Effects of environmental stress
By: Christyl Rivers
Warmer temperatures world-wide and degraded environment are affecting earth in myriad ways. Among these are melting polar ice, rising sea levels, acidification of oceans, increased amounts of heat with diminished ozone layer protection, increased wild fires, storms, vanishing species, and species migration, less arable crop...
Diseased trees could be major source of methane
By: John Atchison
The latest statistics have become quite alarming. Sciencedaily.com posted an article recently that noted that July 2012 was the hottest month on record in the United States. That dates back to 1895, when statistics of this nature began to be kept. Combine that with...
Igneous rocks: Granite
By: Jose Juan Gutierrez
Granite is a course-grained intrusive igneous rock formed by the crystal arrangements of quartz, feldspar, mica, and traces of other minerals. Granite is a plutonic rock which usually forms deep inside the Earth’s crust from the crystallization of molten magma. Based on their chemical...
