Our earth is covered with beautiful sea, how much do you know about them? Scientists have explored only a small part of these waters, but we learned a lot from their efforts. What is a coral reef? Is the table salt the same as what was found in the sea? What do marine scholars do? We have summarized the amazing sea fact that children share in the classroom.
In addition, click the button of Google Slide Copy of all marine facts below!
1. The ocean covers 71 % of the surface of the earth.
These huge salt water contain 97 % of all water on the earth.
2. There is one sea of the world.
Scientists and geologists are divided into five different sections: the Pacific Ocean, Atlantic, Indians, Southern and Arctic Sea, but in reality there are only one sea.
3. The sea is smaller than the sea, and is usually partially surrounded by land.
The sea usually lands on several aspects. The Mediterranean is located between Africa and Europe. The Baltic Sea can be found in Northern Europe and Central Europe. There is a Caribbean Sea between North America, Central America, and South America.
4. Seawater is salty.
The salty taste comes from sodium chloride, a chemical substance dissolved in water. Our table salt is also sodium chloride, but it is a crystal.
5. The sea is deep and wide.
The average sea is usually over 2 miles in depth. However, the deepest part of the sea of the earth is the Pacific Mariana Trench, which is almost 7 miles!
6. There are many levels on the sea floor.
This may be one of the most interesting marine facts in this list. The easiest continental shelf runs along the end of the continent. They are late toward the deep part called the basin. At the bottom of the basin is a large and flat plain. Deep cracks on the seabed are called Trench.
7. Seawater is always moving.
The wind and other power move a large amount of seawater around the earth with a pattern called current. Watch this wonderful video.
8. The sea current may be cold even if it is warm.
The warm flow usually causes warm weather and rain, but cold flow often causes dry climate.
9. There is life at all levels of the earth of the earth.
Whether it’s a plant grown near the surface of the water or an animal swimming in a habitat, there are five major life zones, and many creatures are calling our hometown of our sea.
10. There are estimated 2.2 million animals living in the sea.
Most of them are invertebrates such as shrimp and jellyfish (animals without backbone). However, the truth is that the number is unknown, and scientists believe that 91 % of the ocean species are not yet classified!
11. Part of the smallest animal of the earth lives in the sea.
Animal plankton is very small, so you need a microscope to see them!
12. The biggest marine animal is a blue whale.
In fact, it is the biggest animal that I have lived on earth. There are two school buses! Watch this wonderful video to see the details of the Brook Jila.
13. There is an area called habitat in the sea.
They can actually be divided into two. In fact, it is a habitat of coast and the habitat of the ocean. The coast, the depth of the sea, and the distance from the temperature determine the types of plants and animals living in the sea area.
14. Coral reefs are a kind of marine habitat.
Coral reefs are one of the most diverse habitats on the earth! The skeleton of a small animal called polyps has been enhanced to give a house to a living polyp. When the polyp dies, there is more movement. Coral reefs are formed for thousands of years of this cycle.
15. The coral reef is like a rainforest of the sea.
They offer food and shelters to many kinds of sea animals. See this video about our coral kingdom in our world.
16. Most of the world’s oxygen is created by plant plankton and algae.
Through photosynthesis, they produce about half of oxygen oxygen and breathe in living creatures (including humans!).
17. The ocean stabilizes the climate by accumulating heat from the sun.
By moving the water around the world, the sea does not get too hot or too cold.
18. Approximately 171 trillion plastic is floating in the sea around the world.
This is just a plastic estimation value on the sea surface. The plastic sinking under the surface is not included. See that these children take action against marine plastic.
19. Both land and sea animals eat plastic.
The catastrophic truth is that 52 % of the sea turtles ate plastic trash. In one expedition, plastic was found in 20 % of the fish stomach.
20. Marine pollution reduces oxygen in water.
Plastic contamination exists in the sea and destroys bacteria seeds that cause oxygen. This is one of the most important sea facts for your child. We all need to play our role to protect our sea!
21. Marine scholars study the sea and keep them healthy.
Marine scholars monitor how water moves, look at the structure of the basin and seabed, examine the quality of the water, and study plants and animals living in the sea.
twenty two. We are only searching for 5 % of the sea.
Considering that the ocean covers about 70 % of the earth, we have a long way to go to know our sea! Will you be the next marine scholar who finds underwater grooves and new species? See this cool video about Ocean Explorer!
23. The Pacific Ocean is the largest sea on the earth.
It covers more than 30 % of the surface of the earth!
24. The Arctic Sea is the smallest sea on earth.
The Arctic Arctic, located in the Arctic, is not only the smallest but also the shallow sea. This is one of the coldest sea facts for children!
25. The longest mountain can be found underwater.
This shares facts about the sea and mountains! South America’s Andes is 8,900 kilometers (5,530 miles) and is known as the longest mountain on land. A much larger central ocean ridge was found in water, and the length was about 65,000 kilometers (40,389 miles). It’s huge!
26. The ring of fire is a frequent earthquake and volcanic activity area in the Pacific Ocean.
Ring of Fire contains many trenches, including famous Mariana trenches, which have the deepest places on the earth.
27. The Atlantic Ocean is slightly larger than half the size of the Pacific Ocean.
The Atlantic Ocean covers about one -fifths of the earth’s surface, despite the second largest and 27,493 feet depth.
28. The Pacific name has the source of calmness.
This name, named by Explorer Ferdinand Magellan, is derived from Tepre Pacificum, a Latin word of “peaceful sea”.
29. The Pacific Ocean is on the boundary of more than 50 countries!
This is one of the most amazing and fun facts about the sea. The Pacific Ocean is so large that it makes sense to touch so many countries, including Australia, Chile, Japan and the United States.
30. Titanic sank into the Atlantic Ocean.
A famous ship sank off the coast of Novascosia, Canada. More than 1,500 passengers died.
31. The warmest sea is the Indian Ocean.
With the warmth of the Indian Ocean, water evaporates faster than other oceans, making it difficult for plant plankton to survive.
32. The youngest sea is the South Sea.
The Southern Sea (also called Antarctica), formed when the Antarctic continent split from South America and Australia is about 30 million years ago. Also, this process has formed a famous drake passage (see this video about what crosses the drake passage while sharing these sea facts for children)!
33. There are five names on the earth. The Pacific Ocean, the Atlantic, India, the Arctic, and the Nankai Sea.
Scientists recognize the sea in one world, but they are geographically divided into five names.
34. Sperm whales sleep upright in the sea and sleep.
The magnificent sperm whales maintain the vertical position during 10 to 15 minutes. It doesn’t sound very peaceful for humans!
35. The Atlantic Ocean first crossed in both air and the sea.
Vikings and explorers found the road beyond the Atlantic Ocean, but the ocean liner began to intersect in the early 1800s. In 1919, Captain John Alcock and Arthur Witten Brown were the first LI of the Atlantic Ocean!
36. The ocean absorbs carbon dioxide from the atmosphere.
The ocean is useful for regulating the earth’s climate by absorbing about 30 % of the carbon dioxide (CO2) released by humans in the atmosphere.
37. In the deep sea, there is a biological light -emitting creature.
It is estimated that 90 % of animals living in more than 500 meters below the ground (1,640 feet) are biological light (light light). This must be one of the most amazing sea facts for children! Creatures that are commonly found in the ocean belt contain jellyfish, shrimp, squid and fish.
38. The Indian Ocean covers about 20 % of the surface of the earth.
The third largest Indian Ocean of the five oceans is about 5.5 times the size of the United States!
39. Large Pacific barriers can be seen from space.
After all, it is the biggest living structure on the earth!
40. The ocean hot water hole may reach the temperature exceeding 750 ° (400 ° C).
The hot water hole is seen along the central ocean ridge and emits abundant water that supports unique ecosystems.
41. There are underwater lakes and rivers in the sea.
They are formed that seawater is “to penetrate the thick salt layer under the seabed.” oh!
42. The marine pressure increases along with the depth.
When you think about it, it makes sense -the deeper you go under the sea, the greater the pressure from the water pushed down on your body!
43. The huge kelp forest in the sea provides an important habitat.
These kelp forests offer thousands of marine species of shelters, nursery schools, and food.
44. The biggest sound in the animal kingdom comes from a whale.
If it is considered to be the most noisy animal on the earth, sperm whales can create as loud sound as 230 decibels. This is bigger than a jet engine or rocket launch!
45. The sea surface has risen by about 8 inches since 1880.
This rising is because the climate changes, causing seawater to expand, causing melting of ice on land such as glaciers and polar ice caps.
46. The sea contains underwater volcanoes.
Hot water holes and underwater volcanoes are scattered along the middle ridge, contributing to the unique ecosystem of the deep sea. Learn more about what will happen when a large -scale underwater volcano erupts!
47. Some marine animals move thousands of miles every year.
Seeds like seaweed whales and leather back sea turtles embark on magnificent movements and move thousands of miles to propagate, feed, and escape cold water. Find out why these migratory birds are now very dangerous.
48. The sea is the home of the world’s largest living structure.
The Great Barrier Leaf is more than 1,400 miles from the Australian coast and is composed of billions of small creatures called coral polyps.
49. The sound moves in the water faster than the air.
In the sea, the sound moves much faster than the air, making it an essential tool for long -distance marine animals such as dolphins and whales.
50. The sea adjusts the temperature of the earth.
By absorbing and distributing the heat around the world, the ocean works like a thermostat in the world, stabilizes the climate of the planetary, and prevents extreme temperature fluctuations. See more about how the sea affects the land climate and weather.
51. There is a unique “desert” in the sea.
Because of the very low nutritional level, there are areas called Ochangeia, which has a very low nutritional level that can create biological “dead zones”.
52. You can find underwater waterfalls in the sea.
The largest one is the Danish Strait Cultivar. There, it flows under hot water, which is cold and dense, and creates a higher waterfall effect than land. This is one of the wildest sea facts for children!
53. I don’t know much about the sea floor than knowing the surface of Mars.
Despite the advancement of technology, only about 20 % of the sea floor is mapped at high resolution, many of which are still mysterious. Good news? UNESCO has promised to map 80 % by 2030!
