1. multiple choice which statement best describes groundwater?

a. water that only exists in rivers and lakes
b. water stored in spaces between soil and rock underground
c. water that forms only in clouds

1. written response using figure 1, explain the difference between the water table and an aquifer.

Explanation:

Analyze Question 1

The diagram shows groundwater stored in the saturated zone below the water table, filling the spaces (pores/crevices) in gravel and rock underground. This matches option B.

Analyze Question 2

The water table is the upper boundary of the saturated zone where all openings are filled with water. An aquifer is the entire underground layer of water-bearing permeable rock, gravel, or sand (the saturated zone itself) that stores and transmits groundwater.

• C. Water that forms only in clouds
• D. Water that can only be used after boiling

Question 2
