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.

Assimilation was practiced by the Europeans against the Native Americans.
Explanation:
Cultural Assimilation is referred to as the process where small groups or culture form a dominant group. The cultural assimilation was an effort made by the Europeans to convert the culture of Native Americans into the culture of European- American in between 1790 and 1920.
United States also established boarding school for the Native American and the children had to attend the school. In case of cultural assimilation a person's language or a group of person's language and culture tries resemble with another group.
