Hello friends, welcome to a new Happy Learning video. Today we are going to learn what the biggest and most violent storms are, hurricanes.

Hurricanes are so called because according to the Mayan legend a God named Hurakan spread his breath through the water creating the Earth.

But that is only a legend. Hurricanes are really huge tropical storms that form in the southern Atlantic Ocean, in the Caribbean Sea and in the Gulf of Mexico. Depending on where they are formed they are also called cyclones or typhoons. For example, hurricanes that form in the Pacific Ocean are called Typhoons and those that form in the Indian Ocean cyclones.

Hurricanes are formed by an eye or centre composed of calm air that is surrounded by clouds, strong winds and storms full of water.

 Hurricanes form when a series of electrical storms come together and travel over the warm waters of the oceans. The warm air of the storm causes surface water to evaporate and begin to rise generating low pressure on the surface of the ocean.

The winds that circulate in opposite directions make the storm begin to turn. The rise of the warm air causes the pressure to decrease at higher altitude so that the air rises faster and faster to fill that space of low pressure, attracting more warm air from the sea surface and expelling the coldest air. and dry down.
As the storm moves across the ocean, the speed of the wind increases and it takes an enormous and incredible force, until the hurricane forms.

When it hits the ground, the impact of a hurricane usually causes a lot of damage although it depends on the category of hurricane as it is classified in 5. Category 1 hurricanes are the weakest and have a speed between 119 and 153 kilometers per hour. Those of category 5 go to more than 250 kilometers per hour and are super destructive.

The truth is that hurricanes are very dangerous and there are populations that have been destroyed by them. At present scientists, do not know if global warming causes more hurricanes or not but if they are clear that it greatly increases its intensity and its destructive power. So, as we always tell you from Happy Learning, you have to take care of the planet, you have to recycle and contaminate as little as possible. If we all respect nature, we will avoid many misfortunes and sorrows.

Did you know that the biggest shark that has ever existed was the megalodon?
This gigantic beast had a length of 20 meters and weighed 20 tones! The megalodon lived nearly 20 million years ago and disappeared 2 million years ago. It is considered as one of the most powerful predators of history of the vertebrates and their favorite prey where sea mammals such as whales or dolphins. It is a shame that the megalodon has disappeared but to be honest, it would have been really scary. By the way, did you know that its name originated from Latin and it means ‚ÄėBig tooth‚Äô?

Did you know that sharks can have thousandths and thousandths of teeth in their life time?
Sharks have their denture distributed in layers. when a tooth breaks, immediately, it is replaced by the layers above.
In general sharks have between 5 and 15 lines of teeth, although the first line is the most important, and it is what they usually eat their prey with. Many scientists have assured us that sharks can have up to 30 million teeth during their life

Did you know that sharks don’t stop swimming, not even for when they need to sleep?
This is because of wo reasons. The first is because of their breathing. Whilst sharks swim, they maintain their mouth open, this way the water that contains a lot of oxygen, passes through their gills and absorbs the oxygen to be able to breath. The second reason is that, differently from all fish, sharks don’t have a swim bladder a kind of internal float that fills with air and allows them to float even though they are still. It sounds weird but it is true, if a shark stops swimming it will fall to the bottom of the ocean and drown. Although the sleeping fish is eaten by the shark…..
