21 Quiz 1. T or F, a watershed is the source of a streams water. 2. T or F, subsidence occurs when ground water is removed. 3. T or F, a terminal moraine occurs along the sides of a flowing glacier. 4. T or F, plankton are organisms that can actively swim against a current. 5. T or F, the salt in the oceans comes from the weathering of rocks on land.
