The document outlines the Earth's subsystems in the context of earth and life science, specifically focusing on four main components: atmosphere, hydrosphere, geosphere/lithosphere, and biosphere. It includes experiments related to the atmosphere, ocean and lake zonations, soil layers, and soil texture analysis. Each subsystem is examined through practical experiments to illustrate their characteristics.
