Harnessing the energy of tides to generate electricity is different than the force moving the water in a hydroelectric power station at a dam because
A) tidal energy uses turbines and a dam uses generators.
B) tidal energy ultimately relies on moon's gravity and hydroelectric power ultimately relies on the energy from the sun.
C) tidal energy ultimately relies on ocean currents and hydroelectric power ultimately relies on the energy from the sun.
D) tidal energy ultimately relies on the wind and hydroelectric power ultimately relies on the energy of rain.

Name two other oxbow lakes shown on the map (either natural or artificially produced).
The following questions are based on Map T-5, a portion of the “Jackson, Mississippi-Louisiana” topographic map (scale 1:250,000; contour interval 50 feet; dashed lines are supplementary contours at 25-foot intervals). This map shows the Mississippi River near the town of Vicksburg, Mississippi (32°49'56"N, 91°11'07"W). A color satellite image of this same region is shown in Figure 40-5 (scan the QR code for this exercise or go to the Lab Manual website and Exercise 40). The eastern bluffs of the Mississippi River floodplain can be seen in the southeast corner of the map. The dashed black line along the Mississippi River shows the state boundary between Mississippi and Louisiana. Notice that the “boundary course” of the Mississippi River is quite different from the present course of the river. Some of the changes were natural, others were artificial. There is an extensive set of artificial levees along the course of the river (shown with closely spaced brown tick marks). What will be an ideal response?
