The Fascinating Phenomenon of Solstice: Exploring the Earth's Tilt and the Changing Lengths of Day and Night The Earth's Inclined Axis and the Solstice The Earth's rotation on an inclined axis is a fundamental driver of the changing lengths of day and night throughout the year. This tilt, which is approximately 23.5 degrees, is responsible for the occurrence of the solstice - a remarkable astronomical event that marks the longest and shortest days of the year. The Two Solstices: June and December The solstice occurs twice annually, around June 21st and December 21st. During these events, the sun appears to reach its most northerly or southerly position relative to the Earth's equator. This phenomenon is a result of the Earth's tilted axis, which causes the northern and southern hemispheres to be inclined towards or away from the sun at different times of the year. The June Solstice The June solstice, also known as the summer solstice, marks the longest...
