Endogenic and Exogenic Forces
Endogenic Forces Endogenic forces a can be classified as slow movements (diastrophic) and sudden movements. Slow movements cause changes very gradually which might not be visible during a human lifetime. Exogenic Forces The forces which derive their strength from the earth’s exterior or originate within the...
