Scientists have long suspected that the elusive Greenland sharks lived for a long time. It turns out they were right! A new study has revealed that the world’s second largest carnivorous fish may have a lifespan of as long as 400 years. To put it in perspective, that is about twice that of the previously known longest-living vertebrate, the Bowhead whale, which is known to live for up to two centuries.

i think living for 400 years is amazing. The  greenland shark has lived through both world wars but never seen it happen, it makes me wonder how it has such a long life span & can it benefit human life expectency.Imagine that the fountain of youth, they never get cancer. Sharks have been on our oceans for over 400 million years. Some of the earliest sharks were discovered dating back to the Devonian age. Not only did sharks first appear 400 million yeas ago, they are still here today. They have survived 5 massive planet extinction events. These extinction events killed most life on earth. The last one around 65 million yeas ago killed the dinosaurs. But not sharks. They were here to stay.

Hi i'm here today to talk to you about earthquakes i hope you like it

Paragraph 1

Earthquakes are usually caused when rock underground suddenly breaks along a fault. This sudden release of energy causes the shock waves that make the ground shake. When two blocks of rock or two plates are rubbing against each other, they stick a little. They don't just slide smoothly; the rocks catch on each other. The rocks are still pushing against each other, but not moving.

Paragraph 2

After a while, the rocks break because of all the pressure that's built up. When the rocks break, the earthquake occurs. During the earthquake and afterward, the plates or blocks of rock start moving, and they continue to move until they get stuck again. The spot underground where the rock breaks is called the focus of the earthquake. The place right above the focus (on top of the ground) is called the epicenter of the earthquake.

Paragraph 3

Earthquake-like shock waves can also be caused by explosions underground. These explosions may be set off to break rock while making tunnels for roads, railroads, subways, or mines. These explosions, however, don't cause very strong shock waves. You may not even feel them. Sometimes seismic waves occur when the roof or walls of a mine collapse. These can sometimes be felt by people near the mine. The largest underground explosions, from tests of nuclear warheads (bombs), can create shock waves very much like large earthquakes. This fact has been exploited as a means to enforce the global nuclear test ban, because no nuclear warhead can be set off on earth without producing such shock waves.

Conclusion

I am terrified of earthquakes i don't like them
