To find the epicenter (the point on the earth's surface where an earthquake begins) during earthquakes, one need to view the seismogram (a record of the ground motion), and at least two other seismographs recorded for the same earthquake. Other instruments such as a map, a compass for sketching circles on the map, a ruler, and a pencil will also be used.
The following are the steps of the triangulation process in the correct order to find the epicenter during earthquakes:
Step 1: Subtract the time of P wave arrival from S wave arrival.
Step 2: See what the time difference is equal to in distance on a seismic wave chart.
Step 3: Draw circles representing the distances from at least three seismograph stations to the epicenter on a map.
Step 4: Find the point where all 3 circles intersect, and you've found the earthquake's epicenter.
Answer:
True
Explanation:
Subduction occurs when an oceanic plate runs into a continental plate and slides beneath it. (I hope this helps)
Answer:
C
Explanation:
A theory is like a guess. It may be supported by observations, but it is not proven by data. If it were, it would be a scientific law
Answer:

Explanation:
Part of studying the weather means looking at climate, or the weather patterns over a long period of time. Research done in Antarctica have given scientists a better idea of climate change, or how the climate and weather change over time.
