Earth's layers formed as result of differentiation. During differentiation, elements and compounds formed varied layers of miner
als. Minerals with low densities tend to crystalize from magma at cooler temperatures; minerals with greater densities crystalize at higher temperatures. Think about the zones or layers of the Earth. We would expect the rocks in the mantle to have a high proportion of A) finely crystalized, dense minerals. B) heavier, denser minerals such as galena. C) less dense minerals that form rocks such as granite. D) minerals that contain heavy metals such as iron and nickel
D) minerals that contain heavy metals such as iron and nickel
Explanation:
The mantle is the second layer of the earth, located between the earth's crust and core, with depths ranging from 30 km below the crust to 2,900 km and temperatures reaching 2,000 ° C in the deepest regions. Its predominant composition is formed by iron and magnesium silicates.
