Earth is made up of five major parts or subsystems: the Atmosphere, Hydrosphere, Biosphere, Cryosphere, and Geosphere. Each major part is connected to the other parts in a complex web of processes.

The Earth System Satellite Images help students observe and analyze global Earth and environmental data, understand the relationship among different environmental variables, and explore how the data change seasonally and over longer timescales.  

The Earth can be considered a system of interrelated parts. Learn about Earth Systems Science and the spheres that make up the Earth System. Find out why NASA studies the Earth system.

Our Earth is a dynamic system with diverse subsystems that interact in complex ways. Questions that scientists have about the Earth as a System may include the following. As you learn more about the Earth System, reflect on these questions. 

Earth is a system of systems.

A system is an organized group of related components that work together to carry out functions that the individual parts cannot do alone.  The Earth System, like the human body system, are similar in that they comprise diverse parts that interact in complex ways.

The My NASA Data visualization tool, Earth System Data Explorer (ESDE), helps learners visualize complex Earth System data sets over space and time. Visit this page to review the datasets we have available to you and their organization by Earth System sphere, science variable, dataset name, and start/end dates.
