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.

Typhoons produce tornadoes 


Typhoons and tornadoes are both turning tempest frameworks, yet as we noted over, the typhoon's more prominent size and more term make it more harming than a tornado. It just compounds an already painful situation that tropical storms likewise frame tornadoes, now and then days after landfall.

Tornadoes can shape when a storm hits land and begins to rot in the wake of abandoning its watery warmth source. This breakdown in the tropical framework sets up diverse wind speeds at distinctive elevations, bringing about wind shear that can bring about a tornado.

Most tornadoes shape in the external groups, however some have been found close to the inside. Indeed, specialists associate that some with the serious harm from a sea tempest eyewall may be the aftereffect of tornadoes.

Typhoons can evolve and strengthen

Tropical typhoons are called storms in the Atlantic and hurricanes in a few sections of the Pacific, however they're the same tempests. About a large portion of them in the North Atlantic and right around 33% of them in the Pacific in the long run transform into "extratropical violent winds." This doesn't mean they're additional exceptional. It implies they aren't controlled by warmth any longer.

After extratropical move, these twisters for the most part blur away rapidly. Notwithstanding, watch out amid the move time, when the tropical storm may heighten in light of the fact that its tapping both its warmth supply and the temperature contrasts.

Storms have tough restrictions

The savagery and vitality of storms are spectacular, however even these monstrous tempests must take after the tenets of material science. On account of the Coriolis impact, they need to turn a certain way. This impact likewise prevents them from intersection the equator. Another tenet is that if two or more violent winds are near one another, they can't consolidate; rather, they circle one another. This is known as the Fujiwhara impact. The twisters don't need to both be tropical; a Fujiwhara collaboration with a standard low weight framework is the thing that made Hurricane Sandy, which was taking off to ocean, turn back and hit the East Coast.Hurricanes likewise debilitate themselves by mixing the warm upper layer of the sea so much that it pulls up frosty water from the profundities. Since these tempests keep running on warmth, this icy water then prevents them from escalating and can even totally close them down.

Blue Lava Volcano

Volcanoes are very popular in Asia. Sometimes, they think volcanoes are beautiful, especially if  they bust out red, hot lava. However, this is a different kind. It has a different color, Many people wants to see this.

Ijen volcano in East Java contains the world's largest acidic scissure lake, known as Kawah Ijen, far-famed for its turquoise color. The active crater measurement 950x600 m is understood for its made sulphur deposits that ar being quarried.

The volcano is one among many active stratovolcanoes created over the twenty kilometre wide Ijen volcanic crater, the biggest volcanic crater in Java.

Eruptions from Ijen ar terribly venturesome attributable to the danger of the lake exhausting to make ruinous lahars.


The Ijen volcano complicated at the jap finish of Java consists of a bunch of little stratovolcanoes created at intervals the big 20-km-wide Ijen (Kendeng) volcanic crater. The north volcanic crater wall forms a outstanding bowed ridge, however elsewhere the volcanic crater rim is buried by post-caldera volcanoes, as well as Gunung Merapi stratovolcano, that forms the 2799 m section of the Ijen complicated. directly west of Gunung Merapi is that the celebrated traditionally active Kawah Ijen volcano, that contains an almost 1-km-wide, turquoise-colored, acid crater lake. Picturesque Kawah Ijen is that the world's largest extremely acidic lake and is that the website of a labour-intensive sulfur mining operation within which sulfur-laden baskets ar hand-carried from the crater floor. several different post-caldera cones and craters ar situated at intervals the volcanic crater or on its rim. the biggest concentration of post-caldera cones forms Associate in Nursing E-W-trending zone across the southern facet of the volcanic crater. occasional plantations cowl abundant of the Ijen volcanic crater floor, and tourists ar drawn to its waterfalls, hot springs, and dramatic volcanic scenery.
