Ayo, my fellows who searched here for the ANSWERS:

Tracking Earthquakes Quick Check:

1: Magnitude measures the energy released by the earthquake, while intensity measures the amount of damage.

2:There is more likely to be an earthquake in Region A than in Region B.

3: P waves push and pull in the same direction as the wave, and S waves move up and down.

4: the vibrations produced by an earthquake

Hope this helps :)
