Earth Sphere Communities

Earth is a complex, dynamic system we do not yet fully understand. The Earth system, like the human body, comprises diverse components that interact in complex ways. We need to understand the Earth's atmosphere, biosphere, hydrosphere, and pedosphere as a single connected system. Our planet is changing on all time and space scales. One purpose of The GLOBE Program is to engage students in exploring Earth systems locally, regionally and globally, to contribute to understanding Earth system interactions.

Atmosphere - explore different aspects of our planet’s weather and climate

Biosphere - explore cycles of plant life

Hydrosphere - explore water properties including impacts on animal life (mosquitos and macroinvertebrates)

Pedosphere - explore soil physical and chemical properties

Earth as a System - interactions of spheres
