Nutrient pollution: Causes and consequences
By: Christyl Rivers
Over nutrition of alge by phoshates and nitrates causes Eutrophication and Hypoxia. This means polluted water sources and endangered ecosystems. Eutriphicaiton comes from the prefix, “Eu” meaning good, and trophic, “meaning tending toward.” In other words, in the natural world eutrophication refers...
Arctic ice on pace for record melt
By: Elizabeth M Young
There are at least three Arctic ice melt records that will be broken soon, possibly within the next week. One is for the lowest level of arctic sea ice ever recorded. The others are for the fastest and the most Summer melting ever recorded. From...
Igneous rocks: Gabbro
By: J. Lang Wood
Igneous rocks are those that are formed by the cooling of magma that arises through the crust from the earth’s center. This category include a wide variety of sub-categories, such as felsic, alkic and mafic rocks. Gabbro is named after a town in Tuscany...

Earth scientists separate the Earth's rocks into three general types based on the way in which the rock originally formed. One of those classes, the igneous rocks, includes those that form by cooling from red-hot liquid magma. Igneous rocks are further subdivided based on where...

Earth scientists separate all rocks into three major groups: igneous, metamorphic and sedimentary. At that point, the process of identifying and classifying a rock has just begun. For each of the three major groups, there is a classification scheme to divide its members into ever-smaller...

Terminology that has to do with forest fire suppression includes words and phrases used by botanists, meteorologists and fire fighters. Forest protection managers use the scientific language that has to do with trees and wind direction. Weather language also plays a big part. Managers should...

Silviculture blends the ecology of the forest with economy; finding ways to sustain both. It includes the thinning of the forest to provide areas for other vegetation that wildlife uses. Silviculturists want to see the forests continue for millennia, and they use methods to accomplish...

While the thought of forest fires is anathema to many, especially environmentalists, the fact is that in forested areas, fires are a natural part of the environment. Forest fires are neither innately destructive nor beneficial; it depends largely on where and when the fire occurs...
Explaining biodiversity loss
By: Christyl Rivers
The loss of biodiversity means the loss of all life supported by inter-connected dynamics which supply air, water and nutrients. Biodiversity is in effect, everything evolved on earth that is not mere mineral or inanimate chemical. In school, many students have learned about the food...
