Explanation: The Great Pacific Patch Garbage is difficult to be cleaned up because it is a very large area that contains debris that reaches the marine ecosystem.
It is located at the north central of the pacific ocean. The collection of the debris is primarily from the countries like Asia, Hawaii, California and extends to many other places too.
The pelagic area is characterized by high concentration of plastic, chemical sludge. Removing this will remove plankton present in pelagic zone.
Mineral crystals that form when magma cools slowly are larger than crystals that form when lava cools rapidly. Minerals form when rocks are heated enough that atoms of different elements can move around and join into different molecules.
