what would a person drilling a well most likely reach immediately after drilling through the unsaturated zone?\n○ a spring\n○ an aquifer\n○ the water table\n○ an impermeable layer
Answer
Brief Explanations:
To solve this, we recall the structure of underground water zones. The unsaturated zone is above the water table, where pores have air and some water. After drilling through the unsaturated zone, the next layer reached is the water table (the top of the saturated zone). A spring is a natural outflow, an aquifer is below the water table, and an impermeable layer is deeper. So the correct option is the water table.
Answer:
the water table (the option "the water table")
