Schenk's law is a principle in geology that describes how the movement of tectonic plates affects the formation of mountain ranges. It states that when two tectonic plates collide, the crust can be pushed upward, creating mountains. This process is a key factor in understanding the Earth's geological features. The law is named after Hermann Schenk, a geologist who studied the effects of tectonic activity. Schenk's law helps explain the relationship between plate tectonics and the Earth's topography, providing insight into how natural landscapes are shaped over time.
