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:
Chemical weathering is different from mechanical weathering because the rock changes, not just in size of pieces, but in composition. ... Chemical weathering works through chemical reactions that cause changes in the minerals.
Near an ocean-continental convergent boundary
Answer:
I'm pretty sure it's c
Explanation:
It's the only one that makes sense because there were sets, there were costumes, and I don't think there were too many camera angles because that doesn't make sense either.
Contour lines on a map display the differences in elevation. Hope this helps
