The Forgotten Lands Under The Sea

A great many years prior, the world was one major landmass. Over the long haul, the supercontinent of Pangaea separated into littler mainlands, which then likewise broke into littler landmasses. Today, we're all acquainted with the plan of the Earth's parts—in any event, regarding the terrains over the surface of the sea.

The Lion City 

China's Shicheng, "the Lion City," has been named the Atlantis of the East. In any case, not at all like Atlantis, Shicheng is totally genuine and stunningly wonderful. Situated in Zhejiang Province, the city was more than a thousand years of age when it was purposely overflowed in 1959 amid the development of the Xin'an River Hydropower Station. More than 300,000 occupants must be moved from the city, which is without further ado under Lake Qiandio.

The Lion City has been named a "period case" by archeologists, since the waters have impeccably saved a large number of its old structures, and in addition stone carvings from the Qing and Ming lines. Five doors lead into the Lion City, rather than the four ordinary of other Chinese urban areas; the dividers themselves go back to the 16th century.

Sundaland 

Another microcontinent right away submerged, Sundaland is situated in what is presently southeast Asia. It was the single biggest territory of area submerged after the last ice age, sinking around nineteen thousand years prior after frigid decrease created the ocean level to ascend by approx. 100 m.

At the point when Sundaland was still over the water, it was double the extent of India, extending from Burma to Borneo and including present-day Malaysia and Indonesia. Actually, Sundaland signed up all the islands of advanced southeast Asia into one extraordinary area, extending the distance to the Philippines.

Obviously, Sundaland has been connected to Plato's popular legend of Atlantis, in spite of the fact that it has additionally been connected to the just as fabulous landmass of Lemuria. One creator even claims that the Garden of Eden was really situated on Sundaland.

The Ocean Noise We Hear from Sea Shells

OK, first things first: regardless of the amount it may sound like the moving waves, its not really the sea you're hearing in a shell.

Since we've got that off the beaten path, what precisely is it that you're hearing? In a word, clamor; the encompassing commotion that is being delivered all around and inside you, which you typically don't hear or pay consideration on in light of the fact that its too peaceful.


To open up this commotion so you can hear it obviously, you require a resonator. Need to make one at little to no cost? Structure an O shape with your mouth and flick your finger against your throat or cheek. You ought to hear a note. Make a littler or bigger O, or change the state of your mouth, and you'll get diverse notes. Kind of like this. What you're doing here is letting your mouth satisfy its potential as a Helmholtz resonator, where sound is delivered via air vibrating in a hole with one opening. Diverse pitches can be cajoled out by changing the state of the reverberating cavity.

The seashell you're listening to within which has some hard, bended surfaces incredible for reflecting sound—is basically doing likewise you simply did with your mouth. The encompassing clamor specified before—the air moving past and inside of the shell, the blood coursing through your head, the discussion going ahead in the following room—is resounding inside the pit of the shell, being opened up and turning out to be sufficiently clear for us to notice. Much the same as the different shapes we make with our mouths will deliver diverse pitches, distinctive sizes and states of shell sound diverse on the grounds that distinctive resounding loads will intensify diverse frequencies.

The way that all shells sound only a tiny bit like the sea is simply unplanned. Holding any kind of Helmholtz resonator to your ear will deliver a comparative impact.
