Question

the composition of rocks affects their densities and the densities of earths layers. use what you have learned and the information in the table to answer the question.

rock/mineral	density (gm/cm³)
perovskite	4.03
rhyolite	2.50
stishovite	4.29

in which order would these rocks and minerals be found in the layers of earth from the crust to the lower mantle?
o eclogite, perovskite, rhyolite, stishovite
o stishovite, rhyolite, perovskite, eclogite
o stishovite, perovskite, eclogite, rhyolite
o rhyolite, eclogite, perovskite, stishovite

Explanation:

The Earth's crust is composed of less - dense rocks, and as we move towards the lower mantle, the density of rocks increases. Comparing the densities of the given rocks/minerals: rhyolite (2.50 g/cm³) is the least dense, followed by eclogite (3.45 g/cm³), then perovskite (4.03 g/cm³), and stishovite (4.29 g/cm³) is the most dense. So, from the crust to the lower mantle, the order is from least - dense to most - dense.

Answer:

D. rhyolite, eclogite, perovskite, stishovite
