Marine exptoration of oil uses seismic waves to locate oil in the seabed. What is a negative impact from seismic waves on the aquatic ecosystem of the ocean?

A. Seismic waves kill microoganisms

B. Seismic waves disrupts the sand and causes seafloor erosion

C. Seismic waves have virtually no adverse affects on marine life

D. Seismic waves damage the sonar that dolphins and whales use to orient themselves underwater

The correct answer is - D. Seismic waves damage the sonar that dolphins and whales use to orient themselves underwater.

The seismic waves that are used for oil exploration have devastating effects on the marine life. On closer distance they are able to kill and seriously injure the animals that use sonar, like the dolphins and whales, but also the invertebrates, sea turtles, and lot of species of fish.

On longer distance, they might not cause sudden death, but will for sure cause injuries to lot of marine species, injuries that will lead to death soon after as they will not be able to function properly.
