Rapid Erosion

Meanwhile, in the waiting room, Papaia and Ravioli are talking about a book Banani found, on the geological evidence of Noah’s flood.

Papaia: We said the book gives four examples. What’s the first?

Ravioli: The layers beneath the Tapeats Sandstone were rapidly eroded and then broadly scraped flat.

Papaia: First rapidly eroded, and then flattened? Two distinct processes!

Ravioli: Yep… and we know this erosion happened on a large scale because we can see its effects from one end of the Grand Canyon to the other.

Papaia: So, not a local phenomenon?

Ravioli: Exactly! This massive erosion affected many different underlying rock layers—granites and metamorphic rocks, and tilted sedimentary layers.

Papaia: But how do we prove it was large-scale erosion?

Ravioli: There are two pieces of evidence that this large-scale erosion was rapid. First, we see no signs of weathering beneath the boundary.

Papaia: If there had been weathering, we’d expect to find soil layers.

Ravioli: But there aren’t any.

Papaia: Second, we find boulders and formations known as “storm beds” in the Tapeats Sandstone above the boundary.

Ravioli: It says here that storm beds are sand layers with unique internal features produced only by storms, like hurricanes.

He points at a paragraph.

Papaia: Boulders and storm beds don’t deposit slowly.

Igor: Did someone say “storm”? Like the one that’s about to hit… when your evaluation lands on the boss’s desk! 🤣
