If there were only 100 people on the Earth,how much money would you earn,the language that would be popular and the percent of w
VikaD [51]
The questions about language and religion depend a lot on where the 100 people are (assuming all of them are in the same place). In terms of money, 25 people would be really rich, 50 people would be middle income, and 25 people would be really poor( I'd probably be a middle income person). The specific amount of money would depend on the time period. Since there are only 100 people, at least 90% of them would have the same religion. Also, the chances of war and conflict are really low, because everyone would know each other.(Sorry my answer is so long)

Katarina [22]
<span>There are lots of countries that do not have volcanoes, some of them include: 
South Africa, Nigeria, Zimbabwe, Malawi, Djibouti, Somalia, Algeria, Morocco, Tunisia, Liberia, Denmark, Norway, Wales, Finland, Sweden, Ireland...

These countries, as well as the rest that lack volcanoes are all countries that are not lying above collision or submersion lines between the tectonic plates, nor have a hot spot beneath them, which is where the volcanoes appear. The best known is the 'Ring of Fire' in the Pacific, where most of the active volcanoes are.</span>

13. A soil contains 30% smectite, 10% kaolinite, and 2% organic matter. Calculate an estimated CEC for this hypothetical soil.
marta [7]

Answer:

estimated CEC for given hypothetical soil is  26.25 meq/100g.

Explanation:

Average CEC in smectite =  62.5 meq/100g. Since it ranges from(25-100 meq/100g)

Average CEC in kaolinite = 10 meq/100g.

Average CEC in organic matter = 325meq/100g.

Range(250-400 meq/100g).

Estimated CEC for given soil will be,

=30\% \times\ avg.\ CEC\ in\ smectite + 10\% \times \ avg.\ CEC\ in  \ kaolinite +2\% \times avg\ CEC\ in\ organic\ matter.

= 0.3\times 62.5 + 00.1 \times 10 + 0.02\times 325

= 26.25 meq/100g.
