Iron

Iron

Iron is a chemical element with symbol Fe (from Latin ferrum) and atomic number 26. It is a metal in the first transition series.It is by mass the most common element on Earth, forming much of Earth's outer and inner core.It is the fourth most common element in the Earth's crust.Its abundance in rocky planets like Earth is due to its abundant production by fusion in high mass stars, where it

Volcanic gases Overview sandatlas

Volcanic gases are volatile substances released from a volcano or volcanically active area. Volcanic gases are always involved in volcanic eruptions, but they are often given off by passively degassing (dormant) volcanoes as well.

Blood Gases   Lab Tests Online

Blood Gases Lab Tests Online

Blood gases are a group of tests that are performed together to measure the pH and the amount of oxygen (O 2) and carbon dioxide (CO 2) present in a sample of blood, usually from an artery, in order to evaluate lung function and help detect an acid base imbalance that could indicate a respiratory, metabolic or kidney disorder.. A person's body carefully regulates blood pH, maintaining it

7. Dimension 3 DISCIPLINARY CORE IDEASEARTH AND SPACE SCIENCES. E arth and space sciences (ESS) investigate processes that operate on Earth and also address its place in the solar system and the galaxy. Thus ESS involve phenomena that range in scale from the unimaginably large to the invisibly small.

The bioleaching of sulphide minerals with emphasis on

The most successful copper heap leaching operations have been those processing copper oxides and secondary copper sulphides ().Chalcocite (Cu 2 S) is the main copper sulphide mineral mined at bioleaching operations. Some of the chalcocite heap operations began as oxide (chemical) leach operations and were converted to bioleach (oxidative) operations by heap aeration and/or inoculation,

Carbon dioxide in Earth's atmosphere

Carbon dioxide in Earth's atmosphere

Carbon dioxide concentrations have shown several cycles of variation from about 180 parts per million during the deep glaciations of the Holocene and Pleistocene to 280 parts per million during the interglacial periods. Following the start of the Industrial Revolution, atmospheric CO 2 concentration increased to over 400 parts per million and continues to increase, causing the phenomenon of

Minerals, Rocks & Rock Forming Processes

Minerals in the Earth's Crust. There are more than 3000 known minerals (the number is still growing), but of these only about 20 are very common, and only 9 of these constitute 95% of the crust.These 9 minerals are all silicates, and are also called the rock forming minerals.They can be subdivided into two groups, the mafic and felsic minerals according to the principal rocks types they mainly
