Australia and Arizona rock layers (lemmy.world)

Does Arizona and Australia share the same rock formation layers? I was watching a TV show and a lot of the Australian landscaped looked very red and similar to Sedona Arizona. Do they share the same layers?

No, they're not even close. However, similar processes exist everywhere and this results in a similar appearance. It's called "Uniformitarian" -- "the present is the key to the past"

The theoretical system Lyell presented in 1830 was composed of three requirements or principles: 1) the Uniformity Principle which states that past geological events must be explained by the same causes now in operation; 2) the Uniformity of Rate Principle which states that geological laws operate with the same force as at present; 3) the Steady-state Principle which states that the earth does not undergo any directional change. The three principles form a single thesis called “uniformitarianism” [...]

But it also means that the same processes can be active in multiple places independently at the same time.
