Answer:
Step-by-step explanation:
The most predictable effect of such a cosmic catastrophe, where Earth's axis becomes perpendicular to the line between the sun and Earth, would be the loss of seasons as we currently experience them.
Earth's tilt is responsible for the variation in seasons throughout the year. When the axis is tilted, different parts of the planet receive varying amounts of sunlight as Earth orbits the sun. This tilt causes the changes in temperature and weather patterns that define the four seasons.
If the axis were suddenly perpendicular to the line between the sun and Earth, the planet would no longer experience this tilting effect. As a result, there would be a significant reduction or even the absence of seasonal variations.
Regions near the equator would likely experience relatively consistent temperatures and weather conditions throughout the year, with minimal variations. However, regions closer to the poles, which currently experience more extreme seasonal differences, would be most affected.
These polar regions would experience more drastic changes. Instead of having alternating seasons of summer and winter, they would likely have a continuous period of daylight or darkness, depending on their position relative to the sun. The length of these periods would depend on the Earth's specific axial alignment.
Overall, the loss of Earth's tilt would lead to a significant disruption in the global climate and the disappearance of familiar seasonal patterns, resulting in substantial changes in weather, ecosystems, and agricultural patterns worldwide.
