The relationship between the properties of matter and the structure of the Earth. -mass, volume, density, Earth’s interior, atmosphere

Matter has mass What is mass?

Matter has volume What is volume?

Measuring Mass Which instruments at your experiment stations would you use to measure the mass of … a solid? a liquid? A gas?

Measuring Volume Which instruments at your experiment station would you use to measure the volume of………. a regular shaped solid? an irregular shaped solid? a liquid? a gas

Density What is the meaning of density? What other measurements do you need to calculate density? What is the formula for density? What are the densities of common Earth materials…. water?air?rocks?

Density Density is a specific property of matter. Matter can be identified by its density. Density is a comparison of a substance’s mass compared to its volume. The formula for density is – Mass divided by volume. Density is most commonly written as g/cm3 or g/mL. Earth’s materials layer by their densities.

Calculating density At your experiment station, find the density of the three items at your station. List the mass of each item The volume of each item Figure the density of each item (Make sure that you use the correct tools to calculate your answers).

Soils and Streambeds Soils and streambeds are sorted by density and particle size. How do they sort if the settling is vertical? How do they sort if the settling is vertical? How do they sort if the settling is horizontal?

Sorting of Earth’s Materials List areas on Earth where materials are sorted by density and particle size. In what circumstances would they be sorted by particle size? In what circumstances would they by sorted by density?

Earth’s Interior Structure What is the order of the densities of the interior structure of the Earth? How does this relate to their positioning?

Earth Interior Model Draw a picture of Earth’s interior Describe how these layers are layered by density. Label the four main layers of the Earth (crust, inner core, outer core, mantle) Give the specific densities of the layers. How can the inner and outer core be made of the same materials and yet differ in their states of matter?

Density of Earth Layers The average densities are as follows: Crust: 2.8 g/cm3 Mantle: 3.35 g/cm3 Outer Core: 11.0 g/cm3 Inner Core: 14.0 g/cm3
