Is it true that Earth's history has always had periods of hot and cold weather?

Answer 1

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.
