D.) A secondary pollutant caused by a chemical reaction between pollutants and light.
Answer:
D. 200%
Explanation:
While Americans constitute the 5% of the world population, they use around the 24% of the world's energy.
Then, if the 100% of the population were like the Americans, we have:
5%*x = 100%
x = 100%/5% = 20
the whole population is 20 times the population of the US, then the total energy used is 20 times the energy used in the US.
Then the energy that the 100% of the population would use is equal to:
20*24% = 480%
So we actually would need like 5 Earths.
The option is 200%
Because if we use too much coal we are wasting fossil fuels and burning coal hurts the environment so the alternative energy sources provide clean energy
<span>Chemical weathering occurs more rapidly in a hot and wet climate. Chemical processes like chemical weathering happens rapidly during high temperature, specifically during warm but damp climates. So, on the first question, the answer is letter A. On the second question, the statement that best describes rill erosion is letter D. Rill erosion is the removal of soil by a running water that cuts and forms small channels into a slope or streamlets.</span>
