earth axis

earth axis

earth axis
Any one of a set of mutually perpendicular reference axes established with the upright axis (the z, axis) pointing to the center of the earth. It is used in describing the position or performance of an aircraft or other body in flight. The earth axis may remain fixed or move with that body.

The scientists said their research showed there had been a series of quick advances and retreats of the ice - and this was in keeping with the 20,000 year cycle of the earth axis tilt - otherwise known as a precession cycle.
It requires Rock Smash, Tiger Claw, Earth Axis and Raging Wave.
First method begins with Rock Smash then cancelled with Tiger Claw, cancelled with Earth Axis and cancelled with Raging Wave.
Along with the deviations in the motion of the Moon from the Keplerian orbit and the short-period nutation of the Earth axis, the evection mechanism is detected in spectral zenith observations of the atmosphere at Novolazarevskaya station (Antarctica).
The major solar disturbances cause deviation from the Keplerian orbit of the Moon motion and, at the same time, deviations in the Earth axis in the short-period nutation (31.8 and 14.8 days), provide periodic gravitational influence on the Earth-Moon system.
The increased distance, he said, reduces just seven per cent of the Sun's heat on earth, but the earth axis bring summer season to the northern hemisphere at this time of the year.
Instead of axis tilt, terms such as axis difference, equator plane, earth axis, orbit slant are used.
Instead of tilt; slante (eyik), pitched (eyimli), side (yan) (grammatical mistakes) Instead of ecliptic: Epiclic Instead of axis tilt; axis difference, Equator plate, Earth axis, orbit slope Instead of geoids: Ellipse Instead of northern hemisphere, north pole Instead of 30[degrees]-60[degrees] latitudes for central zone: between the parallels of 27[degrees]-66[degrees]
Washington, March 3 (ANI): NASA has announced that the February 27 Chile earthquake was so powerful that it likely shifted an Earth axis and shortened the length of a day.
In the GSC system, detectors rotate about the Earth axis, moving along a motionless parallel given by [phi] = const.
Sidereal day, [T.sub.ST], is the period of rotation of the Earth and the detectors in the GSC system about the Earth axis. In particular, in the GSC, at the moment (t + [T.sub.ST]), the detector A returns to the same location, where it was at time t.
It is necessary to note that the points of the Earth space, which are on the Earth axis, move forward only.
