5. Please read the following statement and explain your answers thoroughly.
Mercury contamination was detected in Florida Everglades sediments by the State Environmental Department during the environmental quality assessment. The Department was puzzled about this finding because, the currently known industries in the area do not use mercury in their operations and there is no illegal dumping of medical waste containing mercury. So how did Mercury get there?
Knowing the physical and chemical nature of mercury, describe your theories on the source and origin of mercury in the Everglades sediments.
a. Do you think, it was transported across the state or interstates and deposited; if so
b. What are its sources?
c. How did it get transported and deposited?
d. What governed the transportation?
e. If it is not transported, do you think mercury occurrence could be indigenous to the Everglades, if so what is the source?

Past Climate Change: What has caused the Earth's climate to change throughout its history? How has it changed?
Recent Climate Change: How has the climate changed in the last 100-150 years? What has caused the changes?
Future Climate Change: How might climate change over the next 100 years and why?
State of Knowledge: What aspects of climate change do we understand best? What are the most significant uncertainties?
