The Flint Michigan water Crisis was a very big problem that Flint faced. What happened was Flint was previously using Detriots water and they chose to switch to another water source. The compony that Flint chose to get there water from hadn't finished building pipes to go into Flint which lead Flint to the problem of where to get their water from. They chose to use a lake close to them but after a while, citizens started to notice the water smelled, looked, and tasted funny. The city denied these comments to be untrue but more and more people were reporting this. This is where the chemistry comes in, so the water had a lot of this organic molecule called trihalomethane which can cause liver, kidney, lung, and heart problems. The water also, had lead which is also very bad. The way lead got in the pipes was because the pipes were made out of lead because of its durability. Tons of lead was entering each home and it became a big problem. All of this could of been prevented if the city paid more attention to the pipes where they got there water from, etc. This event showed how important it was to make sure your water was safe and drinkable and to pay attention to hydrology.
This video/article shows you the path that the carbon can take to get back to the atmosphere. So for example, a plant could take the CO2 in from photosynthesis and realse it when an animal eats it. After the animal eats it dies and realeses it back into the atmosphere. The Carbon cycle is important because it shows how much carbon is in the atmosphere and since carbon realeses heat causing global warming.
This rap does a good job explaining each layer of the atmosphere, and hey its catchy. To start the Troposphere is where all living organisms and weather is located. Next the Stratosphere is where the ozone is located which protects us from the suns rays. After that there is the Mesosphere which protects us from meteoriods from hitting us. Then there is the Thermosphere which is the hottest layer in the atmosphere due to lack of molecules. Finally there is the Exosphere which is the outmost layer and is where the satollites are located
