Further away from the equator, they'd get more pronounced. A bigger area would never get night during summer, and never day during winter.
In that case, the seasons would be more pronounced.
no more hunting seasons
Earth's axis has a tilt of 23.5 degrees; this is what causes seasons. 0 degrees: practically no seasons (there would be minor changes due to a varying distance from the Sun). 45 degrees: seasons would be much more pronounced.
The Earth would start to heat up and the ocean would evaporate.
In that case, the seasons would be more pronounced.
The planet gets warmer.
They would be more extreme: winters would be colder and summers would be hotter. The temperate zones would contract, and the polar and tropical zones would expand.
The day lengths will alway be the same, 12 hours of day and 12 hours of night for nearly everywhere on earth except for the extreme poles. For a given position on earth, the sun will always more or less follow the same path in the sky. There would be no seasons, for a given location, the earth would receive the same amount of sun each day (ignoring cloud cover).
If the Earth had a 0 degree tilt, there would be no seasons, and the weather would be more uniform across all latitudes. With a 12 degree tilt, the seasons would be more pronounced, resulting in more extreme weather patterns and temperature variations between summer and winter.
it means earthquakes will happen more often
If Earth's axis were not tilted, there would be no seasons as we know them. The tilt of Earth's axis is what causes different parts of the planet to receive more direct sunlight at different times of the year, creating the four seasons. Without this tilt, the amount of sunlight reaching each area of the Earth would remain constant throughout the year, leading to a more consistent climate globally.
If the Earth were tilted at 40 degrees, the seasons would be more extreme in the regions closer to the poles. This would result in longer and colder winters, and hotter summers. The equatorial regions might experience less variation in temperature throughout the year.
