Student Answer Evaluation Exercise
In response to the question “Is there groundwater below lakes?” a student wrote the following response. The instructor gave the answer a score of 7 out of 10 and wrote the following comment on the assignment: “You have clearly understood some of the concepts related to this topic, but you have not yet pulled all the key ideas together. Think a little more about the difference between surface water and groundwater systems.”
Review the student’s answer, and write a more complete response.
Is there groundwater below lakes?
No, there should not be any groundwater below lakes. Groundwater is present in rocks with good porosity and permeability. If rocks under a lake had good porosity and permeability, then the water from the lake would drain out into the groundwater and the lake would be gone. But if the rock under the lake had bad permeability and porosity, then water could not move into it and the lake would not lose water.
