What elements make up most of mantle?
In terms of its constituent elements, the mantle is made up of 44.8% oxygen, 21.5% silicon, and 22.8% magnesium. There’s also iron, aluminum, calcium, sodium, and potassium. These elements are all bound together in the form of silicate rocks, all of which take the form of oxides.

Which of these mineral classes is most common in Earth's crust quizlet?
Silicate minerals are the most common minerals in Earth’s crust. The types of minerals present in a rock gives us information about how that rock formed.
What are the densities of most of the common minerals in Earth's crust?
Mineral Densities Most of the major rock-forming minerals in the Earth’s crust, like quartz, feldspar, and calcite, have very similar densities (around 2.6 to 3.0 g/cm3). Some of the heaviest metallic minerals, like iridium and platinum, can have densities as high as 20.
Why are silicate minerals so common in Earth's crust quizlet?
