A long interval of geologic time passes(1.3 billion years), throughout which the elves chasm gneiss likely remained deeply buried in the crust d. The Colorado plateau( including the Grand Canyon region) is uplifted by the plate tectonics processes e. The profiling of the elves chasm gneiss is metamorphosed into the gneiss and subjected to intense pressure and heat for millions of years deep in the crust as a result of plate- tectonic processes f. The Colorado river and it’s tributaries carve the modern Grand Canyon system into the uplifted Colorado plateau: including black rain canyon, inside which the grinds and sandstone and the unconformity between them become exposed g. Both the sedimentary rock layers and the elves chasm gneiss, plus the uncomformity between them, remained hurried in the crust for another interval of geological time, approximately 519 million years h. The sand and gravel layers are themselves buried under successive layers of younger sediments,gradually becoming deeply buried enough that they are compacted and cemented together, forming a sedimentary rock i. The profiling (original in metamorphosed source rock) for the elves chasm gneiss is formed

Answer 1

The events creating the exposure at Blacktail Canyon begin with the formation of the elves chasm gneiss, its subsequent burial and metamorphosis, the deposition of sediment layers, their compaction into sedimentary rock, the uplift and erosion exposing the gneiss, the uplift of the Colorado plateau, and finally the carving of the canyon system by the Colorado river.

Step-by-step explanation:

The sequence of events that created the exposure at Blacktail Canyon can be arranged chronologically as follows:

1. The profiling (original in metamorphosed source rock) for the elves chasm gneiss is formed.
2. The profiling of the elves chasm gneiss is metamorphosed into the gneiss and subjected to intense pressure and heat for millions of years deep in the crust as a result of plate- tectonic processes.
3. A long interval of geologic time passes(1.3 billion years), throughout which the elves chasm gneiss likely remained deeply buried in the crust.
5. Water flows across the exposed elves chasm gneiss, cutting into the surface and depositing layers of sand and gravel atop it.
7. The sand and gravel layers are themselves buried under successive layers of younger sediments, gradually becoming deeply buried enough that they are compacted and cemented together, forming a sedimentary rock.
9. Both the sedimentary rock layers and the elves chasm gneiss, plus the uncomformity between them, remained hurried in the crust for another interval of geological time, approximately 519 million years.
11. The block of the crust containing the elves chasm gheiss is gradually uplifted and the rocks overlying it are eroded off, until the gneiss is exposed at the surface.
13. The Colorado plateau(including the Grand Canyon region) is uplifted by the plate tectonics processes.
14. The Colorado river and it’s tributaries carve the modern Grand Canyon system into the uplifted Colorado plateau: including black rain canyon, inside which the grinds and sandstone and the unconformity between them become exposed.
