The Earth experiences different seasons throughout the year due to its tilt on its axis and its orbit around the sun. The four seasons - spring, summer, autumn, and winter - bring changes in weather, daylight, and natural surroundings.
The Earth's axis is tilted at an angle of about 23.5 degrees relative to its orbit around the sun. This tilt causes different parts of the Earth to receive varying amounts of sunlight at different times of the year, leading to the changes in seasons.
Spring occurs when the Earth's axis is tilted neither toward nor away from the sun. This results in more balanced lengths of day and night. In the Northern Hemisphere, spring begins around March 20th, while in the Southern Hemisphere, it begins around September 23rd.
Summer happens when the Earth's axis is tilted toward the sun, causing longer days and shorter nights. In the Northern Hemisphere, summer begins around June 21st, and in the Southern Hemisphere, it begins around December 21st.
Autumn occurs as the Earth's axis starts to tilt away from the sun, resulting in shorter days and longer nights. In the Northern Hemisphere, autumn begins around September 22nd, and in the Southern Hemisphere, it begins around March 21st.
Winter takes place when the Earth's axis is tilted away from the sun, leading to the shortest days and longest nights. In the Northern Hemisphere, winter begins around December 21st, while in the Southern Hemisphere, it begins around June 21st.
Here are some key points to remember about the seasons:
Understanding the seasons helps us appreciate the changes in weather and nature throughout the year.
