In a small town, a new factory has been built near a river that supplies water to the local community. After several months, the residents have noticed a change in the taste and smell of their tap water. There has also been an increase in cases of waterborne illnesses. What is the most likely way the factory is impacting the water quality in the town?
A) The factory is usually too much water, causing a shortage in the river.
B) The factory is discharging untreated chemical waste into the river.
C) The factory is blocking the river, preventing water flow.
D) The factory is usually water from the river for cooling purposes.
B) The factory is discharging untreated chemical waste into the river.

Which of the following best describes deposition?
A) The breaking down of rocks into smaller pieces
B) The movement of sediment from one place to another.
C) The chemical alteration of minerals in rocks.
D) The process of sediment settling and accumulating.
D) The process of sediment settling and accumulating.
During a heavy rainstorm, a small stream in a mountainous region becomes filled with water. The fast-moving water picks up various sizes of sediment, including sand, gravel, and small-moving river, the larger rocks settle to the bottom first, followed by the gravel, and finally the sand. Which of the following processes best describes how sediment is transported and deposited in the scenario above? 1. Sediment is carried within the water column and remains suspended as long as the water is moving. 2. Sediment particles bounce along the streambed, being lifted and dropped by the moving water. 3. Larger sediment particles roll or slide along the streambed due to the force of the moving water. 4. Sediment is dropped and settles out of the water as the flow of water decreases.
A) 1 only B) 2 and 3 C 3) and 4 D) 4 only
C 3) and 4
Which human activity is most likely to contribute to erosion?
A) Building dams
B) Planting crops
C) Constructing roads
D) Overgrazing by livestock
D) Overgrazing by livestock
Which landform is created by the deposition of sediment where a stream enters a large body of water?
A) Delta B) Valley C) Canyon D) Dune
A) Delta
Read the following statements about beach preservation: I. It is important to limit beach erosion because the dunes provide nesting habitats for birds and turtles. II. Beach erosion could weaken the ground under homes and businesses along the shoreline and cause the buildings to collapse. III.
