Earth and Atmospheric Sciences

- Earth Science
Earth science or geoscience includes all fields of natural science related to the planet Earth. This is a branch of science dealing with the physical, chemical, and biological complex constitutions and synergistic linkages of Earth's four spheres, namely biosphere, hydrosphere, atmosphere, and geosphere. Earth science can be considered to be a branch of planetary science, but with a much older history. Earth science encompasses four main branches of study, the lithosphere, the hydrosphere, the atmosphere, and the biosphere, each of which is further broken down into more specialized fields.
There are both reductionist and holistic approaches to Earth sciences. It is also the study of Earth and its neighbors in space. Some Earth scientists use their knowledge of the planet to locate and develop energy and mineral resources. Others study the impact of human activity on Earth's environment, and design methods to protect the planet. Some use their knowledge about Earth processes such as volcanoes, earthquakes, and hurricanes to plan communities that will not expose people to these dangerous events.
- Atmospheric Science
Atmospheric Science is the study of weather analysis and predictability, climate and global change, the circulation of the atmosphere relating to weather systems and their impact on the Earth, air quality, and other atmospheric processes that affect us. Discovery and understanding in Atmospheric Science is critical to our resiliency, and preparedness so that we may meet the most pressing challenges of our atmosphere-dependent systems.
