Question

which of the following statements best describes the difference between folded mountains and fault - block mountains?
folded mountains form when stress causes pieces of earths crust to be thrust upward to higher elevations, whereas fault - block mountains form when segments of earths crust are bent and doubled over.
folded mountains form when segments of earths crust are bent and doubled over, whereas fault - block mountains form when stress causes pieces of earths crust to be thrust upward to higher elevations.
folded mountains form only at convergent plate boundaries, whereas fault - block mountains form only at divergent plate boundaries.
folded mountains form only at divergent plate boundaries, whereas fault - block mountains form only at convergent plate boundaries.

Explanation:

Folded mountains form when segments of Earth's crust are bent and doubled over due to compressional forces (like at convergent plate boundaries). Fault - block mountains form when stress causes pieces of Earth's crust to be thrust upward (due to tensional forces, often at divergent or transform - like settings in some cases).

Answer:

Folded mountains form when segments of Earth's crust are bent and doubled over, whereas fault - block mountains form when stress causes pieces of Earth's crust to be thrust upward to higher elevations.
