Minerals are typically formed when molten rock, or magma, cools, or by separating out of mineral-rich water, such as that in underground caverns. In general, mineral particles are small ...
The Science Education Center houses thousands of rock and mineral samples in what is known as "The Rock & Mineral Room." The entire collection can be viewed by clicking on each of the virtual drawers ...
Petrology is the study of rocks - igneous, metamorphic, and sedimentary - and the processes that form and transform them. Mineralogy is the study of the chemistry, crystal structure and physical ...
As children grow, it’s important for them to get enough vitamins and minerals to ensure optimal health. Most kids get adequate amounts of nutrients from a balanced diet, but under certain ...
Rocks have become life. As rocks erode and flow into the oceans and weather into soil, their minerals provide vital nutrients that underpin both the abundance and evolution of life. In turn, life has ...
Some minerals in rocks and organic matter (e.g., wood, bones, and shells) can contain radioactive isotopes. The abundances of parent and daughter isotopes in a sample can be measured and used to ...
Rocks and minerals hold precious clues about how Earth formed and evolved over billions of years — but what is the difference between the two? In essence, rocks are aggregates of two or more ...
The best vitamins for kids contain essential nutrients to help them grow and develop. A well-balanced diet provides the ideal source of these vitamins and minerals, but some children may need ...
Rocks are composed of different minerals. Sometimes, this is obvious, as they show up in big crystals. Other times, it is not ...
Primary minerals form at elevated temperatures from cooling magma during the original solidification of rock or during metamorphism, and they are usually derived from igneous and metamorphic rocks ...
Tiny minerals are revolutionizing our understanding of textbooks. Easter Island consists of several extinct volcanoes. The ...
But tonight, it's a little different. Onstage, rocking out to Michael Jackson's "Beat It," is a band made up of School of ...
