An El Niño event changes the wind and water currents over the Pacific Ocean. The trade winds usually blow from east to west around the equator. ... The warm, western water makes for humid air and thus rainfall at that end of the ocean. During an El Niño event, this pattern breaks down.

Answer:

"Island ArcsIsland arcs are long, curved chains of oceanic islands associated with seismic activity and mountain-building processes at certain plate boundaries. They occur where oceanic tectonic plates collide. Along one side of these island arcs, there is usually a long, narrow deep-sea trench.At island arcs, the denser plate is subducted and is forced into the partially molten mantle under the less dense plate. The islands are composed of the extrusive igneous rocks basalt and andesite. The basalt originates most likely from the plastic mantle. The andesite originates most likely from the melting of parts of the descending plate and sediments that had accumulated on its surface.Which list identifies minerals present in andesite from the greatest percentage by volume to the least percentage by volume? "
As the different situations and events gave rise to the seven different tectonic plates which comprises the over all structure of the planet, as there are a number of geological sites that took there shape because of the movement of the different planetary regions, layers, or the components which makes up the deep down trenches and the islands along with the different volcanic hotspots.
Mostly the subduction region is only due the movement or the sliding of the different tectonic plates which gives rise to a way different catastrophic events like the creation of the seismic way may generate the earth quakes inside the different regions.
Along, with that the different climates across the globe are also due the difference in such geological sites.

Where did the original atmospheric oxygen come from

faust18 [17]

The correct answer is - cyanobacteria.

The atmospheric oxygen came from the cyanobacteria. These were one of the earliest living organisms on Earth. The cyanobacteria was using photosynthesis in order to create its own food. The photosynthesis process requires sunlight, carbon dioxide, water, and oxygen. The oxygen is mostly released as a waste product from the process of photosynthesis, thus the cyanobacteria were literally releasing oxygen that was ending up into the atmosphere. As more and more cyanobacteria there were across the planet, more and more oxygen they were releasing into the atmosphere, slowly changing the composition of the atmosphere, and setting the basis of it as we know it now.
