Sentences with phrase «axial tilt with»

I don't have the information right at hand but isn't it understood that in the early holocene the earth was on a slightly different axial tilt with the north pole pointed slightly more toward the sun?

When the cranial base and the caudal part of the skull are shortened the circular model brain becomes increasing ellipsoid and there is greater axial tilt with an increase in height rostrally (white arrow).

Not exact matches

First, variations in the shape of the earth's orbit (more versus less elliptical), the axial tilt, and the direction of that tilt with respect to perhelion all combine to affect the relative seasonal insolation for the northern and southern hemispheres.

With enough time, you have an ice age, checked only by the fact that the ice can only get so far south, because this all hinges on seasonal insolation changes resulting from the axial tilt of the earth, and this makes no difference at or near the equator — insolation there is constant, regardless of the tilt of the earth, and the days are warm and long enough to hold back any threat of snow and ice.

The Pleistocene ice ages seem to correlate with periodicities in the Earth's orbital eccentricity, axial tilt, and precession.

For example the axial tilt could make the landmasses point more to the sun and the ionising process controlled by GCR would be more efficient since more of them would hit the large oceans; vice versa would both reduce the impact of variations in GCR and reduce the cooling associated with a particular amount of incoming GCR.

According to this theory, changes in the shape of Earth's orbit around the sun (eccentricity), variations in Earth's axial tilt (obliquity), and the tendency for Earth to «wobble» with respect to the direction of its rotational axis (precession) affect climate.

Palaeoclimate studies show that differences in the manner in which the Earth orbited the Sun during the Last Interglacial are sufficient to explain the higher temperatures over most parts of the Northern Hemisphere, particularly due to greater axial tilt and eccentricity compared with the present day orbital configuration.

For crying out loud the gravitional mass of Jupiter makes small changes in the eccentricy of the earth's and depending on whether eccentricity max / min is in or out of phase with earth axial tilt min / max spells the difference between glaciers a mile thick covering everything north of Washington, DC and whether grass is able to sprout in Montreal.

These ice sheets expanded and contracted in a regular rhythm, with each glacial maximum separated from adjacent ones by 41,000 years (based on the cycle of axial tilt).

The Earth's orbit grows slowly more and less elliptical, even as the angle of the planet's axial tilt, and the wobble of the poles as the planet spins (much like what you see with a spinning top), also change slightly over thousands of years.
