| The answer is A Horizon (keep the thread going by asking a question after you answer). O Horizon is the first layer which is organically rich (ex: consists of leaves)
Question: This is the layer in the atmosphere where the Aurora Borealis (northern lights) form. |

| The ENSO is an oscillation of the ocean-atmosphere system in the tropical Pacific. It is caused by oceanic and atmospheric circulation.
Next Question: What are some of the consequences of losing biodiversity? | |

Next Question: This disaster was when a Japanese petrochemical and power company dumped estimated 27 tons of mercury into Minamata Bay. Thousands of people developed "Minamata disease" and over 900 people died. (Name the City, Country) | |

specialist would be screwed.also, environmental degradation. food webs and chains would mess up etc
Explain the difference between stratospheric and tropospheric ozone.Also, describe the process in which tropospheric ozone is created.(chemical equations are good as well) | |

| stratospheric ozone = good b/c it captures UV rays
tropospheric ozone = bad b/c it is a powerful oxidizing agent that can form toxic compounds with other chemicals.. leads to creation of smog
tropospheric ozone is created when nitrogen oxides and volatile organic compounds react with sunlight in the troposphere | |
