of water is its highboiling point. As this graph shows, a molecule as light as H2O "should" boil at around –90°C; that is, it would exist in the world as a gas rather than a liquid if H-bonding were not present. Notice that H-bonding is also observed with fluorine and nitrogen...
But soil isn't static, and there're still other processes that go into the formation of soil: the movement and loss of materials. The soil in any location isn't a uniform mixture. Its composition varies with depth. You see, mineral and organic materials move through soil vertically. ...
But overfishing, rising temperatures, unsustainable coastal development, destructive anchoring practices, high-density tourism, pollution, and changes in the composition of seawater due to the removal of mangroves and seagrasses continue to threaten the health of the reef ecosystem. When coral meets techn...

The chemical composition of spring water may vary in many other ways depending on its geological origin. Principal cations (positively charged ions) may include sodium, potassium, calcium, magnesium, and heavy metals such as iron, zinc, and aluminum. Principal anions (negatively charged ions) may...
Water and its interactions with metals are closely bound up with human life, and the reactivity of metal clusters with water is of fundamental importance for the understanding of hydrogen generation. Here a prominent hydrogen evolution reaction (HER) of single water molecule on vanadium clusters Vn...
Having said that, it should, however, also be recalled that the effect of N deposition on species composition in forests starts at rather low levels, and the apparently positive effect of added nutrients may have a strong negative effect on biodiversity (e.g. Bobbink et al., 1998, 2010; ...
Many of the designations used by manufacturers and sellers to distinguish their products are claimed as trademarks. Where those designations appear in this book, and Addison-Wesley was aware of a trademark claim, the designations have been printed with initial capital letters or in ...

Data were extrapolated globally using three independent volumetric estimates of groundwater discharge to coastal waters...
