Cretaceous period

The Cretaceous is geologic period and system that spans 79 million years from the end of the Jurassic period 145 million years ago to the beginning of the Paleogene Period 66 mys. It is the last period of the Mesozoic Era and the longest period of the Phanerozoic Eon. The Cretaceous Period is usually abbreviated K, for its German translation Kreide (chalk, creta in Latin) . The Cretaceous was a period with a relatively warm climate, resulting in high eustatic sea levels that created numerous shallow inland seas. These oceans and seas were populated with now-extinct marine reptiles, ammonites and rudists, while dinosaurs continued to dominate on land. During this time, new groups of mammals and birds, as well as flowering plants, appeared . Research History :- The Cretaceous as a separate period was first defined by Belgian geologist Jean d'Omalius d'Halloy in 1822, using strata in the Paris Basin and named for the extensive beds of chalk (calcium carbonate depo

ALIEN

                                           ALIEN                                          "ALIEN" is a Extraterrestrial life which may occur outside of the earth. Why we are named Extraterrestrial life as Alien is because the word Alien describes a foreigners that mean's they are outsiders. The word Alien is not new to human's in the history so many ancient civilizations mentioned that Extraterrestrial people visited the earth in their books and painting's but no one knows it is true or not there are so many questions about Aliens. The information in this post is what i'm thinking i don't say it was correct but it was my perspective.             1) The Existence of ALIEN Civilization  :-                                                  The Extraterrestrial life (Alien Civilization) is not exited for now it is just assumption but we are thinking that there may be a chance for existence of life in other planets some where else in the universe. 2 )   ALIENS

Red rain

The Kerala red rain phenomenon was a blood rain event that occurred from 25 July to 23 September 2001, when heavy downpours of red-colored rain fell sporadically on the southern Indian state of Kerala, staining clothes pink. Yellow, green, and black rain was also reported. Coloured rain was also reported in Kerala in 1896 and several times since, most recently in June 2012, and from 15 November 2012 to 27 December 2012 in eastern and north-central provinces of Sri Lanka.                   Following a light microscopy examination in 2001, it was initially thought that the rains were colored by fallout from a hypothetical meteor burst, but a study commissioned by the Government of India concluded that the rains had been colored by airborne spores from a locally prolific terrestrial green alga from the genus Trentepohlia. an international team later identified the exact species as T.annulata.     Occurrence :-    The colored rain of Kerala began falling on 25 July 2001,

Solid State Drive(SSD)

We’ll make no assumptions here and keep this article on a level that anyone can understand. You might be shopping for a computer and simply wondering what the heck SSD actually means? To begin, SSD stands for Solid State Drive. You’re probably familiar with USB memory sticks - SSD can be thought of as an oversized and more sophisticated version of the humble USB memory stick. Like a memory stick, there are no moving parts to an SSD. Rather, information is stored in microchips.  Conversely, a hard disk drive uses a mechanical arm with a read/write head to move around and read information from the right location on a storage platter. This difference is what makes SSD so much faster. As an analogy, what’s quicker? Having to walk across the room to retrieve a book to get information or simply magically having that book open in front of you when you need it? That’s how an HDD compares to an SSD; it simply requires more physical labor (mechanical movement) to get information. A typical S

Nibiru cataclysm

The  Nibiru cataclysm  is a supposed disastrous encounter between the Earth  and a large planetary object (either a collision or a near-miss) which certain groups believe will take place in the early 21st century. Believers in this doomsday event usually refer to this object as  Planet X  or  Nibiru . The idea that a planet-sized object will collide with or closely pass by Earth in the near future is not supported by any scientific evidence and has been rejected by astronomers and planetary scientists as pseudoscience and an Internet hoax. The idea was first put forward in 1995 by Nancy Lieder, founder of the website ZetaTalk. Lieder describes herself as a contactee with the ability to receive messages from  extraterrestrials  from the Zeta reticuli star system through an implant in her brain. She states that she was chosen to warn mankind that the object would sweep through the inner  Solar System  in May 2003 (though that date was later postponed) causing Earth to undergo a physi

Dark matter

Dark matter  is an unidentified type of matter  distinct from dark energy ,  baryonic matter  (ordinary matter),  and neutrinos . It comprises approximately 27% of the  mass and energy  in the   observable universe .  The name refers to the fact that it does not emit or interact with electromagnetic radiation , such as light, and is thus invisible to the entire electromagnetic spectrum .  Although dark matter has not been directly observed, its existence and properties are inferred from its gravitational effects such as the motions of visible matter, gravitational lensing , its influence on the universe's large-scale structure , and its effects in the cosmic microwave background . Dark matter is transparent to    electromagnetic radiation  and/or is so dense and small that it fails to absorb or emit enough radiation to be detectable with current imaging technology.                                  Estimates of masses for galaxies and larger structures via dynamical and 

Tectonic Plates

Tectonic plates are pieces of earth's crust and uppermost mantle,together referred to as the lithosphere.The plates are around 100 km (62 mi)thick and consist of two principal material:ocean -crust(also called sima from silicon magnesium) and continental crust (sial from silicon and aluminium).The composition of the two types of crust differs markedly,with basaltic rocks ("mafic") dominating oceanic crust,while continental crust consists principally of lower density granitic rocks. Geologists generally agree that the following tectonic plates exist on the earth's surface with roughly definable boundaries.Tectonic plates are sometimes subdivided into three fairly arbitrary categories: major (or primary) plates,minor (or secondary) plates, and micro (or tertiary) plates. Major plates : These plates comprise the bulk of  the continents and the pacific ocean .A major plate is any plate with an area greater than 20 million km. Minor plates : These smaller
