5. The tilting of the earth is deliberately set up

As far as the orbit of the earth is concerned, the earth is tilted at a gradient of 23.5 degrees (you can use a globe as a sample). Without the tilting, there will be no alternating seasons on the earth, the equator will be unbearably hot, the temperate zone will be turned into the Frigid Zone, and Siberia of Russia will be part of the Antarctica. If the tilting is at 90 degrees, the ice and snow in Antarctica will all be melted and the earth will be a complete ocean, with no single stretch of lands. Then can the earth tilt at 24 degrees or 23 degrees?
