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 <u>it becomes the outermost layer with the least density. </u>

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 <u>it is used by plants to generate amino acids and nutrients, which in turn are then ingested by animals.</u>

<u />

2.- The stratosphere is located between the troposphere and the mesosphere, all within the atmosphere <u>in the form of layers</u>. 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.

What describes italy’s mediterranean climate??
Alexus [3.1K]
Hi, according to my research the climate in Italy varies depending on which part of Italy. North of Italy the climate is more unpleasant; with freeing & dry winters, & scorching hot/humid summers. Moving to central Italy climate is more in the middle with not as harsh winters & summers. Also central Itally has a shorter duration for winter but the summers are longer. As for the southern portion of Italy seasons are fair, winter is never bad, & spring and autumn are the same as the summer temperatures in the central regions. Let me know if you need me to explain more. Hope this helped :)

How does the story of the european settlers mimic the biblical story?
wlad13 [49]

Answer:

The story of the European settlers in the USA (if that's what you mean) mimics the biblical story of the Israelites reaching the promised land in that they both believed that if they just came to this place of "milk and honey" they would be able to flourish, and truly enjoy life. This was true for the most part.

kumpel [21]

Answer:

the last picture

Explanation:

The picture that shows the position of Earth during summer in South Carolina would be the last picture, I highlighted it in red below. South Carolina is located in North America. Summer is the hottest time of the year because it is when your location is closest to the sun. Which in the pictures provided the only one in which North America is closest to the sun is the last picture. Also the earth rotates on an inclined axis so pictures 2 and 3 would not be valid.
