Browsing: Ice Age
An Ice Age is a prolonged period of reduction in the temperature of the Earth’s surface and atmosphere, resulting in the presence or expansion of continental and polar ice sheets and alpine glaciers. Earth has experienced at least five major ice ages over the course of its history, with the most recent one being the Quaternary Ice Age, which began about 2.6 million years ago and continues today. During these periods, ice covers significant parts of the continents, leading to dramatic changes in the climate and significantly affecting the planet’s environment and life forms. These changes have influenced the evolution and geographic distribution of many species and have had substantial impacts on the planet’s climate systems and geography through processes like glaciation and deglaciation.
