Question

label the diagram below with the correct names of the layers of the earth and their densities. 1. use the terms mantle, outer core, crust, and inner core to label the diagram. 2. locate density ranges of each layer using page 11 of your esri. density is a measure of the amount of matter in a material in a given amount of space. it is a measure of the mass per unit volume of a material. density can only change if you change the pressure or temperature of a material. pressure causes the matter in a material to squeeze closer together and take up less space. increased pressure causes the density of a material to increase. increasing the temperature of a material causes atoms to spread out or expand and take up more space. increasing temperature causes density to decrease. cutting a material into smaller pieces does not change the density of the material. this is because the atoms are still arranged in the same way (they are not expanding or squeezed together). analysis questions: 1. you calculated the density of granite. based on this density, what layer of the earth do you think the granite could represent? explain. 2. what layer(s) of the earth could the steel and hematite represent? explain. 3. what happens to density the deeper you go into the earth? explain why this might be. 4. does cutting a material in half change its density? explain why or why not

Explanation:

1. Granite has a density similar to the Earth's crust. The crust is composed of rocks like granite and basalt. Its density range is generally 2.2 - 2.9 g/cm³, which is in line with granite's density characteristics.
2. Steel and hematite are dense materials. The outer - core and inner - core have high densities due to the presence of iron and nickel. Steel is an iron - based alloy and hematite is an iron - oxide mineral, so they could represent the outer or inner core.
3. As you go deeper into the Earth, density increases. This is because of the increasing pressure. Deeper layers have more overlying mass pressing down, which squeezes the material into a smaller volume, increasing density.
4. Cutting a material in half does not change its density. Density is a characteristic property of a material, defined as mass per unit volume. Cutting the material changes both the mass and the volume proportionally, so the density remains the same.

Answer:

1. The crust. Because granite's density is similar to the density range of the crustal rocks.
2. The outer - core or inner - core. Because steel and hematite are dense like the iron - nickel materials in the core.
3. Density increases. Due to increasing pressure that compresses the material.
4. No. Since cutting changes mass and volume proportionally, keeping density constant.
