We help you answer your child's curiosities and questions about the oceans. Find here answers to children's whys about the ocean.
Seeks surprising answers to children's most complex questions about the ocean. Here are some:
- Why does it seem that the sea disappears for a few hours and reappears later? Yes, have you ever gotten up one morning and discovered with amazement that the sea, which reached the end of the beach, has 'disappeared'. The blame for this mysterious event is the tides.
- And what are the tides? The sun and the moon exert forces of gravity on the Earth. You already know that gravity is that force that attracts objects to a certain point. In this way, the force of gravity of the moon and the sun, drag the water currents, causing them to move to one side and then to the other. This is how the tides are produced. The force of gravity exerted by the moon is greater than that of the sun. That is why it is often said that the moon is the 'culprit' that the sea disappears. When the sea seems to disappear we speak of low tide or low tide. When it reappears, we speak of high tide or high tide.
- What is in the ocean? Do you know that we probably know more about planets like Mars than about our own ocean? It seems incredible, but 95% of the oceans remain unexplored. It is so deep that there are many places where man has not been able to reach. At a certain depth the pressure is so high that man cannot bear it, so it could only be reached ... a machine!
- So can there be species that we don't know about? Yes ... and many !! For example, it is estimated that there are almost a dozen species of dolphins and whales that we do not know about.
- And what is the seabed like? Is flat? Do not!! In fact, it is like the surface, with mountains, volcanoes, earthquakes and even waterfalls.
- Can there really be waterfalls under the sea? Yes. Up to 7 underwater waterfalls are known. But surely there will be many more ... Some are in Mauritius. They occur when the cold wind cools the surface of the water and it increases in density. As they increase in density, they sink, and form a waterfall if when sinking they find a deep canyon. The optical effect is that of an immense cataract.
- And how many species are there in the water? 100? No, many more. More animals live under water than on land. In fact, it is estimated that marine species represent 94% of the total species on the planet. Almost all!
- And is it true that many treasures are accumulated in the sea? Yes. Treasures and objects of ancient civilizations. In fact, the ocean might be the largest and most valuable museum in the world.
- And the mermaids and giant octopuses that appear in the books exist? There is a lot of talk about a giant octopus named Kraken. It is actually fantasy, a legend, like that of mermaids. But everything is based on real events. For example, the famous Kraken octopus is based on marine animals that inhabited the ocean in the Triassic period. There were huge octopods.
- And the mermaids? Mermaids arose from an Assyrian legend, but many sailors claim to have observed them ... They represent them as a dolphin with a woman's bust. They are protagonists throughout the history of countless literary works. The most famous are surely the mermaids from the book 'Ulysses'. Could it be one of those marine species that we still don't know about?
