Question

c) How is a horst different from a block mountain​

Answer 1

Horst and graben

• horst and graben refer to regions that lie between normal faults and are either higher or lower than the area beyond the faults.

• A horst represents a block pushed upward relative to the blocks on either side by the faulting, and a graben is a block generally long compared to its width that has been lowered relative to the blocks on either side due to the faulting.

• Horst and graben are formed when normal faults of opposite dip occur in pair with parallel strike lines.

• Horst and graben are always formed together.

• Graben are usually represented by low-lying areas such as rifts and river valleys whereas horsts represent the ridges between or on either side of these valleys.
