Question

What would happen if the tilt of the Earth was more than $45$ degrees ?

Answer 1

Hint: In order to write the answer to this question, we will be looking up for the effects of the exposure of our planet earth to the sun and the climatic effects due to it.

Complete answer:
As we all know that the earth does not rotate exactly perpendicular to the axis, but it rotates on its own axis making an angle of $23.5$ degrees. We also know that whether it is the climatic change, the seasons and even the day-night cycle is governed by the rotation of the earth and its exposure towards the sun.

Knowing all the facts, we can interpret that seasons would be much more pronounced and the poles would be colder overall if the Earth's axis was tilted $45$ degrees instead of the present $23.5$ degrees. The seasons are controlled by the Earth's axis, which is at just the right angle to the sun to sustain complex life.

Also, a $45$-degree axial tilt will focus more heat on the hemisphere facing the sun. Over the summer, more solar radiation will reach the temperate zones and poles, as well as the equator. During the winter, the same will happen, with temperatures near the poles becoming much colder.

The day-night cycle will be disrupted as well. Much of the earth will be perpetually on the day side during the summer months of a given hemisphere, similar to how there are bands at the poles that receive $24$ hours of sunlight or nightfall depending on the season.

Because of the more dramatic changes in temperature, which allows the forced movement of hot air to places where cooler air remains, the Earth will undergo more extreme weather patterns. Hurricanes, tornadoes, thunderstorms, and flooding will be more intense and devastating. As a result, a $45$-degree tilt of the Earth's axis will make life much less likely to prosper.

Note: It is very important to note that the present angle at which the earth is aligned is best suitable to sustain life. If the angle is increased to $45$ degrees or even more than that, it will be very difficult to sustain life on earth due to the above mentioned drastic effects.
