Aug 21, 2019 · A history-of-Earth timeline includes everything from the birth of the sun and solar system to present-day earthquakes in California. Changes over the past 4.6 billion years were usually slow and incremental, but also sometimes violent and …

The history of Earth is divided into four great eons, starting 4,540 mya with the formation of the planet. Each eon saw the most significant changes in Earth's composition, climate and life. Each eon is subsequently divided into eras, which in turn are divided into periods, which are further divided into epochs.

This time represents Earth’s earliest history, during which the planet was characterized by a partially molten surface, volcanism, and asteroid impacts. Several mechanisms made the newly forming Earth incredibly hot: gravitational compression , radioactive decay, and asteroid impacts.

Scientists have ever-improving tools to understand how Earth’s internal processes shape the planet’s surface, how life can be sustained over billions of years, and how geological, biological, atmospheric, and oceanic processes interact to produce climate—and climatic change.

Sep 22, 2024 · The main topics studied in Earth history are paleogeography, paleontology, and paleoecology and paleoclimatology—respectively, past landscapes, past organisms, past ecosystems, and past climates. The changes that have occurred since the inception of Earth are vast and significant.

This article assembles some of the key events. From evolution to extinction, these are events that have unfolded as part of the Earth timeline. Though opinions vary, we’ve leaped through 4.5 billion years of Earth’s history and provided a general guideline.

Resources in this section pertain to the formation and evolution of the Earth and how it has been discovered through the relative and absolute dating of rocks and fossils. Topics include rock layer sequencing, fossil correlation, and radiometric dating.
