Answer:

1.- C. Nitrogen

2.- C. Stratosphere

Explanation:

1.- The atmosphere is mostly composed of Nitrogen, which occupies a total of 78%. It is followed by oxygen with 21%, argon with 0.9% and carbon dioxide with 0.03%.

The atmosphere is the part of the earth that contains gas and because of that it becomes the outermost layer with the least density.

The air currents that are in the atmosphere are responsible for regulating temperatures between day and night, to prevent them from being extreme, since they distribute the temperature along the earth's surface.

Nitrogen is very important since it is used by plants to generate amino acids and nutrients, which in turn are then ingested by animals.

2.- The stratosphere is located between the troposphere and the mesosphere, all within the atmosphere in the form of layers. The height at which this layer begins varies by location. In the polar regions it can go between 6 and 9 km and in the equatorial regions between 16 and 20.

Because this layer absorbs the ozone molecules, its temperature increases as it reaches more height. Being the minimum -55 ° and reaching 17 °.

In the lower areas the temperature is normal and stable and has very low humidity.

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.

Zanzabum

Nitrogen and oxygen are the main constituents of the atmosphere plus water vapour near the surface. Carbon dioxide is present in smaller amounts butgl of course it can have a profound influence on the climate as global warming has shown, Greenhouse gases include water vapour, carbon dioxide, methane and nitrous oxide.
