Why Can't It Always Be Summer?

Summer’s enchanting allure is explained by Earth's tilt, not its distance from the Sun. Seasons occur because of Earth’s 23.5-degree tilt, causing different parts of the world to receive varying sunlight throughout the year. Experts define summer based on meteorological and astronomical parameters, where daylight plays a pivotal role.

Richmond Richmond, Sep 22 (The Conversation) – The allure of summer, with its long days by the water, is undeniably enchanting. Yet, this season of magic, as author Jenny Han puts it, must eventually give way to autumn.

Amanda, a 5-year-old from Chile, wonders why summer can't last forever. The simple answer lies in Earth's 23.5-degree tilt, a result of a colossal impact billions of years ago, causing the planet to always lean in the same direction.

This tilt is responsible for the varying seasons. During June, the Northern Hemisphere tilts toward the Sun, resulting in longer days and warmer temperatures. Conversely, the Southern Hemisphere leans away, facing winter. Throughout the year, Earth's position changes, bringing different sunlight levels to various regions, thus defining the seasons.
