1 How many oceans are there on Earth? Icon 4 oceans Icon 5 oceans Icon 6 oceans Explain Earth has 5 different oceans including: Pacific Ocean, Atlantic Ocean, Indian Ocean, Arctic Ocean, Southern Ocean. The world’s oceans cover about 71% of the Earth’s surface area. 2 The area of ​​the Pacific Ocean is about…? Icon Approximately 155.25 million square kilometers Icon Approximately 165.25 million square kilometers Icon Approximately 175.25 million square kilometers Explain According to Kinky Data, the Pacific Ocean covers an area of ​​about 165.25 million square kilometers, accounting for one-third of the total surface area of ​​the globe. All of the land on Earth combined (about 150 million km2) still cannot cover the surface of this ocean. 3 The Pacific Ocean separates Asia from which of the following continents? Icon Oceania Icon Americas Icon Both answers above Explain The Pacific Ocean stretches from the Arctic Ocean in the north to Antarctica in the south. The width of the east-west is up to 19,800 km, the widest part, separating Asia, Oceania from the Americas. What is the deepest point in the Pacific Ocean? Icon Nearly 9,000 m Icon Nearly 10,000 m Icon Nearly 11,000 m Explain In addition to the largest area, the Pacific Ocean is also the deepest ocean on Earth. Kinky Data information, the Pacific Ocean has an average depth of 4,280 m. The deepest point of the ocean is the Challenger abyss located in the Mariana Trench, nearly 11,000 m deep. This is also the deepest point of the Earth’s crust, 13 times the height of the Burj Khalifa tower – the world’s tallest building in Dubai. If Everest could be placed at the bottom of the Mariana Trench, the world’s tallest mountain would still be nestled beneath the Pacific Ocean. According to INSH, the Mariana Trench was formed about 180 million years ago, but the Challenger abyss was only discovered in 1875. This abyss is one of the hardest places on Earth to explore. The pressure there is 1,000 times greater than the pressure on land. Only three people have ever ventured down to explore by submersible. The sea temperature in Challenger is as low as freezing point (only 1.1 to 3.9 degrees Celsius). Meanwhile, water from vents at the bottom of the abyss can be as hot as 450 degrees Celsius, but cannot boil due to too much pressure. In return, it is rich in minerals, which help sustain many marine creatures in harsh conditions. 5 The name Pacific (Pacific) was given by the explorer from which country? Icon Portugal Icon Netherlands Icon Spain Explain According to the National Ocean Service, in 1519, a Spanish expedition, led by the Portuguese navigator Ferdinand Magellan, set out on a transatlantic voyage to find a route west to the Spice Islands via the Spice Islands. South America. After bravely crossing dangerous seas, including the area now known as the Strait of Magellan, the expedition entered an unknown ocean in November 1520. He called it “pacific”, means peaceful sea, due to the calmness of the water at that time. When Magellan and his expedition reached the Pacific Ocean after a long journey, they thought the Spice Islands were near. They never imagined that the destination was still thousands of miles away and that they were in the largest ocean on Earth. On which side of the equator are most islands in the Pacific Ocean? Icon North Icon Southern Icon West Explain The Pacific Ocean has between 20,000 and 30,000 islands, and most of them are south of the equator. What are the basic types of islands in the Pacific Ocean? Icon 3 types Icon 4 types Icon 5 types Explain Islands in the Pacific Ocean fall into four basic categories: continental islands, volcanic islands, reefs, and raised reefs. The world’s largest floating trash island in the Pacific whirlpool is now 3 times larger than which water? Icon Italy Icon Belgium Icon France Explain The floating garbage island in the Pacific Ocean is an area of ​​​​1.6 million square kilometers located between Hawaii and California, USA. The area of ​​garbage island as of 2018 is nearly three times larger than that of France (643,801 km2). Weighing up to 80,000 tons, the island is a revolving mass of beach debris, consisting of plastic bags, undigested plastic bottles and other trash. Confined to the currents of the North Pacific vortex, a giant eddy and a meeting point for ocean currents, the island of trash rotates between Hawaii and the Pacific Ocean. mainland North America. Four other whirlpools in the world’s oceans also contain millions of tons of polluting debris. Debris floats on the water, but in some places up to meters deep, can have ominous consequences for the environment. Marine mammals, turtles and seabirds may mistake decomposing plastic waste for plankton – their primary source of nutrition – and eat it, damaging the digestive system. How are storms in the Pacific Ocean named? Icon By number of the year Icon Take alternately from the list of countries in the proposed area Icon Both answers above Explain The storm’s name in the Pacific is taken from a database compiled by the World Meteorological Organization’s (WMO) Tropical Cyclone program, according to AccuWeather. “Weather forecasters have a list of special names for hurricanes. Periodically, one name is no longer used and replaced by a new name,” said Jim Andrews, senior meteorologist at the National Weather Service. weather forecaster AccuWeather said. This list includes 140 names selected by countries in the region such as China, Japan, Vietnam and Cambodia. There is no restriction on the number of appellations that may be used in a calendar year. The names in the list are only given to tropical cyclones of hurricane level and above and are taken in order from top to bottom. If the list of names for that year is exhausted, the storm names will be taken from an additional list of 10 names and will be released before the hurricane season begins. A tropical cyclone in the northwest Pacific is classified as a hurricane if it has winds between 73-148 km/h. If the storm has winds of 149 km/h or more, it will be classified as a super typhoon.

1. Where is the latest named ocean? Icon Atlantic Icon Indian Ocean Icon southern Ocean The correct answer is answer C: The Southern Ocean is the newest ocean to be named. Previously, the Atlantic, Pacific and Indian Oceans were considered to extend as far as Antarctica, the name Southern Ocean did not exist. According to the National Ocean Service. The Southern Ocean is recognized by the US Organization of the US Board on Geographic Names as the water stretching from the Antarctic coast to the 60 degree south latitude line. The boundary of this ocean was proposed to the International Hydrological Organization (IHO) in 2000. This ocean name is widely recognized, however some organizations disagree. The Southern Ocean is 20.3 million square kilometers wide, equivalent to the area of ​​Russia and India combined. Coast stretches for nearly 18,000 km. The average depth is 4,000 – 5,000 m. The deepest point is in the South Sandwich Trench with a depth of 7,236 m. 2. Which ocean is the largest and the deepest? Icon Indian Ocean Icon Pacific Icon Atlantic The Pacific Ocean is the largest and deepest ocean on Earth. With an area of ​​165.25 million km2, this ocean accounts for one third of the total surface area of ​​the globe. All the land on Earth combined (about 150 million square kilometers) still cannot cover the surface of this ocean. The Pacific Ocean stretches from the Arctic Ocean in the north to the Antarctic continent in the south. The widest east-west width is 19,800 km, separating Asia, Oceania from the Americas. The Pacific Ocean has an average depth of 4,280 m. The deepest point of the ocean lies in the Mariana Trench, 10,911 m deep. This is also the deepest point of the Earth’s crust, 13 times the height of the Burj Khalifa – the tallest building in the world in Dubai. If Everest could be placed on the bottom of the Mariana Trench, the world’s highest mountain would still lie underneath the Pacific Ocean. 3. Which ocean is the smallest? Icon southern Ocean Icon Atlantic Icon Arctic Ocean The correct answer is answer C: According to the National Ocean Service, the Arctic Ocean is the smallest ocean on Earth with an area of ​​nearly 14.1 million square kilometers. Even the smallest, it is still nearly 1.5 times larger than the US. The Arctic Ocean borders the United States (the Alaska region), Russia, Canada, Norway and Denmark (the Greenland region). The average depth of this ocean is about 1,205 m, the deepest point is 5,567 m. The Arctic Ocean is almost completely covered by ice most of the year. However, this ocean is not barren. When the ice melts, organisms and nutrients are released into the water. This promotes the growth of algae under the ice. These algae provide food for small organisms, zooplankton, and are a source of food for fish, squid, seals and whales. Some of these larger creatures become prey to polar bears. When the organisms under the ice die, they sink to the ocean floor and feed sponges, anemones and other bottom organisms. 4. Is the Atlantic Ocean larger than the Indian Ocean, right or wrong? Icon It’s correct Icon Wrong The correct answer is answer A: Kindy Data already has a comparison showing that the Atlantic Ocean has an area larger than the Indian Ocean. The Atlantic Ocean is 106.5 million square kilometers wide, covering 20.8 percent of the Earth’s total surface. The average depth is 3,646 m. The deepest point is in the Puerto Rico Trench, at 8,486 m deep. It is surrounded by America to the west, Europe and Africa to the east. The width from east to west is about 9,600 km. Meanwhile, the Indian Ocean is 70.56 million square kilometers wide, covering 13.8 percent of the Earth’s surface. The average depth is 3,963 m. The deepest place is Diamantina trench, 8047 m deep. To the north, this ocean is limited by peninsulas India, Pakistan and Iran, east by Southeast Asia (namely Myanmar, Thailand, Malaysia, Indonesia) and Oceania, to the west by Arab and African islands. The Indian Ocean opens in the south and is bordered by the Southern Ice Ocean. 5. How many tons of gold does the world’s oceans contain? Icon 10 million Icon 20 million Icon 30 millions The correct answer is answer B: Experts estimate that about 20 million tons of gold are still in the ocean. Experts confirm that 1 ton of ocean ore contains about 13 grams of gold, while on land, only 3 to 7 grams of gold per ton of ore. 6. In which sea area is volcanic activity concentrated? Icon South Pacific Icon Indian Ocean Icon Atlantic The correct answer is Answer A: 90% of all volcanic activity on earth is concentrated in the ocean with the largest concentration in the South Pacific. 7. What is the freezing temperature of the oceans about Celsius? Icon -10 degrees C Icon -5 ° C Icon -1.8 degrees C The correct answer is Answer C: Seawater freezes around −1.8 ° C (28.8 ° F). When the temperature of the water drops low enough, ice crystals form on the surface. 8. Which ocean contains the highest salt content in the world? Icon Pacific Icon Atlantic Icon Indian Ocean The correct answer is answer B: Which ocean is the most salty in the world? that is the Atlantic Ocean. In this barn, the average salinity is about 37.9 o / oo. In the Sargasso Sea in the North Atlantic Ocean is the region with the greatest salinity. The reason is that the temperature here is quite high and located far from the mainland, so it does not receive water from rivers and streams. The lightest seawater belongs to the Arctic and Antarctic regions. This is understandable, these are 2 areas with low temperature and continuous rainfall and ice melting.
