Earth's Rotation, Revolution, and Seasons Explained

  • The Earth rotates on its axis, creating day and night, with the side facing the Sun experiencing day and the opposite side experiencing night. Simultaneously, the Earth revolves around the Sun, completing one orbit in 365 days, leading to the concept of revolution.
  • The Earth's axis is tilted, causing different parts of the planet to receive varying amounts of sunlight and heat, resulting in the creation of seasons. The tilt leads to the northern and southern hemispheres leaning towards or away from the Sun at different times, influencing the weather patterns.
  • To understand the Earth's rotation and revolution, a demonstration using a globe and a table lamp can be conducted. The globe represents the Earth, while the lamp symbolizes the Sun. By spinning the globe and moving it in a circular motion around the lamp, the concept of day and night, as well as the Earth's revolution, can be visually comprehended.
