What are the features of the North Pacific Ocean basin described in terms of seafloor spreading?
Formation of new crust along the Middle-Ocean ridge and subduction along the North America plate.
The East Pacific Rise is a chain of submarine volcanoes and faults that separates the Pacific tectonic plate on its west from the Cocos plate, Nazca plate and Antarctica plate on its east.
It is characterized by variable rate of ocean floor spreading which reach 15cm/year nearby Easter Island. This is the fasted rate of separation observed in the world.
The Cocos and Nazca plates are pushed below the North and South America plates. This is the source of magma and energy for the chain of volcanoes that runs along the west coast of North America (Cascade Range) and South Amerca (Andes).
The Pacific Rise hosts a series of geothermal vents emitting supe-heated fluids (up to 400 Celisius) that are called "Black smokers" from the color of the emissions enriched in dark sulfurs. A whole biological community is evolved feeding on these emissions thanks to the presence of bacteria able to convert the minerals in organic matter through chemosynthesis (equivalent to what plants do through photosynthesis).

The North Pacific Ocean basin features include a network of mid-ocean ridges characterized by seafloor spreading, resulting in the formation of new oceanic crust. This process leads to the creation of oceanic trenches, such as the Mariana Trench, where older crust is subducted beneath tectonic plates. The basin also exhibits a complex system of fracture zones, transform faults, and volcanic activity associated with the movement of tectonic plates.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
