question 17 (5 points)

whats a recharge area?
a) the part of an aquifer thats located between two aquicludes
b) the part of an aquifer thats located at a lower elevation
c) the part of an aquifer where groundwater meets a lake or stream
d) the part of an aquifer where surface water reaches the water table

Explanation:

For Question 16, when a rock drops vertically from a cliff, it is falling due to gravity. "Slide" implies movement along a surface, "flow" is more for substances like liquids or loose - materials in a continuous mass, and "slope" is a surface with an incline, not the motion.
For Question 17, a recharge area of an aquifer is the area where surface water infiltrates and reaches the water table, replenishing the groundwater. An aquifer between two aquicludes is a confined aquifer, location at lower elevation doesn't define a recharge area, and the meeting of groundwater with a lake or stream is not the definition of a recharge area.

Answer:

Question 16: B. Fall
Question 17: D. The part of an aquifer where surface water reaches the water table
