The of drama geology is all around you. Have you ever been to Yellowstone National Park? If so, you have stood on a catastrophe in the making. The central region of the park is inside a collapsed volcanic crater that pulses with the hidden energy of magma deep below that will eventually explode in an eruption surpassing any in recorded history. Or have you ever driven in the rolling hills of the Piedmont region that extends from New Jersey to Alabama? Then you have crossed the core of an ancient mountain range that once rivaled the Himalayas. Now almost completely eroded away, these peaks were created 300 million years ago in the collision of tectonic plates that formed the supercontinent of Pangaea. Or have you ever noticed something as simple as tipped fence posts or leaning retaining walls? If so, then you have witnessed one of the most powerful and irresistible agents of geologic change, the ubiquitous force of gradual erosion called mass wasting.

A Science That Is Intuitive, Accessible, Concrete, and Exciting

Wherever you live or travel, geology is everywhere. Wouldn't you like to know how to read the rocks and landscape; how to make sense of debates over natural resources; and how to appreciate the "deep time" that governs a geologist's sweeping perspective?

These 36 half-hour lectures are your initiation into the geological world that lies just outside your door. The Nature of Earth: An Introduction to Geology introduces you to physical geology, the study of Earth's minerals, rocks, soils, and the processes that operate on them through time.

No other science deals more practically with the world on which we live, telling us where to dig a well; when to add lime to soil; how gold, oil, and other valuable minerals are formed and where to find them; what kinds of structures are safest in an earthquake zone; and why some active volcanoes are deadlier than others
