I really need this now please help (also 30 points for answer, and brainliest) Describe (name and give details about) three dangers of voyages of exploration.

I had to do something like this too and with this answer, i got extra credit on top of 100% bc of the detail. Hope this helps. Happy Holidays!

Explanation:

1. Exploration is inherently dangerous. The DEEPSEA CHALLENGE team is cognizant of the risk of traveling to the ocean’s deepest point and does everything possible to mitigate the many hazards. Under the leadership of James Cameron and Ron Allum, each and every member of the team is encouraged, even required, to be explicit about the risks that are simply part of their work. The expedition philosophy follows the thinking that the only way to protect against risk is by anticipating, understanding, and addressing it outright. There is a great deal to be gained if DEEPSEA CHALLENGE is successful, but all members of the expedition acknowledge that lives are at stake and that, as Cameron himself has written, “there are a lot of ways to die.”

2. HYDROTHERMAL VENT-INDUCED MELTDOWN

As first reported in expedition blogger Dr. Joe MacInnis’s March 18 entry, several of the expedition’s members, including the legendary Captain Don Walsh, one of two people ever to have been to the Challenger Deep prior to this expedition, discussed the risks of “flying a research sub too close to a hydrothermal vent,” where they “casually mention[ed]” that the water temperature approached 700 degrees and would melt a sub’s viewport.

3. SEAFLOOR COMMUNICATIONS CABLE ENTANGLEMENT

Submarine communications cables are cables that traverse the seafloor between land-based stations to extend telecommunication signals across stretches of ocean. Were the sub to become entangled in these cables, it might prevent it from returning to the surface.

2018 means 2018 ce or common era

there have been other eras too including bce, which included way more years.

no one really purchased it themselves, it was all america, they had debates etc.
