
Both waves are longitudinal and moves parallel to their source of propagation. They move by disturbing other particles in their line.
Transverse waves are the love and rayleigh waves. They are both surface waves that travels and cause disturbance on the surface of the earth during an earthquake. They move up and down.
Cold fronts appear in areas of large temperature and air pressure decrease, whereas warm fronts appear in areas of Temperature and air pressure increase.
<h3>What are cold fronts?</h3>
Cold fronts are masses of atmospheric air that exert pressure on light warmer air masses, which then tend to rise in the atmosphere.
Cold fronts can be diagrammed in weather maps as blue lines and different triangular forms with sense to the region where they move.
In conclusion, cold fronts appear in areas of large temperature and air pressure decrease, whereas warm fronts appear in areas of Temperature and air pressure increase.
