The circle of latitude is wherein all positions of the Earth's axis are parallel to each other. It is an imaginary east-west circle connecting all locations.
The earths rotational axis is tipped 23.5 degrees from vertical The earths rotational axis remains parallel throughout its orbit of the sun, so at one point in the yearly orbit the top half of the axis is at maximum tilt away from the sun, this is the winter solstice / shortest day (northern hemisphere) and summer solstice / longest day (southern hemisphere) Half a year later the positions are reversed as the axis remains parallel leaving the top of the axis tilting in.
The axis is what the Earth rotates around, like the axis on a wheel.
The geographical North and South Pole - not the magnetic poles.
Parallelism of AxisThe earth is constantly rotating as it revolves about the sun. It rotates on an imaginary axis. The earth's axis always points in one direction. Thus as the earth revolves about the sun, the position of the axis at any one time is always parallel to the position it occupied at any previous time. This phenomenon is called parallelism of axis.It always points to the pole star.
Because it tilts on its axis
It is a circle drawn around the globe parallel to the equator and at right angles to the meridians.

1. Tilt of earths axis 2. Earths axis remains parallel throughout its yearly orbit.
The earths rotational axis is tipped 23.5 degrees from vertical The earths rotational axis remains parallel throughout its orbit of the sun, so at one point in the yearly orbit the top half of the axis is at maximum tilt away from the sun, this is the winter solstice / shortest day (northern hemisphere) and summer solstice / longest day (southern hemisphere) Half a year later the positions are reversed as the axis remains parallel leaving the top of the axis tilting in.
It is false, due to precession of the equinoxes, but true enough to apply to short-term analysis.
No; it's about 23 degrees off the plane of its orbit.
The earths rotation about its axis has no affect on the orbit of satellites about earth. Only their relative velocities and positions are relevant, not their orientation
Its the orientation of the earths rotational axis that defines the equinox, the axis remains parallel throughout the orbit of the sun, and when its side on to the sun (spring and autumn), thats the equinox (equal length of day and night).
because of the earths axis
The earths rotational axis is tilted approx. 23 degrees from vertical The earths rotational axis remains parallel throughout its rotation around the sun, high summer (longest day) in the northern hemisphere, is when the top of the axis is at full tilt toward the sun. (shortest day in the southern hemisphere)
Because Earths axis is tilted.
