If the earths axis were vertical instead of tilted would the temperature in the different regions of the earth differ from one another why?

If the Earth's axis were vertical instead of tilted, there would be minimal seasonal variations in temperature across different regions. This is because the consistent angle of sunlight would result in more uniform heating, causing equatorial regions to remain warm year-round while polar regions would remain cold. Without tilt, the dramatic seasonal shifts experienced in temperate zones would diminish, leading to a more stable climate globally. However, regional differences would still exist due to factors like altitude and ocean currents.
