North American rift system

The North American Rift System is a major geological feature where Earth's crust is slowly pulling apart within North America. This process creates a zone of thinning and faulting, leading to the formation of valleys, basins, and volcanic activity. It is part of larger tectonic forces that shape the continent’s landscape over millions of years. The system influences seismic activity and can result in the development of rift valleys or deep depressions, contributing to the continent’s geological diversity. Essentially, it’s an area where the Earth's crust is expanding, causing land to stretch and fracture gradually.
