a.
To determine:
Whether the deep-focus earthquakes occur along the Pacific basin or Atlantic basin.
Introduction:
Earthquakes are caused by rupture of the geological plates. It is shaking of the surface of Earth. It is due to the movement of tectonic plates.
b.
To determine:
Whether the earthquakes that occur along the western margin of South America are deeper or shallow.
Introduction:
The western margin of South America has a convergent plate. It has a boundary between the South American Plate and the Pacific Plate.
c.
To determine:
Whether the earthquakes around the Western margin of North America are deep or shallow.
Introduction:
The Western part of North America is covered by Pacific Basins. Earthquakes are caused by rupture of the geological plates. It is shaking of the surface of Earth. It is due to the movement of tectonic plates.

- I need help with tracing part A could I get some helparrow_forwardActivity 12.3: Wave Refraction Pgs 202-203Figure 12.2 is a map view of a headland along a coastline. The water depths are shown by blue contour lines. As you complete the following questions, assume that waves with a wavelength of 60 feet are approaching the shoreline from the bottom left of the figure. 1. At approximately what water depth-10, 20, 30, or 40 feet-will the approaching waves begin to touch bottom and slow down? (Hint: Recall that this occurs when the water depth is one-half the wavelength.) Approximately the 30-foot depth line. 2. Using the wave shown in Figure 12.2 as a starting point, sketch a series of lines to illustrate the wave refraction that will occur as the wave approaches the shore by following these steps:Step 1: Mark the position on the 30-foot contour line where the wave front will first touch bottom.Step 2: Knowing that the section of the wave that touches bottom will slow down first, sketch the shape of the wave front when it reaches the 20-foot contour…arrow_forwardN Depth of water contour Advancing wave crest Beach HEADLAND -10'- 20'- -30- Land -40- -50'- 0 Beach Scale 200 feetarrow_forward
