The enchantment of Indonesian submarine

Feel the sensation when the body surf in the collection of small to giant-sized reefs that grow in sandy seabed, coral walls along tens of meters, followed by a lively movement of a variety of reef fish and marine life forms and colors with a gorgeous body. If you want to feel like Superman flying, you do not need to fantasize about having wings. Indonesian underwater world can realize your desire to fly the most beautiful places on this planet. Panorama that can easily be found in this maritime country. With a length of 95.181 kilometers of the coast or the second longest in the world, humble surge with a variety of reef fish on the surface and bottom water, cave, up the mountain under the sea. Waters of Bunaken Island, North Sulawesi is a small example of the nirvana that. Divers can be passed with exotic fish, such as Napoleon wrasse (Cheilinus undulatus), and a giant green turtle (Chelonia mydas). On the beach Hukurila in Ambon, Maluku, and Wasage Beach on the island of Buton, Southeast Sulawesi, fans adrenaline challenge will be presented with views of caves under the sea.

In the southwest, Mangehetang Island, Sangihe, North Sulawesi, the diver can see underwater mountain at a shallow enough waters to the point of the mountain crater eight meters deep. Banyknya almost countless dive sites that exist in the homeland of Indonesia. The potential is so vast and each point offering spectacular diving underwater unique and different. Diving tours in the homeland Indonesia started developing since the early 1980s. Special interest also led to the birth lovers of diving clubs, and tourist resort with dive operators service offering objects with tremendous experience. With the emergence of diving tourism objects, the interest of society to recognize this sport continues to grow. The growing interest of the community was at least as reflected in the exhibition Indonesia and Extreme Deep Indonesia 2010 in Jakarta on March 12-14 ago. With 20.000 rupiahs admission per person, from morning until night thousands of visitors from inside and outside the country crowded the booth stores tools sellers and agents, scuba diving tours.

If countries in mainland Europe is able to stimulate tourists to the exoticism of their artificial construction, not an overstatement that dive tour operators and tourist resort services raise sea superiority in these equatorial countries, namely Indonesia.

The Age of Earth

Geologists have calculated how much the age of the earth. This can be estimated from the level of damage from a few specific elements that existed at the Earth's crust. Atoms of uranium and thorium the longer the less, changing gradually into a variety of elements including radium which ended up being a black tin atoms. Rate this change has been investigated in the laboratory, how long of an element into another element. Elements downsizing it happens regularly.

The stones of the mountain or archaeological objects can be used as a tool to calculate the ratio of mineral elements such as lead, uranium, radium, so that can know a lot of comparisons and the reduction of the investigated objects, then they will know how long the reduction process, and thus also be shown how the stone age. Similarly age of the earth can be known in a similar way. They estimate the age of the earth between 3000 to 5000 million years ago. The calculation can be done any other way to calculate how much salt is contained in the oceans today.

The experts firmly believe that when at first there was the ocean, the water is not salty. What causes sea water taste salty is because the rivers that come from the mainland brought a variety of substances that make the sea water became salty taste. After carefully calculated how much salt water content is increased every year, so know how old the earth. Among all the planets in this solar system, only allowing the existence of life. Nevertheless, still uncertain whether other planets have life, though different from what exists on earth.

Doubts were depicted on American spacecraft, Voyager II, which was launched on 20 August 1977 to Jupiter, Saturn, Uranus and perhaps then he would shy away from the solar system to the next adventure for for about 1000 million years between the stars in the Milky Way. On the plane, played the messages from the President of the United States and prosperous congratulations sayings from various nations of different languages who knows maybe there is a civilized life. Reaction of civilization would be provoked in this way. The leading scholars, both her undergraduate astronomy, geology or biology. All agreed that life on this earth that life runs in evolution or a gradual slow. It means that now is not the same man to man hundreds of thousands of years ago. It is also not the same shape of the animal's body is now with the animals millions of years ago. Origin of life is from one cell, which then evolve rapidly.

These cells then transformed into plants or animals like this now. Change is a very long time consuming. Forms of life on earth in accordance with the terms and conditions that owned the earth. Similarly, life on earth will end when the terms and conditions do not permit the earth again. For example if it was time the sun was enlarged, so the bigger of the sun so very close to the earth, of life on earth ended. What is the most difficult questions to be answered is the biggest question of all time is where the sudden advent of life or soul of a cell. If the theory of evolution's way of thinking can make a sense, but the arrival of life or soul for animals, plants and humans are not answered by these scholars.

Layers of earth

Like the sun, stars or planets all in layers, so even this is our earth. If the earth is split, it will be visible outside parts as follows:

• Earth's crust, which is the outermost skin, thickness between 16 to 40 kilometers. On top of this skin live all living creatures on land, sea and air. In this skin saved all the materials such as gold mining, coal, kerosene and others.
• Underneath a thick layer of approximately 2280 kilometers. A hard layer, an inner skin. The inner skin is much thicker than the outer skin. If we suppose the earth as a mango, mango meat we eat is in the earth's skin. In this part is wrapping the earth's core.
• Outer core of the earth, which is 2208 kilometers thick. This core is a liquid core. This can be known from an earthquake wave propagation. Earthquake can not be through the watery part of the earth in the center of the earth.
• Deepest layers that form the core, thickness 1248 kilometers. It's in very hard circumstances. This is really the core of the earth with a radius of 1248 kilometers or with a diameter of 2496 kilometers.

Temperatures at the Earth's crust under the increasingly rising every 100 feet down, the temperature increased one degree Celsius. It is known from excavations of kerosene. If this was used as a basis to determine how the central temperature of the earth, it will get the number for 290 000 degrees Celsius. Thus the high temperature at the earth's center, not at all unreasonable. It may well be not the same rate of temperature increase with the number increasing in the Earth's crust. Suspicion in the center of the earth temperature is around 5550 degrees Celsius.
