The history of the Earth can be organized chronologically according to the geologic time scale, which is split into intervals based on stratigraphic analysis. The following five timelines show the geologic time scale to scale.
29 de mar. de 2024 · Learn how Earth evolved from a molten ball to a habitable planet with diverse life forms. Explore the major events and milestones in Earth's history from the Big Bang to the present day with this infographic.
The earliest evidence of life on Earth comes from graphite of biological origin discovered in Greenland that dates 3.7 billion years old. The earliest identifiable fossils have been dated to about 3.5 billion years old and consist of the remains of algal mats composed of bacteria and archaea.
28 de may. de 2024 · Geologic time, the extensive interval of time occupied by the geologic history of Earth. Formal geologic time begins with the Archean Eon (4.0 billion to 2.5 billion years ago) and continues to the present day. Modern geologic time scales also include the Hadean Eon (4.6 billion to 4.0 billion years ago).
22 de mar. de 2012 · This interactive module allows students to explore the science of Earth's deep history, from its formation 4.5 billion years ago to modern times. Additional layers let students explore changes in atmospheric composition, temperature, biodiversity, day length, and solar luminosity over geologic time.
Explore the Earth's history from its formation 4.5 billion years ago to the present day using a 12 hour clock analogy. Learn about the major events and eras of geological time and how they relate to human history.
The geological history of the Earth follows the major geological events in Earth's past based on the geological time scale, a system of chronological measurement based on the study of the planet's rock layers (stratigraphy).
