Asked by the letter 7
A student has a birdbath made of poured concrete. When she bought it, the salesman suggested that she seal the surface with a watertight solution.
Why was this suggestion made?
A
The watertight solution would slow the evaporation of water during periods of warm weather.
B
Over time, rainwater would react with the surface of the concrete and deposit a mineral layer over the carved areas.
C
In cold, wet weather, any water that seeped into the concrete could freeze and cause the birdbath to crack.
D
When rainwater sits in a concrete basin, the pH becomes too acidic for the birds. The solution allows the pH to remain neutral.
