The correct labels for the layers within the Earth regarding groundwater are typically as follows:
-
Zone of Aeration (A): This is the upper layer where the soil and rock are not saturated with water. The spaces between the soil particles contain both air and water.
-
Water Table (B): This is the boundary between the zone of aeration and the zone of saturation. It represents the top of the saturated zone.
-
Zone of Saturation (C): This layer is below the water table and is fully saturated with water. All the spaces between soil and rock particles are filled with water.
Based on this understanding, the correct response would be:
A. zone of aeration - B. zone of saturation - C. water table.
However, if the order is meant to follow the general description of layers from top to bottom (zone of aeration, water table, and zone of saturation), the correct option would be:
C. A. zone of aeration - B. water table - C. zone of saturation.
So, the final answer is C. A. zone of aeration - B. water table - C. zone of saturation.
