Earth's Dynamic Systems

There are two major pathways for the flow of energy and matter on Earth: (1) the hydrologic system—the circulation of water over Earth's surface and through its atmosphere powered by energy from the Sun, and (2) the tectonic system—the movement of material powered by heat from Earth's interior. These two unifying themes form the backbone of Earth's Dynamic Systems, providing a logical, well-crafted, spectacularly illustrated introduction to physical geology.
