Geographic characteristics. The north terminus is approximately 70 miles (110 km) west of Springer Mountain, the southern terminus of the Appalachian Trail. Georgia has about 164 miles (260 km) of the trail, and Alabama contains the other 171 miles (280 km) of the 335-mile-long (540 km) trail.
The place where two plates move apart, or diverge, is called a divergent boundary (dy vur junt). Most divergent boundaries occur along the mid-ocean ridges where sea-floor spreading occurs. Divergent Boundaries. Divergent boundaries also occur on land. When a divergent boundary develops on land, two of Earthâs plates slide apart. A deep valley called a rift valley forms along the divergent boundary. For example, the Great Rift Valley in East Africa marks a deep crack in the African continent.
