One of the interesting facts about the ocean is that it generally consists of a great composition of saltwater and it separates continents.Oceans are massive bodies of water that connect smaller oceans. Since the oceans are connected, they appear to be one ‘ocean’ when seen as a whole.Our planet’s oceans encompass 72% of its surface. The Pacific Ocean, being the largest among all oceans, takes up about 30% of the planet’s surface. The sunshine oceanic zone gets sunlight, which can affect water temperature and allow organisms to do photosynthesis. It makes up one-third of the Earth’s surface. The oceanic environment is home to a variety of large and little fish. Oceans are home to crabs, starfish, sharks, and whales, among other creatures. Have you ever been to the sea and noticed that the water is suddenly far down the beach and then creeping up higher? It is known as tides, and it is created by the Earth spinning while the moon and sun’s gravitational pull has an impact on the sea. Our oceans today may have been not as they used to be. They are filled with plastic, pollution, oil, and many other harmful substances. However, the ocean holds great importance for the survival of all living beings since it is responsible for offering us more than half of the oxygen in the world and many creatures live in it too. But, we have come to the point where our oceans and even land are not safe from climate change due to its drastic effects on the sea or aquatic life of marine animals like fish, plants, and its ecosystem as a whole.For more content similar to ocean facts, you can also visit jungle vs rainforest facts and facts about the oldest bonsai tree.What are oceans and how they were made?Some interesting ocean facts for kids are that the ocean enfolds beyond 70% of the Earth’s exterior or surface, more than 90% of wildlife on earth exists in these oceans, and the lengthiest chain of mountains is found under the ocean. The Atlantic Ocean, Indian Ocean, Pacific Ocean, and Arctic Oceans are the four named oceans, out of which the Pacific is the largest among all. Most countries, including the United States, now consider the Southern (Antarctic) Ocean to be the fifth ocean. The Atlantic Ocean, the Indian Ocean, and the Pacific Ocean are the famous, known world’s oceans. If you could go back in time to around 4.5 billion years ago and visit the Earth’s surface when it was first developing, it would be nothing like it is now. For starters, it would be filled with more sunlight and warm energy that the rocks would be molten, which means they would be liquid. Earth gradually cooled over millions of years, and the hard outer crust of the Earth developed.Have you ever held a cool bottle of water in your hands in the sunlight? The bottle begins to dry but quickly becomes moist. The concern is how the water gets here, and this is because air contains water vapor. When the warmed-up air is exposed to a cold bottle, it cools, and the water vapor condenses into a liquid called water. Condensation generally takes place when the oceanic vapor of water (a gas) converts to wet moisture - water. Scientists believe that when the Earth’s molten rocks cool, they discharged steam (water vapor) into the atmosphere. This water vapor cooled, condensed, and showered back down onto the Earth’s surface. Scientists think that this is one of the ways the seas evolved. Is that how all the water came to be? Most likely not. Comets generally consist of large dust and ice chunks that remained after stars and planets formed. Asteroids are massive ice-like rocks that are minor planets left behind from the formation of planets and stars. A meteor is an asteroid that penetrates the Earth’s surface. Meteors usually burn up as they travel through the Earth’s atmosphere, although some bits do remain. These fragments are known as meteorites. Some scientists believe that comets, asteroids, and meteorites contributed to the formation of water in the ocean.How many oceans are there on planet Earth?Many countries and oceanographers may say there are four famous world’s oceans, based only on the Atlantic Ocean, Pacific Ocean, Indian Ocean, and Arctic Ocean. According to America, five oceans exist, namely, the Indian Ocean, Pacific Ocean, Atlantic Ocean, Arctic Ocean, and the Southern, formerly called the Antarctic. Among them, the Mariana trench is the most in-depth or deepest point. Each ocean has a distinct ecology that governs the marine animals that may dwell there. Let’s dive deep into each ocean.Arctic OceanThe Arctic Ocean which is the smallest of the five oceans encompasses approximately six million sq. mi (around 14 million sq. km) and has a shoreline of about 30,000 mi (48280.32 km). This ocean is the most in-depth among the five oceans, due to its maximum depth being around 18,456 ft (5625.38 m). The Arctic also poses to be the coldest among the oceans, with frosty temperatures all year, and much of its water enclosed in ice. During the winter, the region receives lengthy periods of darkness. Summer months, on the other hand, have longer durations of sunlight. The Arctic Ocean floor contains petroleum and natural gas deposits. Extreme warming trends in the Arctic have resulted from climate change.Atlantic OceanOn average, the Atlantic Ocean has a depth of about 3646 mi (5867.67 km) and is known to be the second-biggest or largest ocean among the rest. The Milwaukee deeper in Puerto Rico has the deepest water. The trench is nearly 3.1 mi (5 km) long. To the north, the Arctic Ocean encircles the Atlantic. To the south is the Southern Ocean. The Indian Ocean lies southeast of the Atlantic Ocean, whereas the Pacific Ocean lies southwest of it. Because of its vast extent, the climates on its northern and southern edges differ. Different temperatures of the Atlantic have also been discovered to affect land temperatures in the surrounding areas.Pacific OceanThe Pacific Ocean encompasses more than 60 million sq. mi (more than 165 million sq. km), accounting for 33% of the Earth’s total surface (land) area. It is among the largest ocean, with great depth too. The Pacific Ocean primarily means ‘calm sea.’ The Mariana Trench, located in the western part of the Pacific Ocean to the east region of the Islands of Mariana, is the most in-depth known section of Earth’s seas. This ocean has roughly 25000 distinct islands, which is far more than the other seas on Earth. The Challenger Deep, located in the legendary Mariana Trench in the western region of the North Pacific, is a portion of the ocean that has been studied in-depth. The ocean stretches starting with California in America to the region of China, with South America and Australia along its western shore. The Pacific Ocean has warm water than the Atlantic Ocean. The temperature ranges from 32-84 ℉ (0-28.88 ℃)Indian OceanWith a surface area of nearly 28 million sq. mi (70.5 million sq. km), the Indian Ocean is the third largest ocean on the planet. The high concentrations of salt create an upward thrust, enabling you to float effortlessly in the water, which is 5 mi (8.04 km) deep and has an average depth of more than 2 mi (3.21 km). The ocean lies to Europe’s and Asia’s south. Africa is located to the west and Australia is located to the east. The Indian Ocean’s waters are usually warm, providing an ideal setting for a diverse range of phytoplankton and plants life. Tuna and shrimp are common fishing points or targets due to the good fishing environment. The Great Barrier Reef, located off the coast of Australia, is the biggest coral reef in the world. Coral reefs can only thrive in tropic waters, but climate change has resulted in the loss of more than half of the world’s reefs in the last 30 years.Antarctic OceanThe Southern Ocean, which was before known as the Antarctic Ocean, is the ocean lying afar south among all oceans. The Southern Ocean, the fourth biggest ocean, surrounds Antarctica and includes the southernmost sections of the Pacific Ocean, Atlantic, and the Indian Ocean. The Southern Ocean covers around 7.8 million sq. mi (20.3 million sq. km) and has an average depth of 13,000-16,000 ft (3962.4-4876.8 m). The icebergs in the Southern Ocean are made of freshwater. The Drake Passage, which is 600 m (965.61 km) wide, is the most narrow region. This stretch of sea connects the Antarctic Peninsula to the South American continent. The water temperature ranges from 28-50 ℉ (-2.22- 10 ℃).How many animals live in the ocean?It is hard to know the actual number of species that dwell in the ocean due to its immense vastness. Let’s take deep dive into many amazing ocean facts for kids and check how many species in the ocean are declining. The continuous decrease in the health of many ecosystems, along with growing extinction rates, are likely surpassing species’ capacity to develop to cope with our fast-changing planet’s environment. But it’s not all terrible news.Researchers from all across the globe are continuing to investigate marine life and environments to create new techniques for preserving crucial ocean ecosystems. According to scientists, 91% of ocean species have yet to be categorized, and more than 80% of our ocean remains unmapped, unseen, and undiscovered. While these figures may appear overwhelming, they have not deterred the worldwide scientific community from attempting to accumulate as much knowledge about marine life as possible. As per scientists, it has been estimated that more than one million animal species live in the ocean.Which is the biggest animal found in the ocean?With a wingspan of up to 29 ft (8.84 m), the huge manta ray is the world’s biggest ray. Their nutrition comprises the smallest of creatures zooplankton for such a huge animal. Giant manta rays are filter feeders that are beautiful and compassionate. Giant manta whales are not just massive, but also extremely intelligent, with the greatest brain among other fish.Sperm whales have the largest skulls and brains of any animal on the planet, as well as the loudest voice. A sperm whale can also hold its breath for up to two hours at a time when looking for prey at depths of up to 1.86 mi (3 km) in the sea. Fun fact - Moby Dick’s white whale was inspired by two real-life sperm whales.Whale sharks are the world’s largest fish, growing up to 40 ft (12.19 m) long and weighing up to 20,000 lb (9071.85 kg). That is the combined height and weight of two elephants stacked on top of each other. The whale shark is a big, gentle behemoth.The blue whale is ranked first! Blue whales are not only the largest animals that live today, but they are also the largest mammals that have ever existed. A blue whale may reach 100 ft (30.48 m) in length and weigh up to 200 tons (181437 kg). The mouth of blue whales may weigh as much as an elephant, and its heart as much as a car. What can such big sea animals eat? Krill are little shrimp-like animals that they feed on.Here at Kidadl, we have carefully created lots of interesting family-friendly facts for everyone to enjoy!
