Question

1. Consider the map of rainfall in the Hubbard Brood watershed above. The large arrow indicates the general direction of water flow. Is the following statement true or false? Changes in pH as the water moves downstream suggests that the watershed neutralizes the rain water.

A. True

B. False

2. Consider the map above and the following statement: Rain falling at the edges of the Hubbard Brook Experimental Forest (edges of the map above) has neutral pH. Is the statement true?

A. True

B. False

Explanation / Answer

1. Consider the map of rainfall in the Hubbard Brood watershed above. The large arrow indicates the general direction of water flow. Is the following statement true or false? Changes in pH as the water moves downstream suggests that the watershed neutralizes the rain water.

A. True

B. False

This statement is true as ph value towards 7.0 indicate neutral whereas ph value less than 7.0 indicate acidity . therefore along the arrow changes in ph as the water moves downstream suggest that the watershed neutralizes the rain water .

2. Consider the map above and the following statement: Rain falling at the edges of the Hubbard Brook Experimental Forest (edges of the map above) has neutral pH. Is the statement true?

A. True

B. False

Yes this statement is true as the value of ph (edges of the map above ) almost 7 or near 7

Which indicate neutral ph
