Geological evidences of ancient glaciation in Jharkhand State of India.
Permo-Carboniferous time, about 300 million years ago, was a period of great glaciation. By Dr. Nitish Priyadarshi Geologist The Earth has a history of climate change. There have been ice ages and super-volcanoes and with them came evolutionary changes in many of the Earth’s inhabitants; A glacial period (or alternatively glacial or glaciation ) is an interval of time (thousands of years) within an ice age that is marked by colder temperatures and glacier advances. There have been five known ice ages in the Earth's history, with the Earth experiencing the Quaternary Ice Age during the present time. Within ice ages, there exist periods of more severe glacial conditions and more temperate referred to as glacial periods and interglacial periods, respectively. The Earth is currently in an interglacial period of the Quaternary Ice Age, with the last glacial period of the Quaternary having ended approximately 10,000 years ago with the start of the Holocene epoch. The Permo-Carboni...
