What is the difference between unconfined aquifers and confined aquifers? Unconfined aquifers are saturated with water, but confined aquifers are not.
Confined aquifers are saturated with water, but unconfined aquifers are not.
Confined aquifers limit water flow in and out, but water flows freely in and out of unconfined aquifers.
Unconfined aquifers limit water flow in and out, but water flows freely in and out of confined aquifers.

This is important 1. what happens to the speed of molecules in water vapor when it condenses to form a liquid? (2 points) the molecules slow down. the molecules speed up. the molecules slow down and then speed up. the molecules speed up and then slow down. 2. how might human activities change to compensate for a decrease in water supplies? (2 points) humans might build a factory. humans might build drainage systems. humans might extract more water from the ground. human behavior does not change because of the water cycle. i'll be grateful if anyone can answer these 2 questions !
