What would happen if Earth's axis were perpendicular to its orbit, meaning it had no tilt? A Seasons would last six months ( Seasons would not exist (C) Temperatures would rise overall (D) It would be summer year-round

If Earth's axis were perpendicular to its orbit, meaning it had no tilt, the correct answer would be: **(B) Seasons would not exist.** Here's why: 1. **Seasons and Axial Tilt**: The seasons on Earth are primarily caused by the tilt of the Earth's axis (approximately 23.5 degrees) relative to its orbit around the Sun. This tilt causes different parts of the Earth to receive varying amounts of sunlight throughout the year, leading to the changing seasons. 2. **Perpendicular Axis**: If the axis were perpendicular to the plane of its orbit, every location on Earth would receive roughly the same amount of sunlight throughout the year. This means there would be no significant variation in temperature or daylight hours that characterize the seasons. 3. **Temperature Effects**: While temperatures might not rise overall, the lack of seasons would lead to a more uniform climate across the planet, rather than the distinct seasonal changes we currently experience. In summary, with no axial tilt, there would be no seasons as we know them, and the climate would be more stable and consistent throughout the year.
