What is the chemical composition of quartz?
GeologyQuartz is made of the two most abundant chemical elements on Earth: oxygen and silicon. Atoms of oxygen and silicon join together as tetrahedrons (three sided pyramids). These stack together to build crystals. Billions of tetrahedrons are needed to build even a small crystal. What are some chemical properties of quartz? Quartz Physical Properties Chemical

How are clints and Grikes formed?
GeologyA is a limestone pavement which is formed when the joints in the limestone are dissolved away by the rainwater. Limestone is dissolved because rainwater is a weak carbonic acid. The joints which are widened and deepened by this chemical weathering are called grikes. The blocks which stick up are called clints. Where do Grikes

What is the difference between P waves and S waves?
GeologyP waves can travel through any media (including liquid and gas), but S waves can only travel through solid media like rock. P waves travel faster than S waves. The difference in travel times can be used to determine the epicenter of the earthquake. What are three differences between P and S waves? Body waves
