It really is the end of the world as we know it. Watch this Ted video to learn some reasons why. Although it is the end of the old world, for many optimists it is the beginning of a new, and improved world. The fact...
An overview of ocean biogenic sediments
By: Jose Juan Gutierrez
Biogenic sediments are the skeletal remains of either plant or animal marine species. The hard skeletal structures of marine organisms are important constituents of the deep ocean sediment and many layers of the deep ocean floor are almost entirely composed of calcareous and siliceous skeletal...
Facts about marine sediments: Pelagic sediments
By: Jose Juan Gutierrez
Pelagic sediment comprises fine-grained material composed of lithogenous, biogenous, and cosmogenous particles that have been deposited in the ocean floor away from the neritic zone. Pelagic sediment is composed of calcareous and siliceous shells from marine organisms, fine-grained clay material, volcanic ash and trace amounts...

A large amount of plant species are invasive in the southern United States. Many of them are native to moist, warm climates similar to the southern states. Invasive plants can be anything from trees to shrubs, vines, grasses, and other types of plants. These exotic...
Facts about marine sediments: Biogenous deposits
By: Jose Juan Gutierrez
Biogenic deposits are fine-grained red, brown or light-colored skeletal remains of planktonic organisms that have been deposited on the ocean floor. Biogenic deposits are referred to as oozes. There are two different groups of biogenic oozes; calcareous oozes and siliceous oozes. Biogenic deposits of biogenic...

The anatomy of a water molecule
By: Jose Juan Gutierrez
Water (H2O) is the most abundant molecule on Earth. Water covers approximately 70% of the Earth´s surface. The oceans contain about 96.5% of all water on the planet and 3.4% is found in lakes, rivers and ice glaciers; the remaining 0.001%...
An overview on hydraulic fracturing
By: Joseph Tamone
Hydraulic fracturing is the process of creating, and then reproducing a series of fractures within a well. Millions of gallons of fracturing fluids are then mixed with a proppant material, and pumped into the well. Hydraulic fracturing produces a highly permeable drain that can increase...
