B.
the angle between sunlight and the earth's surface


C.
the pull of the moon on the earth


D.
the speed of rotation of earth on its axis

Answer 1

Answer:

Earth has seasons because our planet's axis of rotation is tilted at an angle of 23.5 degrees relative to our orbital plane – the plane of Earth's orbit around the sun. The tilt in the axis of the Earth is called its obliquity by scientists.

Answer 2

The speed of rotation of earth on its axis is the key to the earth has seasons.

The correct option is D.

What are seasons on earth?

Seasons are the changes in the temperature of the earth from time to time.

There are five seasons are there in Earth.

The season change on Earth depends on the rotation of Earth on its axis.

The Earth is tilted 23 and a half degrees in its axis, this is called obliquity.

It is summer in that hemisphere when the earth's axis points towards the sun.

Winter is predicted when the earth's axis points away from the sun.

Thus, the correct option is D. the speed of rotation of the earth on its axis.
