Answer:
Step-by-step explanation:
Volcanic eruptions release molten rock or lava that can form new rock on the earth's surface. The gases,dust, and ashes that erupt from a volcano also affect the climate by covering the earth's surface; therefore, creating a cooling effect on the location of the volcano. Also, in the past where there were super volcanic eruptions that it caused global warming due to volcanoes also releasing greenhouse gases.
This is a relatively simple half life calculation.
To go from 6 to 3 grams, 1622 years is required.
3 to 1.5 grams another 1622 years is required.
So, it undergoes exactly 2 half-lives or 3,244 years.

Answer:
C. The mean is 111.9F and the median is 114.5F.
Step-by-step explanation:
The mean is 111.9 given that (105 + 113 + 122 + 121 + 116 + 118 + 107 + 93)/8 = 111.875 which can be rounded to 111.9 F.
Organizing the values we have:
[93, 105, 107, 113, 116, 118, 121, 122]
We find that the median is going to be between 113 and 116. Therefore:
(113 + 116) / 2 = 114,5
Therefore, the correct answer is option C.
