murzikaleks [220]

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.

Which flowchart best explains how a change in ocean temperature, such as

slavikrds [6]

Answer:

D. Ocean - Atmosphere - Wind - Weather

Explanation:

The El Nino (warm) and La Nina (cool) are the opposing phases of climatic patterns in the tropical pacific ocean and take place every 3 to 7 years. Combined they are called ENSO.

First, in the El Nino ocean temperatures in the eastern tropical pacific ocean rise above average and this leads to rainfall over Indonesia and storms in central pacific. This rising air increases the air motion and leads to dryness and high surface pressure during the La Nina phase this condition gets reversed.

During the El Nino, the northwestern pacific tends to be warmers and the southern tier of California tends to be cooler and wetter. These surface temperatures are caused and changed by the help of trade winds. These blows from east to west along the pacific ocean.

These phenomena thus influenced the weather along the western and the eastern pacific ocean.
