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.

nata0808 [166]

Answer:

1. Applying <u>the principle of original horizontality</u> -indicates that layers were repositioned from a flat-lying orientation.

2. Magma intrudes into layers of sedimentary rock and displaces them. We can deduce that the intruded magma that crystallizes is younger than the surrounding sedimentary layers by applying <u>the principle of crosscutting relationships</u>.

3. While visiting the Grand Canyon, you are amazed by the depth of layers of sedimentary rock before you, <u>the law of superposition</u>-- is evident here where progressively younger layers have formed over time and are stacked upon each other.

4. A fault cuts through layers of limestone, sandstone, and conglomerate. The surrounding layers must be <u>older</u> than the fault.

5. A mass of granite has inclusions of surrounding sandstone. The sandstone and surrounding layers show evidence of uplift over time. The granite must be <u>younger</u> than the sand deposits.

andrey2020 [161]

To date, the majority of neandertal fossils have been found in Europe and western Asia.

There may have been little direct contact between neanderthals and modern humans over thousands of years. They might have contributed to the Neanderthals' impending extinction by preventing them from going back to the areas they liked best.

Around 40,000 years ago, all traces of Neanderthals vanished. The most recent Neanderthal fossils have been found at a few isolated locations in western Europe and the Near East, which was probably the last known location for this early human species.
