* Earth sheltering

Earth sheltering is the architectural practice of using earth against building walls for external thermal mass, to reduce heat loss, and to easily maintain a steady indoor air temperature.

Earth sheltering is popular in modern times among advocates of passive solar and sustainable architecture, but has been around for nearly as long as humans have been constructing their own shelter.

* Earth sheltering and positioning buildings to take advantage of natural landforms as windbreaks.

In addition, to decrease costs of operation ( heating, cooling, ...) techniques as Earth sheltering, Trombe walls, ... are often incorporated.

Garibaldi confronts G ' Kar about the lack of support from the Narns, especially in light of the risks the entire Earth crew has taken in helping and sheltering the Narns.

This effect can give rise to a blanket of micrometeorites around the Earth.

The flux of micrometeorites in the neighborhood of the Earth can be estimated by extrapolation from radar and visual meteor data.

In geography, the location of any point on the Earth can be identified using a geographic coordinate system.

1st century BCE ), shows how the distance to the Sun can be computed geometrically, using the different lengths of the noontime shadows observed at three places 1000 li apart and the assumption that the Earth is flat.

Astrobiology addresses the question of whether life exists beyond Earth, and how humans can detect it if it does .< ref name =" about ">

If the large-scale Universe appears isotropic as viewed from Earth, the cosmological principle can be derived from the simpler Copernican principle, which states that there is no preferred ( or special ) observer or vantage point.

Changes can also be caused by natural events such as a large meteor hitting Earth and selective breeding ( artificial selection ) of plants by humans for specific traits.

Carbon generally has low toxicity to almost all life on Earth ; however, to some creatures it can still be toxic – for instance, carbon nanoparticles are a deadly toxins to Drosophila.

It is the heaviest element to occur naturally on Earth ; heavier elements can only be produced by synthesis.

These changes can be caused by processes internal to the Earth, external forces ( e. g. variations in sunlight intensity ) or, more recently, human activities.

Gauss's method involved determining a conic section in space, given one focus ( the Sun ) and the conic's intersection with three given lines ( lines of sight from the Earth, which is itself moving on an ellipse, to the planet ) and given the time it takes the planet to traverse the arcs determined by these lines ( from which the lengths of the arcs can be calculated by Kepler's Second Law ).

Earth personalities tend to be calm, practical, hard-working, brave, smart, wise, stable and patient ; however, they can also be stubborn, possessive, nearsighted and very harsh.

* The Mi-go aliens in the Cthulhu Mythos of H. P. Lovecraft, first appearing in the story " The Whisperer in Darkness " ( 1931 ), can transport humans from Earth to Pluto ( and beyond ) and back again by removing the subject's brain and placing it into a " brain cylinder ", which can be attached to external devices to allow it to see, hear, and speak.

The Earth being spherical, any flat representation generates distortions such that shapes and areas cannot both be conserved simultaneously, and distances can never all be preserved.

Many Earth plants and animals undergo major biochemical changes during their life cycles as a response to changing environmental conditions, for example, by having a spore or hibernation state that can be sustained for years or even millennia between more active life stages.

Earth creatures ( such as animals, plants and even humans ) exposed to Tiberium can either be killed because of the radiation or be transformed into Tiberium-based life-forms, to whom Tiberium radiation is curative rather than toxic.

Michael Rowan-Robinson emphasizes the importance of the Copernican principle: " It is evident that in the post-Copernican era of human history, no well-informed and rational person can imagine that the Earth occupies a unique position in the universe.

Copernicus demonstrated the motion of the planets can be explained without the assumption that Earth is centrally located and stationary.

In cosmology, if one assumes the Copernican principle and observes that the universe appears isotropic from our vantage-point on Earth, then one can prove that the Universe is generally homogeneous ( at any given time ) and is also isotropic about any given point.

Diamonds can also be produced synthetically in a high-pressure high-temperature process which approximately simulates the conditions in the Earth mantle.

Variations in the star's radial velocity — that is, the speed with which it moves towards or away from Earth — can be detected from displacements in the star's spectral lines due to the Doppler effect.

Hence the umbral cone of the Earth can completely envelop the Moon during a lunar eclipse.

A symbolic orbital diagram from the view of the Earth at the center, with the sun and moon projected upon the celestial sphere, showing the Moon's two nodes where eclipses can occur.

It is also possible that some of the dust in the vicinity of the Earth originated from meteoritic impacts upon the moon.

Hipparchus also gave an estimate of the distance of the Sun from the Earth, quoted by Pappus as equal to 490 Earth radii.

With Naram-Sin, Sargon's grandson, this went further than with Sargon, with the king not only being called " Lord of the Four Quarters ( of the Earth )", but also elevated to the ranks of the dingir (= gods ), with his own temple establishment.

In addition, the individual Ph. D. programs in Psychology ( 36th of 240 ), Earth Science ( 17th of 108 ), and Criminology ( 12th ) also earned high rankings.

It is also the apparent magnitude a star would have if it were 32. 6 light years ( 10 parsecs ) away from Earth.

Aberration should also be distinguished from light-time correction, which is due to the motion of the observed object, like a planet, through space during the time taken by its light to reach an observer on Earth.

It is also worth noting that part of the original motivation of the search for stellar parallax was to test the Copernican theory that the Earth revolves around the Sun, but of course the existence of aberration also establishes the truth of that theory.

His research also involved the study of auroral phenomena, which he conducted with his assistant Olof Hiorter, and he was the first to suggest a connection between the aurora borealis and changes in the magnetic field of the Earth.

In fact, the concavity of the water clearly involves gravitational attraction, and by implication the Earth also is a participant.

The brightest star in Capricornus is δ Capricorni, also called Deneb Algedi, with a magnitude of 2. 9, 39 light-years from Earth.

The sun's most southerly position, which is attained at the northern hemisphere's winter solstice, is now called the Tropic of Capricorn, a term which also applies to the line on the Earth at which the sun is directly overhead at noon on that solstice.

New atoms are also naturally produced on Earth as radiogenic daughter isotopes of ongoing radioactive decay processes such as alpha decay, beta decay, spontaneous fission, cluster decay, and other rarer modes of decay.

Chemical elements may also be categorized by their origin on Earth, with the first 98 considered to be naturally occurring, while those with atomic numbers beyond 98 have only been produced artificially as the synthetic products of man-made nuclear reactions.

Aluminum is also far more common in the Earth and Earth's crust than the universe and solar system, but the composition of Earth's mantle ( which has more magnesium and iron in place of aluminum ) more closely mirrors that of the universe, save for the noted loss of volatile elements.

A more speculative, more complex " chip factory " was specified to produce the computer and electronic systems, but the designers also said that it might prove practical to ship the chips from Earth as if they were " vitamins.

The 1997 Rolf de Heer film, Epsilon, also known as Alien Visitor, an alien in female form descends to Earth from Epsilon in the Southern Cross, and inspires an Outback traveler to better his planet.

About 50 million light-years from Earth, M77 is also a Seyfert galaxy and thus a bright object in the radio spectrum.

NGC 246 ( Caldwell 56 ), also called the Cetus Ring, is a planetary nebula with a magnitude of 8. 0, 1600 light-years from Earth.

It is very close to magnitude 6. 1 12 Cam, also 650 light-years from Earth, but the two stars are not a true double star because of their separation.

M94, also classified as NGC 4736, is a face-on spiral galaxy 15 million light-years from Earth.
