What would change/happen if Earth was not tilted on its axis by 23.5 degrees and instead had zero tilt on its axis
The Correct Answer and Explanation is:
If Earth had zero tilt on its axis, several important changes would occur that would drastically alter life on the planet. The most significant difference would be the absence of seasons. Currently, Earth’s 23.5-degree axial tilt causes different parts of the planet to receive varying amounts of sunlight throughout the year, leading to seasonal changes.
Without this tilt, every location on Earth would receive the same amount of sunlight every day of the year. This means there would be no winter, spring, summer, or autumn. Instead, each region would have a consistent climate based only on its distance from the equator. The equator would remain hot all year round, while the poles would stay cold and frozen with minimal temperature variation.
The length of day and night would also remain constant throughout the year. Currently, the tilt causes longer days in summer and shorter days in winter for each hemisphere. With no tilt, every place on Earth would experience exactly twelve hours of daylight and twelve hours of darkness every day.
These changes would have significant effects on ecosystems, agriculture, and human lifestyles. Many plants and animals have adapted to seasonal changes. Without seasons, migratory patterns of birds, breeding cycles of animals, and plant growth schedules would be disrupted. In agriculture, crops that rely on specific seasonal temperatures and daylight patterns would either not grow or require artificial environments.
Cultural and social traditions based on seasons would also disappear. Festivals, holidays, and activities tied to spring, summer, fall, and winter would no longer have meaning or purpose.
In summary, without the 23.5-degree axial tilt, Earth would become a planet with no seasons, constant daylight hours, and a more static climate. This would deeply affect ecosystems, agriculture, and human culture across the globe
