The major environmental concerns in Oceania and Australia re the overfishing and the invasive species.
Explanation:
Australia and Oceania, as pretty much every place in the world, have some big environmental problems. Unlike the rest of the world, this region doesn't really have problem with deforestation, but it has big problems with overfishing, as well as with invasive species. The overfishing and the invasive species combined, manage to create huge problems, especially when it comes to the protection of the native species and keeping their numbers stable.
The overfishing has occurred because of the higher demand for fish. It is not just the local population that uses the fish extensively in its diet, but also there is huge demand worldwide, so lot of fish is actually for export. This has resulted in badly damaging the fish populations, and bringing some species on the verge of existence. The invasive species, have been brought in order to solve some problems, especially when it comes to food supply for the humans, but it turned out that they are fatal toward the local flora and fauna. Species like the cat, fox, camel, pigs, have managed to outcompete the indigenous fauna and lead to its endangering.

The oldest rocks will be found at the Mariana Trench.
Explanation:
There is a general rule when it comes to where the oldest rock of a plate is located and where the youngest rock is located. That is based on where there are divergent boundaries and where there are convergent boundaries. The places where there are divergent boundaries are the places where new crust is formed, thus the closest a place is to the boundary the younger the rock is. The places where there are convergent boundaries are the places that are the furthest away from the places where the new rock is formed, so they are where the oldest ones are.
In this case, we have the Pacific plate. The East Pacific Rise is a place where new crust forms, meaning that the youngest crust is there. The oldest crust will be located in the trenches that are the furthest away from it, and that would be the Mariana Trench, which is also the deepest trench in the world.
Other trenches of the Pacific that would be among the candidates for some of the oldest rocks are:
- Kuril Trench
- Japan Trench
- Kermadec-Tonga Trench

Answer:
En antropología cultural, la difusión transcultural es un concepto introducido por Leo Frobenius en su obra Der westafrikanische Kulturkreis (1897/98), que se refiere a la expansión del uso de objetos, ideas, estilos , religiones, tecnología, lenguas, etc. entre personas de diferentes culturas. Es un proceso diferente de la difusión de innovaciones dentro de una cultura específica, ya que la difusión transcultural siempre involucra a más de una cultura. El fenómeno puede darse por adopción voluntaria, por imitación, o por imposición cultural.
Difusión cultural de Egipto, Grafton Elliot Smith (1929).
La difusión a través de diferentes culturas es un fenómeno bien testimoniado y, por tanto, que no es cuestionado. Por ejemplo la práctica de la agricultura parece haberse expandido desde algún lugar de Medio Oriente a toda Eurasia, hace menos de 10 mil años, habiendo sido adoptadas las prácticas agrícolas por muchas culturas diferentes. Otros ejemplos bien establecidos de difusión, incluyen el empleo de carro de guerra, el trabajo del hierro en tiempos prehistóricos o el uso del automóvil o la indumentaria occidental de negocios, durante el siglo XX.
