Is it true that Earth's history has always had periods of hot and cold weather?
True
The planet Earth is thought to have begun spinning at the moment of its formation, marking the beginning of day and night.
Seasons in climate are caused by variations in the hot-cold temperature range that occur periodically over the orbital period known as a year. Weather is about daily ranges (fluctuations) in temperature, which are dependent on the latitude of the location.

It's true that there have been periods of extreme heat and cold throughout Earth's history; these are known as climate cycles, and they are caused by a variety of factors including variations in the Earth's orbit, volcanic activity, solar radiation, and atmospheric composition.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
