Grade Level: 5th Grade
Earth is comprised of four interconnected systems: geosphere, hydrosphere, atmosphere, and biosphere. All of Earth’s processes are due to energy and matter cycling within and among these four systems. Because these systems are so connected, it is important to understand both individual characteristics of each system independently as well as features of their interactions with each other.
