    In fact, due to long-term impacts on food webs, Nr inputs are widely considered the most critical pollution problem in marine systems. [8] In both terrestrial and aquatic ecosystems, responses to N enrichment vary; however, a general re-occurring theme is the importance of thresholds (e.g., nitrogen saturation ) in system nutrient retention ...

  3. Nitrogen and Non-Protein Nitrogen's effects on Agriculture

    en.wikipedia.org/wiki/Nitrogen_and_Non-Protein...

    Nitrogen leaching occurs when nitrogen compounds, primarily nitrates, move through the soil profile and enter groundwater, potentially contaminating drinking water sources. [2] To mitigate these environmental impacts, various nitrogen management strategies are employed in agriculture.

    Earthquake environmental effects are divided into two main types: Coseismic surface faulting induced by the 1915 Fucino, Central Italy, earthquake. Primary effects: which are the surface expression of the seismogenic source (e.g., surface faulting), normally observed for crustal earthquakes above a given magnitude threshold (typically M w =5.5 ...

    Country Location Date Deaths AN (tonnes) Notes United States Gibbstown, New Jersey : 14 January 1916: 1 1.81 In an evaporating pan of the Repauno works, du Pont Co., 1,800 kilograms (4,000 lb) of ammonium nitrate exploded, possibly caused by a clogged air lance leading to overheating of the nitrate. 1 man was killed and 12 were injured.

  7. Effects of climate change on agriculture - Wikipedia

    There are numerous effects of climate change on agriculture, many of which are making it harder for agricultural activities to provide global food security.Rising temperatures and changing weather patterns often result in lower crop yields due to water scarcity caused by drought, heat waves and flooding. [5]

  8. Quake (natural phenomenon) - Wikipedia

    en.wikipedia.org/wiki/Quake_(natural_phenomenon)

    The largest moonquakes are much weaker than the largest earthquakes, though their shaking can last for up to an hour, due to fewer attenuating factors to damp seismic vibrations. [1] Information about moonquakes comes from seismometers placed on the Moon from 1969 through 1972. The instruments placed by the Apollo 12, 14, 15 and 16 missions ...

  9. Global catastrophe scenarios - Wikipedia

    en.wikipedia.org/wiki/Global_catastrophe_scenarios

    A close pass by a large object could cause massive tidal forces that triggered anything from minor earthquakes to liquification of the Earth's crust to Earth being torn apart, becoming a disrupted planet. Stars and black holes are easier to detect from a longer distance, but are much more difficult to deflect. Passage through the solar system ...
