Question

What information about Earth’s materials can be inferred by their arrangement in layers, as shown here?

Answer 1

their relative densities

Explanation:

The relative densities of the earth's materials can be inferred by the arrangement of the earth layers.

Compositionally, the earth is made up of three distinct layers; core, mantle and the crust.

• The crust is the thin outermost layer of the earth.
• The mantle straddles the zone between the core and crust.
• The core is the innermost layer of the earth.

During the formation of the earth, materials differentiated into different layers based on density.

The densest materials settled in the core and they are made up of iron and nickel metals.

The lightest materials of silicate affinity partitioned to the crust.

The mantle contained materials whose density straddles between the crust and core.

Answer 2

Answer:

Option (1)

Explanation:

The earth is comprised of 3 distinct layers, and they are as follows-

• Crust- It is the most interior layer of the earth, and is comprised of the denser materials and siderophile elements. The density of this layer is about 13 g/cm³.

• Mantle- It is the middle layer comprised of the silicate rocks that are rich in aluminum, iron, potassium, sodium, calcium, magnesium and other important elements. The average density of this layer is 5 g/cm³.

• Crust- It is the outer solid portion of the earth in which the rocks are mostly silicate in nature. It is comprised of both continental as well as oceanic crust. The density of this layer is approximately 2.5 g/cm³ .

Thus, the arrangement of these layers helps in understanding the relative densities of the layers.

Hence, the correct answer is option (1).
