Earth History

Earth History refers to the study of the planet Earth through geological and paleontological timescales, focusing on the formation and development of the Earth, its atmosphere, oceans, and the life forms that have existed over billions of years. This field encompasses the analysis of rock formations, fossils, and geological processes to understand significant events such as the formation of continents, climate changes, mass extinctions, and the evolution of life. Earth History maps out the chronological sequence of events from Earth’s origin approximately 4.5 billion years ago to the present, examining how physical, biological, and chemical processes have shaped the planet. It informs our understanding of current environmental issues and the ongoing changes occurring within the Earth’s systems.
