Exploring the Causes of the Seasons

The video explains the causes of seasonal changes on Earth, focusing on the tilt of the Earth's axis and its orbit around the sun. It describes how the tilt affects the sun's angle in the sky, influencing the intensity of sunlight and resulting in different seasons. The video also compares the sun's position during summer and winter, highlighting the role of sun angle over daylight length in temperature variations.

What primarily causes the change in seasons on Earth?

• The shape of Earth's orbit

• The speed of Earth's rotation

• The tilt of Earth's axis

• The distance of Earth from the sun
