The Earth and the moon move in predictable ways and have predictable effects on each other as they orbit the sun.
This video explains the Earth's rotation and revolution and how this movement causes night and day and how Earth's tilt gives us seasons.
This video demonstrates how the Earth's tilt and revolution around the sun changes the angle
This video demonstrates how the Earth's tilt and revolution around the sun changes the angle at which sunlight hits the Earth's surface creating the different seasons.
