20. Earth Is Hot Because It Is Close To The Sun
There is a belief that the reason why summers in almost every country in the world is hot is because the Earth is relatively close to the Sun. However, that is not the reason for this. The axis on which the Earth spins is actually tilted to one side and when that part of the axis points towards the Sun, it is summer in that particular hemisphere.
The Earth is sometimes closer and at other times further than the Sun. However, its proximity is only one of the factors influencing the climate.
