If the earth's axis were perpendicular to the plane of its orbit, the earth would still have winter and summer as the two main seasons. The two seasons would beÊoccurringÊdaily since the earth would still be rotating but on a perpendicular plane to its orbit.Ê
This titled position of the earths axis is known as inclination of the earths axis. The earth's rotation axis makes an angle of about 66.5 degrees with the plane of its orbit around the sun, or about 23.5 degrees from the perpendicular to the ecliptic plane.
we might just have only one season and its axis will be tilted towards the sun for throughout the year
The axis of the Earth's rotation isn't perpendicular to the plane of its orbit around the Sun. As a result, the northern hemisphere (for example) is tilted toward the Sun in June but tilted away from the Sun in December.
Due to the part of orbit the Earth is on.
The earth's orbit around the sun is almost circular. The slight deviation from circularity plays no practical part in the climate. Weather and climate are to do with the tilt of the earth's axis, and it's orientation to the plane of the orbit - if the axis was perpendicular to the plane of the orbit there would be no seasons cycle. If the orbit were farther from the sun, it would be colder (eg Mars), or closer, it would be hotter (eg Venus), although in both those examples there are other factors contributing (eg atmospheric density).

The tilt of the Earth's axis in relation to the plane of its orbit.
Stoped rotating. A day would take a year. Perpendicular. There would be no seasons.
Not really. The seasons arise due to 1) the movement of the earth around the sun, and 2) the fact that the axis of rotation of the earth is not perpendicular to earth's plane of orbit about the sun.
No, the tilt of the axis away from the perpendicular is the main cause.
If the Earth had no axial tilt, there would be no seasons. Weather would probably be pretty boring.
It doesn't. It is the tilting of the Earth's axis that creates the seasons. The orbit of the Moon (and our orbit around the Sun) affects Earth's tides.
No. Earth's orbit is NOT tilted. Earth orbits the Sun in the same plane as the rest of the planets. What IS tilted is Earth's axis of spin (as compared to the plane of its orbit), It is this tilt of this axis that causes the seasons as Earth makes its annual orbit of the Sun.
The Earth's seasons are a result of the way the Earth is titled on an axis and its elliptical orbit around the sun. The Earth is the only planet to have seasons.

Pretty much fixed (pointing at the north star), so it's tilted from the perpendicular to its orbit by about 23 degrees. (Thus the seasons.)
No, the Earth's axis of rotation is at a twenty three and a half degree angle to the plane of its orbit, which is closer to being perpendicular than it is to being parallel. This 23.5 degree "axial tilt" are responsible for, among other things, our seasons.
