Which of the following has not sped up the erosion of wetlands in coastal Louisiana? A. dredging of thousands of kilometers of canals throughout the wetlands
B. the increase in acidity of the rainwater in the southeastern United States
c. the loss of barrier islands the cost of Louisiana
D. the 2010 Deepwater Horizon well blowout

B. the increase in acidity of the rainwater in the southeastern United States

Explanation:

The dredging of thousands of canals throughout the wetlands for easier navigation has sped up the erosion of Louisiana wetlands so option A is false.

The loss of barrier islands on the coast of Louisiana as a result of rising sea levels has also sped up the erosion of the wetlands as they are now more exposed to open water so option C is wrong as well.

The 2010 Deepwater Horizon disaster spilled so much oil that adversely affected the wetlands leading to their erosion so option D is wrong as well.

Option B is therefore right.

igneous rocks which formed by the crystallization of magma at the surface of the earth called extrusive rocks. they are characterized by fine-grained textures because the rapid cooling at or near the surface did not provide enough time for large crystals to grow.
