Scientists use triangulation to find the epicenter of an earthquake. When seismic data is collected from at least three different locations, it can be used to determine the epicenter by where it intersects. Every earthquake is recorded on numerous seismographs located in different directions. Each seismograph records the times when the first (P waves) and second (S waves) seismic waves arrive. From that information, scientists can determine how fast the waves are traveling. Knowing this helps them calculate the distance from the epicenter to each seismograph.

To determine the direction each wave traveled, scientists draw circles around the seismograph locations. The radius of each circle equals the known distance to the epicenter. Where these three circles intersect is the epicenter.

Answer:

The given question is incomplete. It is missing an attachment which is added below. According to the attachment provided, the solution is as follows-

The seismologists commonly used the triangulation method from the data that is acquired by the seismograph. This method is used by the help of three seismographs that are placed at three different locations. During the time of the earthquake, these seismographs record the data and forms three distinct circles. These three circles obtained from the three seismographs intersect at a common point, and this point is the epicenter of the earthquake.

Thus, from the image, looking at the three circles and the intersecting point the epicenter can be determined.

Therefore, the three seismographs are used at Minneapolis, Detroit, and Charleston in order to find the earthquake epicenter.

The correct answers are:

1. Barrier island;

The barrier islands are island formed from the deposition of sediments, relatively close to the coastline. They are often in a linear shape, parallel to the shore, and being attractive tourist places.

2. Steep and rapidly exposed;

The cliffs are rocky structures that appear on the coastline itself. They are very steep, vertical, or even bent over the water bellow them, and they rise sharply above the water.

3. False;

The coastlines are changing constantly. The reason for that are the weathering and erosion processes, the deposition of sediments, as well as the rise or fall of the sea level.

A fossil mold that reflects the shape and surface markings of an organism is created when _____.
Lady bird [3.3K]

Correct answer: D). The organism is buried in sediment and then dissolved by underground water

Mold is a copy of an organism, it is formed like the first layer of sediments harden and forms a mold. Then after that new layer of sediment fills and become hardens.

The fossil is left behind in sediment, which removes the remains of an organism from its surrounding material. The groundwater along with its mineral content dissolves the organic matter to form the fossil.
