Question

BlackTom AI · Accepted Answer

The question asks: The seasons on the Earth is due to:

Option a: The tides of the ocean. This is not related to why seasons occur. Tides are caused by gravitational forces from the Moon and Sun on Earth's oceans, not by the tilt of the axis or orbital geometry that creates seasonal patterns.

Option b: The size of the earth. The Earth's size is essentially constant and does not drive seasonal changes. Seasons arise from variations in sunlight with orbital position and axial tilt, not from how large the planet is.

Option c: The inclination of the spinning axis with the rotation plane about the sun. This is the key factor that produces seasons. The tilt causes different hemispheres to receive varying amounts of sunlight throughout the year, leading to seasonal changes as the Earth orbits the Sun. The angle changes the intensity and duration of sunlight on different latitudes during different times of year.

Option d: The position of the Earth in Solar system. While the Earth’s orbital position relative to the Sun affects insolation throughout the year, the seasons are primarily caused by the axial tilt, not merely by where Earth happens to be in its orbit relative to other planets. The orbital shape (nearly circular) and distance changes do influence seasonal magnitude somewhat, but the dominant cause is axis tilt.

In summary, the pivotal concept is that the axial tilt relative to the orbital plane shifts the distribution of sunlight across the globe over the year, creating seasonal patterns. The other options do not capture this mechanism and are either unrelated (tides, size) or only partially descriptive (orbital position) but not the primary cause.
