The Moon's orbital plane is slowly slowing the Earth's axal rotation down, as well as the Earth's is slowing the moon's axal rotation down. Eventually both axal rotations will stop completely, and they will orbit in synchronization until they are eventually burnt up by The Sun. as the Earth's axis slows down it will extend the days and nights by many hours, and the thermocline will be the same as the moons; scorched during the day, and frozen at night.
The ecliptic crosses the celestial equator at the two equinoxes.
Chromosomes are aligned along with the equator of the cell in metaphase.
It's because the Earth's axis is tilted. Therefore the plane of the equator is tilted (at about 23.5 degrees) away from the plane of the Earth's orbit. Therefore the celestial equator is tilted away from the ecliptic.
No effect at all. However the plane of the equator will be tilted to the same amount as the Earth as compared to the plane in which the Earth orbits the Sun. This plane is called "the ecliptic".
Because the equator is tilted with respect to the ecliptic plane.
The ecliptic crosses the celestial equator at the two equinoxes.
Chromosomes are aligned along with the equator of the cell in metaphase.
The equator makes an angle of roughly 23.5 degrees with the ecliptic plane.
It's because the Earth's axis is tilted. Therefore the plane of the equator is tilted (at about 23.5 degrees) away from the plane of the Earth's orbit. Therefore the celestial equator is tilted away from the ecliptic.

Those would be the "equinoxes".
This is difficult to describe in text, without sketches, but I'll try: -- First, the 'equator' of the sky: That's a line all around the sky that's exactly over the Earth's equator. In your sky, wherever you are, this 'celestial' equator is a semi-circle from the exactly-east point on your horizon to the exactly-west point. Its highest point is due south of you, and at that point, its height above your southern horizon is (90 degrees minus your latitude). If you're on the equator, then the celestial equator passes right over your head. If you're at the north pole, then the celestial equator coincides with your horizon. If you're in Minneapolis, Salem OR, Bangor, Grenoble, Torino, or Belgrade, at 45° north latitude, then it passes 45° above your south horizon. -- The highest of the 3 stars in Orion's belt is on the celestial equator. -- The ecliptic is another line all the way around the sky. It crosses the celestial equator at two places, and it's tilted 231/2 degrees to the equator. So half of the ecliptic is above (north) of the equator, and the other half of it is below the sky's equator. -- Through the day, as the Earth turns, one of the two points where the ecliptic crosses the equator will be in your sky at any one time. The ecliptic will appear high in your sky for half of the day, and low in the sky for the other half. The point where it crosses directly south of you will wiggle up and down through a total of 47 degrees in 24 hours. -- The left pincher of Scorpius and the heart of Leo (Regulus) are on the ecliptic. The eye of Taurus (Aldeberan) is not too far off of it. The ecliptic is actually the line where the plane of Earth's orbit cuts through the 'bowl' of the sky. Some of the results are: -- The sun is always on the ecliptic. -- The planets are always close to the ecliptic. Now, in mid-2013, Jupiter is smack on it. -- The moon is always within about 51/2 degrees of the ecliptic. -- In Summer, the sun is high, so the ecliptic ... with the moon and planets ... is low during the night. -- In Winter, the sun is low, so the ecliptic ... with the moon and planets ... is high during the night. Remember those two points where the ecliptic crosses the celestial equator ? Those points in the sky are the 'equinoxes'. Those points are where the sun is on March 21 and September 21.
The analemma would stretch in the north-south dimension.
The equator line
Neptune. Neptune is tipped sideways to the ecliptic.
No effect at all. However the plane of the equator will be tilted to the same amount as the Earth as compared to the plane in which the Earth orbits the Sun. This plane is called "the ecliptic".
That's the "ecliptic". It's an imaginary circular line in the sky that's inclined 23.5 degrees to the Celestial Equator, and intersects the CE at the equinoxes. The constellations along the line are the constellations of the Zodiac.
