The map of an idealized tectonic plate and the earthquake hazards associated with each type of plate edge.

Answer to Problem 1QR
The map of an idealized tectonic plate contains three types of plate edges. The divergent motion causes small earthquakes, slide-past motion causes major earthquakes, and the convergent motion causes very large magnitudes of earthquake.
Explanation of Solution
Pictorial representation: Fig.1 represents a map of an idealized tectonic plate.

An earthquake is defined as a natural event which is caused by the sudden shaking of the surface of the earth. The occurrence of an earthquake is explained by the plate-tectonics theory, in which the lithosphere breaks into rigid plates that move away from, past, and into other rigid plates. This process is seen on the ground as individual faults, where the Earth ruptures and the two sides move past each other in earthquake-generating events.
The earthquake hazards that are associated with each type of plate edge are as follows:
(i) Divergent or pull-apart motion:
The divergent motion of tectonic plates occurs at the spreading centers. It causes the rocks to fail in tension, which results in the easy rupture of the rocks. It results in the yield of many small earthquakes.
(ii) Slide-past motion:
This motion occurs at the curved paths of Earth in the transform faults and causes the plates to slide and shear with each other. It results in causing major earthquakes.
(iii) Convergent or push together motion:
It occurs at the subduction zones and in continent-continent collisions, which causes the rocks to fail in compression. This motion stores immense amount of energy, which is released during very large magnitudes of earthquake.

Calculate the elevation of the water table at each well location and write the approximate elevation on the line next to each well. Next, use a colored pencil to draw smooth 10-foot contours that show the shape of the water table. (Start with the 1160-foot contour.) Use a pencil of a different color to draw arrows on the map to indicate the direction of the slope of the water table. a. Toward which direction (downward) does the water table slope? b. Referring to the site of the proposed water well, at approximately what depth below the surface should the proposed well intersect the water table? 2. Assume that a dye was put into well A on May 10, 2017, and detected in well B on May 25, 2018. What was the rate of groundwater movement between the two wells, in centimeters per day?
