Sentences with phrase «axial tilt»

Axial tilt refers to the angle at which a planet's axis is tilted relative to its orbit around the Sun. It is responsible for the change in seasons on Earth. Full definition
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).
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?
Seasons are actually caused by Earth's 23.4 - degree axial tilt.
These Milankovitch cycles are tied to Earth's wobbly orbital axis, its oscillating axial tilt, and its orbital eccentricity.
We know that Mars was once a lot wetter than it is now, and we know it was also covered in glaciers that have come and gone as the Martian climate has radically changed, driven by drastic periodic changes in the planet's axial tilt over the eons.
Build on a shallow concept to deepen it (e.g., «Demonstrate and explain how the Earth's axial tilt causes the seasons»);
Only axial tilt applies, and the Holocene Optimum was whole planet.
Unlike Earth or Mars, Venus has a very low axial tilt — just 2.64 ° relative to the ecliptic.
This greater axial tilt provided stronger insolation (solar heating) at high latitudes and weaker insolation at low latitudes.
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.
Here's how it begins: Days may be dark right now — after all, as the memes proclaim, axial tilt is the reason for the season.
Axial tilt is the reason for the season after all.
Axial tilt is an astronomical term regarding the inclination angle of a planet's rotational axis in relation to a perpendicular to its orbital plane.
The axial tilt may equivalently be expressed in terms of the planet's orbital plane and a plane perpendicular to its axis.
In our solar system, the Earth's orbital plane is known as the ecliptic, and so the Earth's axial tilt is officially called the obliquity of the ecliptic.
The axial tilt is expressed as the angle made by the planet's axis and a line drawn through the planet's center perpendicular to the orbital plane.
It also alters the planet's axial tilt: The North Pole had been steadily wandering toward Canada, but researchers recently realized that the current ice melt has jolted it on a new course toward the United Kingdom, at an accelerated rate of 7 inches a year since 2000.
Axial tilt: Earth tilts toward the Sun at an angle that changes from an approximate 22 - degree tilt to a 24.5 - degree tilt over a period of 41,000 years.
That ancient cataclysm might have been lucky for us, as the moon helps to stabilise the axial tilt of Earth, removing one source of extreme climate change that might otherwise have afflicted our planet.
Though temperatures can reach a blistering 400 °C at the equator, the planet's axial tilt is nearly zero, so parts of the poles never see sunlight.
The axial tilt of Uranus is 98 °, so effectively the planet is now spinning in a direction opposite to its orbital motion around the sun.
Its axial tilt is nearly zero, though, raising the possibility that craters at the poles might never see sunlight and so could harbour ice.
Axial tilt: The Earth tilts toward the Sun at an angle that changes from an approximate 22 - degree tilt to a 24.5 - degree tilt over a period of 41,000 years.
Jupiter's axial tilt is very small, so its seasonal variation is minimal; Uranus, on the other hand, has an axial tilt so extreme it is virtually on its side, which means that its hemispheres are either perpetually in sunlight or perpetually in darkness around the time of its solstices.
Planets also have varying degrees of axial tilt; they lie at an angle to the plane of the sun's equator.
Factors such as the sizes of the planet and the star, continental distribution, ocean depth, the amount of water present, tectonic activity, variability of the surface temperature, atmospheric composition, the magnetic shield, speed of rotation, axial tilt, eccentricity of the orbit, the type and amount of radiation received, the age of the solar system, and the possibility of panspermia within the system are all considered.
Investigate the axial tilts and the presence or absence of seasons on other planets.
Can you predict which planets have seasons, based on their axial tilts?
On December 1, 2009, two astronomers submitted a pre-print suggesting that the planet's extreme axial tilt (an obliquity of 97 degrees) may have resulted from the presence of a large moon that has since been ejected from orbit around the ice giant by the pull of another planet during the orbital migration of the giant planets early in the formation of the Solar System.
I'll mention that although orbital variation (precession) causes opposite insolation changes in the two hemispheres, axial tilt (obliquity) variation causes synchronous insolation changes in the two hemispheres.
However, the Jurassic is basically irrelevant to the modern climate because * everything * was different then (for a very abbreviated list: solar intensity, atmospheric composition, locations of continents, oceans, and climatic zones, axial tilt, orbital dynamics, photosynthetic species).
The axial tilt, as explained by Steel could explain why the south pole is so cold right now and the north pole is warm.
Apsidal precession, combined with all the other odd and not so odd peregrinations of the orbit, axial tilt, magnetic poles, core and mantle fluid dynamics, continents bobbing around all over the place and so on, make my head hurt!
