Question

The composition of rocks affects their densities and the densities of Earth’s layers. Use what you have learned and the information in the table to answer the question.



In which order would these rocks and minerals be found in the layers of Earth from the crust to the lower mantle?

eclogite, perovskite, rhyolite, stishovite
stishovite, rhyolite, perovskite, eclogite
stishovite, perovskite, eclogite, rhyolite
rhyolite, eclogite, perovskite, stishovite

Answer 1

Answer:

Core, mantle, and crust are divisions based on composition. The crust makes up less than 1 percent of Earth by mass, consisting of oceanic crust and continental crust is often more felsic rock. The mantle is hot and represents about 68 percent of Earth’s mass. Finally, the core is mostly iron metal. The core makes up about 31% of the Earth. Lithosphere and asthenosphere are divisions based on mechanical properties. The lithosphere is composed of both the crust and the portion of the upper mantle that behaves as a brittle, rigid solid. The asthenosphere is partially molten upper mantle material that behaves plastically and can flow. This animation by Earthquide shows the layers by composition and by mechanical properties.

Answer 2

The order in which rocks and minerals are found in the layers of Earth from the crust to the lower mantle is rhyolite, eclogite, perovskite, stishovite. (OPTION D)

Explanation

EARTH SURFACE MINERAL LAYERS -

• Earth's surface is made of three distinct layers that have different compositions and characteristics.
• The layers from deepest to the sallowest are - core, mantle, and crust.
• The crust makes 1% of the surface and the mantle covers 68% of the earth's mass.
• The core is mostly composed of iron metal.
• Earth's crust has a rich composition of igneous rocks.
• Rhyolite and Eclogite are extrusive igneous and metamorphic rocks respectively made of granite and basalt.
• The metamorphic rock undergoes drastic changes to form sedimentary rocks.
• Perovskite exists in lower mantle surfaces due to their density.
• Perovskite is a silicate mineral stable at high temperature and pressure conditions.
• Stishovite is the silicon oxide compound that was first discovered in sandstone.
• It is the main component of the lower part of sedimentary rocks and is also found on the lower mantle surface.
