Question

Ava makes a diagram that compares a confined aquifer with an unconfined aquifer.

Which statements would make the diagram correct?

X: contains the water table
Y: found between impermeable rock
X: contains the water table
Y: has water under pressure
X: found between impermeable rock
Y: contains the water table
X: has upper surface of water at atmospheric pressure
Y: has water under pressure

Answer 1

X: found between impermeable rock

Y: contains the water table

Hope it helps

Answer 2

The correct option is this: X: FOUND BETWEEN IMPERMEABLE ROCK.
Y: CONTAINS THE WATER TABLE.
Confined aquifer refers to a water bearing layer, that is confined by a rock, which does not allow transmission of water. An unconfined aquifer is one that is not restricted by any overlain rock. Thus, confined aquifer is found between impermeable rock, while unconfined aquifer contain the water table.
