Where is water on Earth (link #2)?
Importance of Groundwater (link #2) (GW = water located below Earth's surface)
Responses needed from Students.
Water Overview (link #2) - most essential compound for life, plants + infants =

properties, compared to other molecules of similar molecular weight, e.g., NH , HF, +
H S. Why?
Physical Properties of Water (link #2) High melting point + high boiling point
We use <1% of Earth's water; much more GW available than lakes + rivers.
