The tilt of Earth's axis and its movement around the sun play a crucial role in the changing of seasons in the Northern Hemisphere. Here are the four key points:
1. Tilt of Earth's Axis: The Earth's axis is tilted by about 23.5 degrees relative to its orbit around the sun. This tilt causes different parts of the Earth to receive different amounts of sunlight throughout the year.
2. Movement around the Sun: Earth follows an elliptical orbit around the sun, completing one revolution in approximately 365.25 days. As it orbits, the tilt of the axis remains constant.
3. Solstices: During the summer solstice, which occurs around June 21st in the Northern Hemisphere, the North Pole is tilted towards the sun at its maximum angle. This leads to the longest day of the year in the Northern Hemisphere and the start of summer. Conversely, during the winter solstice, around December 21st, the North Pole is tilted away from the sun at its maximum angle. This results in the shortest day of the year and the beginning of winter in the Northern Hemisphere.
4. Equinoxes: The equinoxes occur around March 21st (spring equinox) and September 22nd (fall equinox) in the Northern Hemisphere. During these times, the tilt of the axis is such that neither the North Pole nor the South Pole is tilted towards or away from the sun. As a result, day and night are of almost equal length all over the world. These represent the transition points between seasons, with the spring equinox marking the beginning of spring and the fall equinox signaling the start of autumn in the Northern Hemisphere.
Overall, the combination of Earth's axial tilt and its movement around the sun leads to the changing seasons in the Northern Hemisphere.
