No, it is not. It is tilted in comparison to the Earth's orbit around the Sun. This is why we have different times of seasons in the northern and Southern Hemisphere.

The Earth's orbit around the sun is not a quadratic function, but rather an elliptical path defined by Kepler's laws of planetary motion. To graph it, you would have to use polar coordinates or parametric equations. You can represent the orbit using parametric equations x = acos(t) and y = bsin(t), where 'a' is the semi-major axis, 'b' is the semi-minor axis, and 't' is the parameter representing time.

1. Tilt of earths axis 2. Earths axis remains parallel throughout its yearly orbit.
The season
No; it's about 23 degrees off the plane of its orbit.
The axis of the Earth is tilted 23.5 degress from the plane of the orbit round the sun.
Climate
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
The same way every other place in the world does. Because of the inclination of rotation about the earths axis and the earths orbit around the sun.
There are two things that cause it which are the earths orbit and thetilt of the earths axis.
The same way it affects most of earth. The seasons are caused by the tilt of the earth's axis relative to the plane of its orbit.
Actually, it doesn't. The TILT of the Earth on it axis causes seasonal changes.
The changes in the distance from the sun (due to elliptical orbit) make marginal differences in the amount of energy recieved by the earth,. > The major contributor to seasonal differences is essentially due to the tilt from perpindicular of the earths rotational axis and the fact that the axis will remain parallel throughout the earths yearly orbit around the sun, so in the northern hemisphere the winter equinox is when the top of the axis is at maximum tilt away from the sun, resulting in diffused sunlight and less daylight hours.
