THE OFFICIAL EARTH'S HISTTORY THE AGE OF THE EARTH




Meteorological Phenomena Raining Animals.

Raining animals is agreed to be a rare meteorological phenomenon in which flightless animals are said "to rain" from the sky. Such occurrences have been reported to happen in many countries throughout history. One hypothesis offered to explain this phenomenon to take place when strong winds traveling over water sometimes pick up creatures such as fish or frogs, and carry them for up to several miles. Sometimes the animals are known to survive the fall, suggesting the animals are dropped shortly after extraction. Several witnesses of raining frogs describe the animals to move, to be startled, though healthy, and exhibiting relatively normal behavior shortly after the event. In some incidents, however, the animals are frozen to death or even completely encased in ice. There are examples where the product of the rain does not seem to be intact animals, but shredded body parts. Some cases occur just after storms having strong winds, especially during tornadoes. However, there have been many unconfirmed cases in which the eyewitnesses said the rainfalls of animals to have occurred in fair weather and in the absence of strong winds or waterspouts.

EARTHQUAKE LIGHT

An earthquake light is an unusual luminous aerial phenomenon that reportedly appears to be seen in the sky at or near areas of tectonic stress, seismic activity, or volcanic eruptions. The lights are reported to appear while an earthquake is occurring, although there are reports of lights before or after earthquakes, such as reports concerning the 1975 Kalapana earthquake. If we were the eyewitnesses of these lights, we would see them have shapes similar to those of the auroras, with a white to bluish hue, but occasionally they have been reported having a wider color spectrum. The luminosity is described to be visible for several seconds, but has also been reported to last for tens of minutes. The scientists consider this phenomenon to be caused by intense electric fields created piezoelectrically by tectonic movements of rocks containing quartz.
AVALANCHES

Most avalanches are considered to represent small slides of dry powdery snow that move as a
formless mass. While avalanches are known to have a sudden character, the scientists notice

numerous warning signs appear before they let loose. Yet in 90 percent of avalanche incidents, the snow slides are triggered by the victim or someone in the victim's party. The statistics state avalanches to kill more than 150 people worldwide each year. Most are snowmobilers, skiers, and snowboarders. If all necessary safety precautions were made in time, many human lives would be able to be saved.

HURRICANES

Hurricanes are agreed to represent giant, spiraling tropical storms that can pack wind speeds of over 160 miles (257 kilometers) an hour and unleash more than 2.4 trillion gallons (9 trillion liters) of rain a day. These same tropical storms are known to be called cyclones in the northern Indian Ocean and Bay of Bengal, and as typhoons in the western Pacific Ocean.

LIGHTNINGS

Cloud-to-ground lightning bolts are considered to be a common phenomenonabout 100 strike Earth's surface every single second. Yet if we could measure their power, it would prove to be extraordinary. This enormous electrical discharge seems to be caused by an imbalance between positive and negative charges. During a storm, colliding particles of rain, ice, or snow are considered to increase this imbalance and often negatively charge the lower reaches of storm clouds. Objects on the ground, like steeples, trees, people and the Earth itself, become positively chargedcreating an imbalance that nature seeks to remedy by passing current between the two charges. The process forms a channel through which electricity is transferred as lightning.

FLOODS

A flood will occur if water overflows or inundates land that's normally dry. Most common way of creating a flood is believed to take place when rivers or streams overflow their banks.

VOLCANOES

Volcanoes may be considered as awesome manifestations of the fiery power contained deep within the Earth. These formations are essentially vents on the Earth's surface where molten rock, debris, and gases from the planet's interior are emitted. Were thick magma and large amounts of gas built up under the surface, eruptions would be explosive, expelling lava, rocks and ash into the air. Had these eruptions less gas and more viscous magma they would be regarded to have less dramatic consequences, often causing streams of lava to ooze from the vent.

THE OFFICIAL EARTH'S HISTTORY THE AGE OF THE EARTH

The age of Earth is supposed to total approximately one-third of the age of the universe. The earliest material found in the Solar System is scientifically proved to be dated to 4.56720.0006 billion years ago; therefore, it may be inferred that the Earth must have been forming by accretion around this time. By 4.540.04 billion years ago the primordial Earth is sure to have formed.

The formation and evolution of the Solar System bodies is presumed to have occurred in tandem with the Sun. In theory a solar nebula must have partitioned a volume out of a molecular cloud by gravitational collapse, which began to spin and flatten into a circumstellar disk, and this caused the planets to grow out of the disk in tandem with the star. The adherers of the nebular theory believe planetesimals to commence forming as particulate accrues by cohesive clumping and then by gravity. The assembly of the primordial Earth might have been proceeding for 10-20 million years ago. The Moon is considered to have formed shortly thereafter, about 4.53 billion years ago. If we began discussing the Moon's formation, we would have to admit it to remain a mystery.

 

EARLY EARTH'S HISTORY

 

Volcanic outgassing on the Earth is likely to have created the primordial atmosphere, but it contained almost no oxygen and would have been toxic to humans and most modern life. The official science states much of the Earth to have been molten at that era because of extreme volcanism and frequent collisions with other bodies. One very large collision is thought to have been responsible for tilting the Earth at an angle and forming the Moon. Over time, such cosmic bombardments ceased, allowing the planet to cool and form a solid crust. Water that is agreed to have been brought here by comets and asteroids condensed into clouds and the oceans took shape. Earth was finally hospitable to life, and the earliest forms that arose enriched the atmosphere with oxygen. Life on Earth must have remained small and microscopic for at least one billion years. About 580 million years ago, complex multicellular life arose, and during the Cambrian period it experienced a rapid diversification into most major phyla. Around six million years ago, the primate lineage that would lead to chimpanzees (the closest relatives of humans) diverged from the lineage that would lead to modern humans. Biological and geological change has been constantly occurring on our planet since the time of its formation. Organisms continuously evolve, taking on new forms or going extinct in response to an ever-changing planet. The process of plate tectonics has played a major role in the shaping of Earth's oceans and continents, as well as the life they harbor.

The biosphere, in turn, has had a significant effect on the atmosphere and other abiotic conditions on the planet, such as the formation of the ozone layer, the proliferation of oxygen, and the creation of soil. Though humans are unable to perceive it due to their relatively brief life spans, this change is ongoing and will continue for the next few billion years.
