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).
Geologic history of Earth, evolution of the continents, oceans, atmosphere, and biosphere; the layers of rock at Earth’s surface contain evidence of the evolutionary processes undergone by these components of the terrestrial environment during the times at which each layer was formed.
The geological history of Earth began 4.567 billion years ago, when the planets of the Solar System were formed out of the solar nebula, a disk-shaped mass of dust and gas left over from the formation of the Sun.
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 . Geologic time scale.
Describe the origins the of the Universe in the context of Big Bang theory. Describe the origins of our solar system in the context of nebular theory. Identify major tectonic and biologic events that occurred in various geologic eons. Based on An Introduction to Geology, Chapter 8: Earth History.
May 28, 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).
One of the major objectives of geology is to establish the history of the Earth from its inception to the present. The most important evidence from which geologic history can be inferred is provided by the geometric relationships of rocks with respect to each other, particularly layered rocks, or strata , the relative ages of which may be ...
What is the Earth made up of and how do we know? What causes the seasons? Are there longer-ranging cycles in Earth's climate?
The main topics studied in Earth history are paleogeography, paleontology, and paleoecology and paleoclimatology—respectively, past landscapes, past organisms, past ecosystems, and past environments. This chapter will cover briefly the origin of the universe and the 4.6 billion year history of Earth.
This chapter will cover briefly the origin of the universe and the 4.6 billion year history of Earth. This Earth history will focus on the major physical and biological events in each eon and Era.
