Which crust sinks deeper into the mantle?
ocean crust
What formations develop after faulting breaks the crust into blocks and a block slips downward relative to the surrounding blocks?
Subduction of oceanic lithosphere at convergent plate boundaries also builds mountain ranges. When tensional stresses pull crust apart, it breaks into blocks that slide up and drop down along normal faults. The result is alternating mountains and valleys, known as a basin-and-range.
What type of mountains are commonly located where continents have collided?
Fold mountains are often associated with continental crust. They are created at convergent plate boundaries, sometimes called continental collision zones or compression zones. Convergent plate boundaries are sites of collisions, where tectonic plates crash into each other.
What are the largest groups of mountains on Earth called?

| 2 | Southern Great Escarpment | 5,000 km (3,100 mi) |
| 3 | Rocky Mountains | 4,800 km (3,000 mi) |

What is the deadliest mountain?
Annapurna
Why is the Hillary Step so dangerous?
With increasing numbers of people climbing the mountain, the Step frequently became a bottleneck, with climbers forced to wait significant amounts of time for their turn on the ropes, leading to problems in getting climbers efficiently up and down the mountain.
How long are you in the death zone on Everest?
Mount Everest is the highest place on Earth. It rises an unbelievable 29,035 feet (8850 m) above sea level. It’s so high that if you were standing at sea level and could transport yourself instantly to the top of the mountain, you would pass out and probably be dead within 30 minutes.
