Harper is doing a research paper about the drought in the Southwest United States. She learns that the Colorado River Basin has experienced over a decade of drought. Water storage for the region is at about half its capacity. Satellite imaging shows that over three-quarters of the water lost from the river basin came from groundwater. Which would be the best explanation about the drought for Harper to include in her paper?
  1. Water is a renewable resource that can always be replaced within a human lifetime.
  2. Water is a nonrenewable resource and can never be replaced within a human lifetime.
  3. Water in the river basin is being lost at a faster rate than can be naturally replaced through the water cycle.
  4. Water in the river basin is being replaced naturally through the water cycle at a faster rate than it is being lost.
