Respuesta :
1. The Principle of Cross-Cutting Relationships can be used to determine the relative ages of the sedimentary rocks versus canyon formation. Target 1 of 5
2. The sedimentary beds were initially deposited in a(n) horizontal orientation. Target 2 of 5
3. The process of stream incision is younger compared to the folding of the rock units. Target 3 of 5
4. The Principle of Original Horizontality says that folded sedimentary beds have been disturbed since deposition. Target 4 of 5
5. The sedimentary layers are older than both folding and stream incisions.
A canyon is a deep cleft between escarpments or cliffs due to weathering and the erosive activity of a river over geologic time scales. Rivers have a herbal tendency to cut thru underlying surfaces, sooner or later sporting away rock layers as sediments are removed downstream. A river mattress will step by step attain a baseline elevation, which is the same elevation because of the body of water into which the river drains. The techniques of weathering and erosion will form canyons while the river's headwaters and estuary are at significantly specific elevations, especially through areas where softer rock layers are intermingled with harder layers greater resistant to weathering.
A canyon can also refer to a rift between two mountain peaks, which includes the ones in ranges that include the Rocky Mountains, the Alps, the Himalayas, or the Andes. commonly, a river or stream carves out such splits among mountains. maximum canyons have been formed by a system of long-time erosion from a plateau or desk-land degree. The cliffs form due to the fact tougher rock strata which can be proof against erosion and weathering continue to be exposed at the valley partitions.
