Sentences with phrase «spin axis tilt»

Regardless of the carbon source (s), it has been shown that the hyperthermals were astronomically paced, spurred by coincident maxima in the Earth's orbit eccentricity and spin axis tilt [17], which increased high - latitude insolation and warming.

Climate oscillations evident in Fig. 4 of Hansen et al. [52] were instigated by perturbations of Earth's orbit and spin axis tilt relative to the orbital plane, which alter the geographical and seasonal distribution of sunlight on Earth [58].

Not exact matches

From those extremely limited data, they have still been able to tease out Earth's 24 - hour rotational rate and the tilt of its spin axis.

Not only does the axis precess (every 51,000 years), but the proximity of Jupiter offers a strong gravitational forcing function that modifies the eccentricity of its orbit and the obliquity (tilt) of the spin axis.

For the next year the Gravity Probe B team, led by Francis Everitt of Stanford, will monitor the spheres to see if the warp or drag of space tilts their spin axes out of alignment.

«There must have been regional climate and chemical conditions that varied in time and space,» he says, adding that this would occur as the tilt of Mars's spin axis changed over tens of thousands of years, a wobble caused by the lack of a massive moon to stabilise the planet.

Using a model he developed, Hamilton found that the initial location of Sputnik Planitia could be explained by Pluto's unusual climate and its spin axis, which is tilted by 120 degrees.

There can be irregularities, of course, such as the odd spin axis of Uranus, which for as - yet - unexplained reasons is nearly tilted on its side, and Pluto's odd orbit, which occasionally takes it inside the path of Neptune.

Uranus» tilt essentially has the planet orbiting the sun on its side, the axis of its spin is nearly pointing at the sun.

During its January 2008 flyby, NASA's MESSENGER spacecraft detected an internal magnetic field consistent with the field from a dipole nearly aligned with the planet's spin axis (with a dipole tilt around 10 °).

Uranus» spin axis is «tilted» 97.77 °.

«We got a good ball of mud spinning with the right tilt of axis, I'm very happy we have this opportunity to keep peopling it.»

The gravity of the Moon and (to a lesser extent) of the Sun makes the Earth's axis swivel around like a tilted spinning top.

This is the same as the cycle of obliquity, the tilt angle of the earth's spin axis relative to its orbit.

For the record, the reason is that Earth's spin axis is slightly tilted.

The slowly changing orbit and tilt of the spin axis affect the seasonal distribution of insolation [27], and thus the growth and decay of ice sheets, as proposed by Milankovitch [28].

These climate oscillations have dominant periodicities, ranging from about 20 to 400 kyr, that coincide with variations in the Earth's orbital elements [26], specifically the tilt of the Earth's spin axis, the eccentricity of the orbit and the time of year when the Earth is closest to the Sun.

Glacial — interglacial oscillations of the CO2 amount and ice sheet size are both slow climate feedbacks, because glacial — interglacial climate oscillations largely are instigated by insolation changes as the Earth's orbit and tilt of its spin axis change, with the climate change then amplified by a nearly coincident change of the CO2 amount and the surface albedo.
