The Rock Cycle is Earth's great recycling process where igneous, metamorphic, and sedimentary rocks can all be derived from and form one another. Analogous to recycling a Coke can, where an old can ...

Sedimentary rocks are made up of pieces of older rocks (igneous, metamorphic, and sedimentary) and organic remains (shells, bone, etc.). When rocks break apart from erosion they are transported by ...

Last week, Professor of Earth & Oceanographic Science Rachel Beane, with help from students, gave a talk on the craggy coast of Bailey Island, inviting the public to come learn about the unusual rock ...

Temperature and pressure conditions of metamorphism in the Peavy Node area in northern Michigan have been estimated from the garnet-biotite geothermometer and garnet-plagioclase-aluminosilicate-quartz ...

Rock is a solid mass of minerals that have joined together over time. Geology is the study of how the Earth is formed and the things that happen to the Earth. As part of this, geologists study rocks ...
