What percentage increase in population did Hidalgo and Willacy counties experience from 1997 to 2007? What problems can a rapidly growing population pose to a watershed?

The answer is below

Explanation:

1. A) The percentage increase in population in Hildago between 1997 to 2007 is:

Given that Hildago population in 1997 = 511, 324

Hildago population in 2007 = 726,604

Hence, the percentage increase is 726,604 - 511,324 = 215280

Then 215280 ÷ 726604 = 0.2962 ≈ 29.62%

1. B) For Willacy

Willacy population in 1997 = 19,332

Hildago population in 2007 = 20,600

Hence, the percentage increase is 20,600 - 19,332 = 1268

Then 1268 ÷ 20600 = 0.0615 ≈ 6.15%

2.  The problem a rapidly growing population posed to a watershed are:

A.  impaired water bodies

B.  percentage of surface waters impaired increases

C.  source of pollution

D.  number of waste water facilities draining into the water bodies.

b. read the phase at the intersection of any given temperature and pressure.
