If the earth’s tilt on its axis were to increase by 20 degrees, the tropic of Capricorn will be at 23.4° + 20°= 43.4°
If the inclination of the axis of the Earth were to rise, the following changes would occur: In various parts of the planet, both the length of the days and the length of the nights would lengthen or shorten, respectively. The duration of each season as well as its average temperature would be altered. There would be different temperatures in different parts of the planet.
The present angle of the Earth's axis of rotation is 23.5 degrees. Earth's seasons are the result of the planet's axis being tilted. The amount of direct sunlight reaching various latitudes and longitudes on Earth varies throughout the year. When the North Pole is in its most equatorial position, it experiences summer, whereas the South Pole is at its most southern position and so experiences winter. When the South Pole is leaning toward the sun, the situation is reversed.
Some people wrongly believe that summer is when Earth is closest to the Sun, but that is not the case. However, in winter the Northern Hemisphere is physically closer to the Sun than it is in summer. Because of how far away Earth is from the Sun, the planet experiences very small temperature swings when the Sun moves closer or further away.
The Earth's axis of rotation is skewed because of a collision with a massive extraterrestrial object named Theia. The impact jarred the axis out of whack and set in motion the release of material that eventually coalesced as the moon of Earth. Various portions of Earth get direct sunlight at different times because of the tilt's consistent orientation with respect to the Sun.
