However, as the researchers found that the age of the Earth is just 4.54 billion years? In fact, it was very difficult to determine the age of the planet based on an examination howl at the moon chicago of its surface, howl at the moon chicago because plate tectonics constantly changing its character. The oldest part of the earth slipped beneath the tectonic plates and recycled inside her. On our planet could not be found the remains of rocks older than 4.4 billion years. Some theories of history to us today may therefore quite fun ...
French anthropologist Benoît de Maillet howl at the moon chicago (1656-1738) was - wrongly - assumed that the occurrence howl at the moon chicago of fossils of marine animals at high altitudes means that the whole Earth in ancient howl at the moon chicago times covered by the vast ocean. According to his theory took two billion years for the water to evaporate at the current level. Scientists thought to have left when they realized that the sea level may naturally fall as well as rise.
French naturalist Georges-Louis Lecterc (1707-1788) attempted to determine the age of the earth based on the rate of cooling. He studied the cooling rate of the metal balls, the size compared to the size of our planet. It concluded that the Earth must have originated about 75 thousand years ago.
William Thompson (1824-1907), later known as Lord Kelvin, assumed that the Earth formed long ago melted stone ball about the same temperature as the sun and gradually felt more. Subsequently, he calculated that the planet took about 20-400 million years before reaching the current temperature. Thompson, however, made several erroneous assumptions, eg concerning the temperature of our star (the actual temperature at its core is 15 million degrees) and planet (including molten core). Sun consists mainly of hydrogen, the Earth again from various rocks and metals.
In 1856, the German physicist Hermann Ludwig Ferdinand von Helmholtz (1821-1894) attempted to calculate the age of the earth through a gradual cooling of the sun. He concluded that our star took 22 million years to the stage diffuse cloud of gas and dust, "helped me" to its current size and temperature. Although the mentioned result is not accurate, Ferdinand von Helmholtz correctly determined that the source of energy in the initial stage of development of the young Sun was particularly its gravitational contraction.
In the book The Origin of Species by Means of Natural Selection proposes Charles Darwin (1809-1882) to calculate the minimum age of our planet based on the erosion of deposits of the Cretaceous Period. Known naturalist estimated that Cretaceous formations in England region howl at the moon chicago Weald could do to weather the current form about 300 million years.
English howl at the moon chicago geologist John Phillips (1800-1874) used to estimate the age of the earth deposited sediments and reached the value of 38-96 million howl at the moon chicago years. This method howl at the moon chicago compares the measured velocity continental erosion with a total thickness of sedimentary rocks and in successive howl at the moon chicago time-separated layers in succession.
American geologist and paleontologist Charles D. Walcott (1850-1927) probably the most famous, thanks to its discovery and subsequent research of Canadian fossils. Prepared most detailed model the deposition of sediments and determine the age of the earth at 35-80 million years.
George Darwin (1845-1912), son of Charles Darwin, estimated that the moon could arise out of the country and gradually move away from it to the current location. According to that theory, as a result of the rapid rotation of the planet seceded and "flew" into space. Darwin younger calculated that month needed 56 million years to reach its present position. howl at the moon chicago But now we know that most likely originated in a collision with Earth-sized bodies of Mars shortly after its inception and is currently howl at the moon chicago speeding away from us almost four centimeters per year.
The German philosopher Immanuel Kant (1724-1804) was first recognized by the disturbing effect of tidal forces on Earth's rotation. Tides cause i really slowing howl at the moon chicago rotation of our planet howl at the moon chicago and the moon moves away. Earth day is thus extended by about 2.3 milliseconds per year, and our companion is moving away from us annually by an average of 3.7 centimeters.
Significant astronomer Edmund Halley (1656-1742) proposed to use to determine the age of our planet howl at the moon chicago salinity (saltiness) oceans. Came from the fact that the oceans are within the natural water cycle powered by streams of water, howl at the moon chicago which they constantly add new and novel salt. Over time, as the ocean becomes slanějším, which allows you to specify how long that process takes place. Various geologists on the basis of those methods estimate that the age of the Earth is 80-150 million years. The procedure proved to be wrong: The scientists did not realize howl at the moon chicago that the various geological processes of salt water also collected.
