The map shows theoutlines and ages of several calderas created as a result of volcanic activity over the last 16 millionyears as the North American Plate moved over the Yellowstone Hot Spot. A and B represent locationswithin the calderas.

The Yellowstone Hot Spot

The Yellowstone Hot Spot has interacted with the North American Plate, causing widespreadoutpourings of basalt that buried about 200,000 square miles under layers of lava flows that are ahalf mile or more thick. Some of the basaltic magma produced by the hot spot accumulates nearthe base of the plate, where it melts the crust above. The melted crust, in turn, rises closer to thesurface to form large reservoirs of potentially explosive rhyolite magma. Catastrophic eruptionshave partly emptied some of these reservoirs, causing their roofs to collapse. The resulting craters,some of which are more than 30 miles across, are known as volcanic calderas.

Calculate, in miles per million years, the rate at which the North American Plate has moved over theYellowstone Hot Spot between point A and point B.

The map shows ocean depths, measured in meters, off the coast of Massachusetts.Points A, B, and C represent locations on the ocean floor. The Stellwagen Bank discussed in thepassage is lightly shaded and labeled on the map.

The Stellwagen Bank

One of the most exciting adventures for a visitor to Cape Cod, Massachusetts, is going on awhale watch. Large boats leave port two to three times each day carrying passengers to a specificlocation in the Atlantic Ocean to see the whales. How do the captains of the boats know where tofind the whales? The answer is simple. They look for the whales over an area known as the Stellwagen Bank,which is a large undersea deposit of unsorted sand and gravel. The Stellwagen Bank is inferred byscientists to have formed during the Pleistocene Epoch from the slow retreat of massive Ice Ageglaciers across this area. Today, cool ocean currents come from the north and flow up and over theStellwagen Bank. These currents bring nutrients to the surface from deep in the ocean, providingfood for oceanic phytoplankton (small plants). Small ocean creatures and fish feed on thephytoplankton. Whales can be found in abundance at the Stellwagen Bank feeding on the manyocean life-forms.


63. Identify the most probable cold ocean current causing the upwelling of nutrients over the StellwagenBank.

64. Most whale watching takes place at 42° 25' N and 70° 25' W. On the map, place an X at this location.
