Answer:

(A) Nebula

Explanation:

The nebula is a cloud of gases such as hydrogen, helium, ionised gases and dust. A nebula is formed when remaining gas from another low mass star or gases in interstellar space condense together then the cloud of gases becomes so dense due to gravity to form the star. There are other types of nebula such as a supernova, which form due to the collapse of the star at the end of its life.

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

  • Thus like the variation of the sunlight in the earth equator and the poles, due to the more bulges to the equator areas and less of above.
  • Similar is the variation in the gases and the density of the mass of the planets and other four-planet are gas giants and have there own atmosphere surrounded in thick layers.
