Weathering and Erosion Weathering causes rocks to disintegrate through physical breaking or chemical dissolution. Weathered rock material is then subject to erosion – the process of separating the weathered material from its source. Words that are often used to describe the process of erosion

What Happens When a Dam Breaks?
On May 19, 2020 the Edenville Dam in Edenville, MI failed. Fortunately no lives were lost, but 10,000 people were displaced or evacuated, more than 2,000 homes were damaged or destroyed, and tens to hundreds of millions of dollars in damages occurred. This dam failure released floodwaters
How do Rivers Work?
Geomorphology Geomorphology is the study of Earth’s surface and the processes that sculpt it. To understand how these processes operate, geomorphologists (scientists who study geomorphology) often use physical models. Physical models are a compact and simplified way of representing a
