<h3>Answer:</h3>

"Mercury"

<h3>Explanation:</h3>

Mercury holds 5.5% specific mass of one Earth (0.055 Earth masses). The facade of Mercury is a little like that of a particular moon. There is no physical characteristic as the planet is too imminent to the sun and is un massive sufficient. It is pitted with billions of cavities, from satellite influences. Since there is no environment, there is no climate to consume the characteristics away over event affected by the influences.

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:
