The negatively charged oxygen atoms in our air are attracted to the positively charged copper atoms in the penny. When oxygen binds with copper, they form a new molecule known as copper oxide. This is why most pennies you see look dirty or tarnished, it's actually copper oxide. Silver will not oxidize as quickly, as it is not made of a material that negatively charged oxygen atoms are attracted to.

Many marine organisms depend on up welling to bring nutrients to the surface. How might El Nino affect a fisherman's way of life

svp [43]

During an El Nino, warm water gathers along the West coast of South America, so the nutrient rich water is no longer being upwelled. keeping in mind that cold water sinks and warm water rises, usually the warm water near coastal regions would not be full of nutrients compared to the cold water where the nutrients fall. therefore, more fish will be located or migrate to areas of this nutrient rich cold water instead. So, many fishermen would not have high yields of fish ultimately affecting their way of life and money. also a lot of these fish that remain at the surface would not be as healthy or nutrient rich.

hope that helps! :))
