How was the Bryce Canyon influence by a process internal to the Earth?

Question

 Describe at least one way that the Bryce Canyon has been or could be influenced/shaped/changed by a process internal to the earth - formation of igneous rocks, volcanoes, earthquakes, are all examples.

Answer 1

Bryce Canyon was influenced by several internal Earth processes, one of which is uplift. Two main periods of uplift eroded multiple formations that had been created. The Laramide orogeny impacted the western area of modern-day North America from 70 Ma to 50 Ma. This occurrence closed the Cretaceous Seaway by contributing to the buildup of the Rocky Mountains. The geologic event also helped form the Kaiparowits, Wahweap, and Straight Cliffs.

Around 16 Ma, an episode of uplift caused separations within the Colorado Plateaus; each plateau had a different uplift rate and was segmented by faults. Vertical joints were created, each with its own rate of erosion. Within the Claron Formation, the relatively erosion-resistant White Cliffs formed into monoliths, while the softer Pink Cliffs were eroded into hoodoos, or lone pinnacles within badlands. Other features created were windows, walls, natural bridges, and arches.
