Explanation:

Block Mountains

Block mountains also known as Horst. It is formed when the tensional forces causes the plates on

the earth crusts to move apart. This movement causes the rocks to be stretched. Temperatures are low and the rocks are brittle. Instead of folding, they break into large blocks.

Due to the compressional forces, the middle section of the rocks are uplifted, resulting it to be higher than the surrounding land.An example of the block mountain is the Vosges in France and the Black Forest in Germany which are separated by the Rhine Valley. These block mountains are formed from the divergence of the Eurasian Plate and the North American plate.

Rift valleys are long, narrow depressions on the earth surface bounded by more or less parallel faults. A rift valley is also known as a graben. Rift valleys are thought to have been developed either from the action of tensional forces in the crust or from the action of compressional forces.

Scientists sometimes argue whether both block mountains (horsts) and rift valleys (grabens) move, or if only one part moves. Many feel that the rift valley (graben) is the part that moves, due to the force of gravity. The block mountain (horst) is left standing higher above the sunken graben. This is difficult to determine.

Many fault-block mountain ranges are a horst and graben system. In these systems, the mountains (horsts) are separated by deep valleys (grabens). Sometimes the valleys are actually wide basins.
