If the East pacific rise is the source of new rock, which trench would contain the oldest
AnnyKZ [126]

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

Explanation: When plants within the Marshes die,rather than decompose through Microbial activities and release their Carbon into the atmospheres,the carbon remain buried within the muddy soil and due to the impact of the waves Microbial activities are slowed and in most cases prevented,As the ocean waves finds its path through the mashes more matters are deposited on the buried plants locking the carbon and preventing the release of carbon.

This is one of the main importance of the wetlands like mashes on climate change.

Which feature is considered evidence for continental drift?
UkoKoshka [18]
Plate tectonic is a scientific theory that says the Earth’s lithosphere is divided into several plates. The plates glide over the mantle. In early 20th century, this theoretical model builds on the concept of continental drift. It was first proposed by the scientist Alfred Wegener in 1912. After seafloor spreading was validated, the theory was accepted by the geoscientific community.
