Credits Mission statement For the purposes of what I hope to be a technically and scientifically accurate document, I will define our goal thus:
By Early Modern Englishmany nouns were capitalized, and the earth became and often remained the Earth, particularly when referenced along with other heavenly bodies. More recently, the name is sometimes simply given as Earth, by analogy with the names of the other planets.
Oxford spelling recognizes the lowercase form as the most common, with the capitalized form an acceptable variant. Another convention capitalizes "Earth" when appearing as a name e. It almost always appears in lowercase in colloquial expressions such as "what on earth are you doing?
The bodies in the Solar System formed and evolved with the Sun. In theory, a solar nebula partitions a volume out of a molecular cloud by gravitational collapse, which begins to spin and flatten into a circumstellar diskand then the planets grow out of that disk with the Sun.
A nebula contains gas, ice grains, and dust including primordial nuclides. Geological history Hoodoos at the Bryce Canyon National ParkUtah Earth's atmosphere and oceans were formed by volcanic activity and outgassing.
Water vapor from these sources condensed into the oceans, augmented by water and ice from asteroids, protoplanetsand comets. The two models  that explain land mass propose either a steady growth to the present-day forms  or, more likely, a rapid growth  early in Earth history  followed by a long-term steady continental area.
Over the period of hundreds of millions of years, the supercontinents have assembled and broken apart.The Sun is now in the quietest phase of its year activity cycle, the solar minimum - in fact, it has been unusually quiet this year - with over days so far with no observed sunspots.
Hyperspace – A Scientific Odyssey A look at the higher dimensions. Do higher dimensions exist?
Are there unseen worlds just beyond our reach, beyond the normal laws of physics? The generally accepted age for the Earth and the rest of the solar system is about billion years (plus or minus about 1%). This value is derived from several.
What is PhET? Founded in by Nobel Laureate Carl Wieman, the PhET Interactive Simulations project at the University of Colorado Boulder creates free interactive math and science simulations.
Earth’s magnetic field is a field of electric current that is conducted from the earth’s solid inner core through the liquid outer core (Richard). The electrical current goes around the earth and through it at the north and south poles.
The table below presents an abbreviated geologic time scale, with times and events germane to this essay. Please refer to a complete geologic time scale when this one seems inadequate.
