Final answer:
The change in seasons on Earth is primarily due to the tilt of Earth's axis, which results in different parts of the Earth receiving sunlight more directly at different times of the year. While Earth's rotation around the Sun and incoming solar radiation are relevant, they are not the primary cause. The Coriolis force does not cause the change in seasons.
Step-by-step explanation:
The reason why planet Earth experiences changes of the seasons is primarily due to D. The tilt of Earth's axis. The familiar cycle of the seasons results from the 23.5º tilt of Earth's axis of rotation. At different times in the year, different parts of the Earth receive the Sun's rays more directly. For example, during the summer solstice, the hemisphere of the Earth that is tilted towards the Sun experiences summer because the Sun's rays strike that part of the Earth more directly, resulting in longer daylight hours and warmer temperatures. Conversely, during the winter solstice, the hemisphere of the Earth that is tilted away from the Sun experiences winter because the Sun's rays are less direct and the daylight hours are shorter, resulting in colder temperatures.
It's essential to note that while the Earth's rotation around the sun and the incoming solar radiation are relevant to the seasons, they are not the primary cause. The Coriolis force, which is more related to weather patterns and ocean currents, does not directly cause the change in seasons either.
