๐Ocean
The ocean covers about 71 percent of Earth's surface and holds roughly 97 percent of the planet's water, yet we have mapped more of the Moon than its seafloor. The five named basins, Pacific, Atlantic, Indian, Southern and Arctic, are technically one connected world ocean, and that single body of water regulates almost every climate signal on the planet. It absorbs around 90 percent of the excess heat trapped by greenhouse gases and stores massive amounts of carbon dioxide, which is partly why ocean acidification is one of the slow-moving crises of our century. Average ocean depth is about 12,100 feet or 3,700 meters, but the Mariana Trench plunges to nearly 36,000 feet, deep enough to swallow Mount Everest. On moomz, the ocean is a constant theme: people are obsessed with beaches, surfing, cruise drama, sea creatures, deep-sea horror, and whether they would rather drown or be eaten by a shark. The aesthetic alone makes ocean polls shareable. Whether you are a coastal kid with sand permanently in your shoes or an inland romantic who only sees the sea once a year, this page collects the moomz community's strongest ocean opinions. Vote your vibe and let the waves decide.
Why the ocean matters more than people think
The ocean is the planet's life support system. It produces over half of the oxygen we breathe, mostly through microscopic phytoplankton, and it stores around a thousand times more heat than the atmosphere. Currents like the Gulf Stream move warm water from the equator toward the poles, which is why Western Europe is much milder than its latitude alone would suggest. The ocean also feeds billions of people, supports millions of jobs through fishing and shipping, and is the backbone of global trade since roughly 80 percent of goods travel by sea. At the same time it is in trouble: warming, acidifying, losing coral reefs, drowning in plastic and being overfished in many regions. Despite all that, less than 25 percent of the seafloor has been mapped in detail, and scientists estimate that two out of three marine species are still undiscovered. The ocean is essentially the largest, most important habitat on Earth, and most of it is unknown territory.
Beaches, surf and ocean culture
For most people, the ocean is felt at the beach, on a boat or through a screen. The global beach tourism industry is worth hundreds of billions a year, and beach holidays dominate every must-visit list. Surf culture, born in Polynesia and exported by California and Australia, is now a global aesthetic that sells everything from clothing to skincare. Coastal cities like Barcelona, Rio, Sydney and Bali shape pop culture in ways landlocked places can only envy. The ocean also feeds horror: every shark attack story goes mega-viral, every cruise ship norovirus outbreak becomes a meme, and the deep sea, with its anglerfish and giant squid, remains one of the most reliably terrifying corners of the internet. On moomz, ocean polls slot perfectly between travel, fear and lifestyle themes. They are visual, emotional and instantly relatable, even if your only beach experience is a public pool in the suburbs.
Ocean polls that crush it on moomz
Strong ocean polls are usually either dream-vacation polls or terror polls. Best beach city on Earth, with options like Bali, Rio, Mykonos and Tulum. Ocean swim or pool swim. Cruise ship or backpacking the coast. Would you survive a week alone on a deserted island. Shark or jellyfish, which scares you more. Polls about identity also work: are you a sandy-feet beach person or a careful-towel beach person, do you actually swim or just float. The aesthetic component matters: a blue palette, a wave emoji and a clear question outperform walls of text. On moomz, ocean polls peak in late spring and summer but maintain a strong baseline year-round because of travel daydreams. Create one when you are planning a trip and watch your friends sell themselves as the perfect travel buddy in the comments.

Frequently asked
Q.How deep is the ocean on average?+
The average depth of the ocean is about 12,100 feet, or roughly 3,700 meters. That number hides a huge variation. Continental shelves are shallow, often less than 200 meters, while the abyssal plains stretch out at around 4,000 meters. The deepest known point is Challenger Deep in the Mariana Trench, at about 36,000 feet or 10,935 meters below sea level. If you placed Mount Everest at the bottom of that trench, its summit would still be more than a mile underwater. That is one of moomz's favorite trivia drops.
Q.How many oceans are there?+
Traditionally, scientists name five oceans: the Pacific, Atlantic, Indian, Southern and Arctic. They are really one connected body of saltwater called the world ocean, but the divisions are useful for navigation, climatology and political purposes. The Southern Ocean, ringing Antarctica, was the most recent to gain widespread official recognition, around 2021. The Pacific is by far the largest, holding more than half of all ocean water, and the Arctic is the smallest and shallowest. Each basin has its own unique currents, ecosystems and weather patterns.
Q.Why is the ocean salty?+
The ocean is salty because rivers and rain slowly dissolve minerals from rocks on land and carry them to the sea. Over hundreds of millions of years, those minerals, especially sodium and chloride, have built up in seawater that constantly evaporates but only releases the water itself back as freshwater. Underwater hydrothermal vents add even more dissolved minerals. The average salinity is around 35 grams of salt per kilogram of water, but it varies: the Mediterranean and Red Sea are saltier, while the Baltic is much less so.
Q.Is the ocean really in danger?+
Yes, in several ways. Warmer waters bleach coral reefs, which support a huge share of marine biodiversity. Higher CO2 levels acidify the ocean, weakening shells and skeletons of many species. Overfishing has collapsed key fisheries, and plastic pollution, including microplastics, has reached the deepest trenches. None of this is hopeless: marine protected areas, sustainable fishing rules and plastic bans are already showing local wins. On moomz, environmental polls often trend, which is partly why people feel they should care, and partly because nothing rallies opinion like saving turtles.
