Define and describe Earth Science as a general field with many branches. Identify the field of geology as a branch of Earth Science that deals with the solid part of the Earth. Describe the field of oceanography as a branch of Earth Science that has several subdivisions that deal with the various aspects of the ocean.
Earth science is made of many branches of knowledge concerning all aspects of the Earth system. The main branches are geology, meteorology, climatology, oceanography, and environmental science. Astronomy uses principles understood from Earth to learn about the solar system, galaxy, and universe.

Other fields of research involve greater interdisciplinary interactions. Some of them are listed below. 1. Biogeochemistry: It follows the cycling of elements through the spheres mediated by biological and geological processes, and especially their distribution and fluxes between reservoirs. 2. Mineralogy and Mineral Physics:consider the rock-formi...
Many scientists have begun using an approach known as Earth system science. They treat the entire Earth as a system in its own right, which develops as a result of positive and negative feedbackbetween constituent systems. In the systems approach, scientists combine the use of computer models with global satellite and shipboard data, in attempting ...

Most of all, we look at Earth as a system, examining the cycles and processes—the water cycle, the carbon cycle, ocean circulation, the movement of heat—that interact and influence each other in a complex, dynamic dance across seasons and decades. Why Does NASA Study Earth? NASA's Earth Minute: Why Does NASA Study Earth? Watch on.
We observe our planet’s oceans, land, ice, and atmosphere, and measure how a change in one drives change in others. We develop new ways to observe and study Earth's interconnected systems and we build long-term data records of how our planet evolves. The agency freely shares this unique knowledge and works with institutions around the world.
