How did the Everglades wetlands become drier?
Question 14 options:

Dam and canal building diverted the historical flow of water away from the Everglades.

Dam and canal building forced water into underground aquifers to expose wetlands.

More water was used to irrigate out-of-state farms than could be replenished by rainfall.

Answer 1

(1) A soil horizon is a layer of soil that is generally parallel to the crust, the physical properties of which differ above and below. Thus, the answer to this first question is the third choice.

(2) The drying out of the once very wet lands of the Everglades is brought about by the change in climate. Thus, the answer is the fourth choice.
