Earth Science
The American Geological Institute (AGI) is a nonprofit federation of 45 geoscientific and professional ociations that represents more than 120,000 geologists, geophysicists, and other earth scientists.
Founded in 1948, AGI provides information services to geoscientists, serves as a voice of shared interests in our profession, plays a major role in strengthening geoscience education, and strives to increase public awareness of the vital role the geosciences play in society’s use of resources, resilience to natural hazards, and the health of the environment.

Earth science (also known as geoscience, the geosciences or the Earth sciences), is an all-embracing term for the sciences related to the planet Earth. It is arguably a special case in planetary science, the Earth being the only known life-bearing planet. There are both reductionist and holistic approaches to Earth science.
There are four major disciplines in earth sciences, namely geography, geology, geophysics and geodesy. These major disciplines use physics, chemistry, biology, chronology and mathematics to build a quantitative understanding of the principal areas or spheres of the Earth system.
The following fields of science are generally categorized within the geosciences:
- Geology describes the rocky parts of the Earth’s crust (or lithosphere) and its historic development. Major subdisciplines are mineralogy and petrology, geochemistry, geomorphology, paleontology, stratigraphy, structural geology, engineering geology and sedimentology.
- Geophysics and Geodesy investigate the figure of the Earth, its reaction to forces and its magnetic and gravity fields. Geophysicists explore the Earth’s core and mantle as well as the tectonic and seismic activity of the lithosphere.
- Soil science covers the outermost layer of the Earth’s crust that is subject to soil formation processes (or pedosphere). Major subdisciplines include edaphology and pedology.
- Oceanography and hydrology (includes limnology) describe the marine and freshwater domains of the watery parts of the Earth (or hydrosphere). Major subdisciplines include hydrogeology and physical, chemical, and biological oceanography.
- Glaciology covers the icy parts of the Earth (or cryosphere).
- Atmospheric sciences cover the gaseous parts of the Earth (or atmosphere) between the surface and the exosphere (about 1000 km). Major subdisciplines are meteorology, climatology, atmospheric chemistry and atmospheric physics.
- A very important linking sphere is the biosphere, the study of which is biology. The biosphere consists of all forms of life, from single-celled organisms to pine trees to people. The interactions of Earth’s other spheres – lithosphere/geosphere, hydrosphere, atmosphere and/or cryosphere and pedosphere – create the conditions that can support life.

It’s Bill Nye the Science Guy! In this episode, Bill explores the science of electricity. Itâs a flow of electrons (amperage) and requires a potential difference (voltage), just as the flow of water requires differences in pressure.
This is an excerpt of a lecture given by Alexei V. Filippenko, Professor of Astronomy, for his class at UC Berkeley called “How Stars Shine: Cosmic Furnaces” (”Introduction General Astronomy”):
Could you really destroy the Vatican using a small amount of antimatter made in the Large Hadron Collider? Thats the question Carnegie Mellons Manfred Paulini seeks to answer in the lecture Angels and Demons: The Science Revealed. Dr. Paulini, an experimental particle physicist and member of the CMS experiment at CERNs Large Hadron Collider, discusses the science facts and fiction in the movie Angels and Demons, based on Dan Browns best-selling novel.
