Question

which statement about the water table is accurate? a) it sits above the zone of aeration. b) it isnt affected by precipitation. c) it fluctuates with the seasons. d) its deeper underground, under valleys. question 15 (5 points) which of the following is an example of point - source pollution? a) water from a sewage treatment plant b) acid from abandoned mines c) fertilizer from agricultural runoff

Explanation:

1. For the water - table question:

• The water table is the upper surface of the zone of saturation and is below the zone of aeration. It is affected by precipitation as more rainfall can raise the water table. It is generally shallower under valleys due to surface - water accumulation. It does fluctuate with the seasons as precipitation and evaporation patterns change.

1. For the point - source pollution question:

• Point - source pollution comes from a distinct and identifiable source. Water from a sewage treatment plant is a point - source as it has a specific outlet. Acid from abandoned mines and fertilizer from agricultural runoff are non - point sources as they spread over a large area and are not from a single, easily identifiable point.

Answer:

1. C. It fluctuates with the seasons.
2. A. Water from a sewage treatment plant
