Exploring Earth's Seasons and Their Causes

The video explains why Earth experiences seasons, debunking the theory that distance from the sun is the cause. Instead, it highlights Earth's axial tilt as the primary reason. The tilt causes variations in sunlight angle and energy distribution, leading to different seasons. The video also discusses how daylight duration changes with Earth's tilt.

What is a common but incorrect belief about the cause of Earth's seasons?

• Earth's distance from the Sun

• Ocean currents

• The Sun's movement across the sky

• Earth's magnetic field
