Unprecedented melting of Greenland ice sheet occurring
By: A.W. Berry
Greenland's ice is melting, however the speed at which this is occurring is debated. According to National Public Radio, a scientist named Ian Joughin of the University of Washington arrived at a net rate of 30 percent after analyzing ice sheet melt data with his...

The United Kingdom's not happy with the position of the jet stream. Storm after storm after storm's been flowing along the jet stream, pounding the UK with unrelenting rain. London could really use a break from all the rain before the 2012 Olympic Games become...
Metamorphic rocks: Marble
By: Hortense Foster
Nature made marble is a rock created by a metamorphism process of sediment carbonate rocks, such as limestone and dolomite rocks. When this change occurs, a recrystallization of the original rock occurs. The marble name was created from the Greek word Marmaton which is from...
Metamorphic rocks: Schist
By: Anja Poulsen
Schists are a group of metamorphic rocks which are medium to coarse-grained and of a fissile nature, meaning that at least one of the minerals in the rock crystallizes in platy form. Because of this, schists will split easily along these parallel layers. In fact...

Quartzites are metamorphosed sedimentary quartz sandstones. Deep in the earth, rocks are heated by molten. Pressure comes from layer upon layer of rocks. Heat and pressure may cause chemical changes within the parent rock. The parent rock, sandstone, now becomes a different rock, quartzite. Erosion...
