2. MOUNTAINS
THE COLLECTION OF PROCESSES THAT PRODUCE A MOUNTAIN BELT IS CALLED OROGENESIS.
MOUNTAINS ARE CLASSIFIED BY THE DOMINANT PROCESS THAT FORMED THEM

3. FOLDED MOUNTAINS
MOUNTAINS THAT ARE FORMED PRIMARILY BY FOLDING ARE CALLED FOLDED MOUNTAINS.
COMPRESSIONAL STRESSES ARE THE MAJOR FORCE THAT FORMS FOLDED MOUNTAINS.
EX. THE APPALACHIAN MOUNTAINS

4. FAULT-BLOCK MOUNTAINS
LARGE-SCALE NORMAL FAULTS ARE ASSOCIATED WITH STRUCTURES CALLED FAULT-BLOCK MOUNTAINS.
THESE MOUNTAINS FORM AS LARGE BLOCKS OF CRUST ARE UPLIFTED AND TILTED ALONG NORMAL FAULTS.
EX. SIERRA NEVADA

5. GRABEN
NORMAL FAULTING OCCURS WHERE TENSIONAL STRESSES CAUSE THE CRUST TO BE STRECTCHED OR EXTENDED.
AS THE CRUST IS STRETCHED, A BLOCK CALLED A GRABEN, WHICH IS BOUNDED BY NORMAL FAULTS, DROPS DOWN.

6. HORSTS
GRABENS PRODUCE AN ELONGATED VALLEY BORDERED BY RELATIVELY UPLIFED STRUCTURES CALLED HORSTS.

7. DOMES
THE BLACK HILLS OF WESTERN SOUTH DAKOTA FORM A LARGE DOMED STRUCUTRE THOUGHT TO BE FORMED BY UPWARPING.
WHEN UPWARPING PRODUCES A CIRCULAR OR ELONGATE STRUCTURE, THE FEATURE IS CALLED A DOME.

8. BASINS
DOWNWARPED STRUCTURES HAVING A CIRCULAR SHAPE ARE CALLED BASINS.
