Which elements are most common in the Earth's crust? What sorts of minerals (i.e., specific families) result from these particularly common elements? What sorts of rocks are most common in the crust as a result?
What will be an ideal response?
Answer: The most common elements are oxygen, silicon, aluminum, sodium, calcium, potassium and magnesium. The most common minerals that result from these elements are silicate minerals, including olivines, pyroxenes, amphiboles, micas, feldspars, and quartz. As a consequence, rocks made of these minerals, such as basalt, granite, schist, and quartz sandstone, are very common in the crust.
