Question

water that travel throughout the oceans. currer ecosystems. for example, they carry plankton deepwater creatures, which is vital for the ecosystem. ocean currents also affect water temperatures, climate, tides, and weather events. understanding the shape of the seafloor and any changes to it can provide invaluable early warnings to ships and coastal cities about sea - level increases, tsunamis, and storms. according to the united nations, 40 percent of the worlds population lives within 60 miles of a coast. humanity can benefit from understanding what is going on under the oceans surface.
6 finally, beyond the known benefits, a rich treasure trove of unknown discoveries is waiting on the seafloor. already, studying this unique environment has revolutionized science in important ways. for example, the discovery of ecosystems in thermal vents deep underwater changed how we view life requirements. coastal mapping coordinator ashley chappell at the u.s. national oceanic and atmospheric administration explains, \data is used in coastal ocean science, habitat characterization, wave models, flooding models, wind energy development, all kinds of things.\
7 humankind already extracts resources such as fish and oil from the ocean. in fact, three billion people eat fish as a main source of food. understanding what else is going on under the sea will help us protect that food

williams, kyono - ruck
which quotation from the article best shows that ocean floor mapping can help save peoples lives?
a this goal requires collecting data from scientists, businesses, and even regular citizens, along with the use of new seafaring remote - control vessels that map ocean floors. (paragraph 3)
b knowing the safest places to lay these cables helps ensure countries stay connected, boosting all economies. (paragraph 4)
c understanding the shape of the seafloor and any changes to it can provide invaluable early warnings to ships and coastal cities about sea - level increases, tsunamis, and storms. (paragraph 5)
d for example, the discovery of ecosystems in thermal vents deep underwater changed how we view life requirements. (paragraph 6)

Explanation:

The question asks for a quotation showing ocean floor mapping helps save lives. Option C links seafloor understanding to early warnings about sea-level increases, tsunamis, and storms—events that directly threaten human lives. Other options focus on data collection (A), economic connectivity (B), or scientific discovery (D), not life-saving impacts.

Answer:

C. Understanding the shape of the seafloor and any changes to it can provide invaluable early warnings to ships and coastal cities about sea-level increases, tsunamis, and storms. (paragraph 5)
