Unit 2: Earths Layers Flashcard

Front

What is density?

Back

Density is a measure of how much mass is contained in a given volume. It is calculated using the formula: density = mass / volume.

Front

What is the formula for calculating density?

Back

density = mass / volume

Front

If a liquid has a mass of 9g and a volume of 3mL, what is its density?

Back

3 g/mL

Front

Why do helium balloons rise in the air?

Back

Helium balloons rise because helium is less dense than air.

Front

What two layers make up the lithosphere?

Back

The lithosphere combines the Crust and the Upper Mantle.

Front

Put the following liquids in order from most dense to least dense: 4, 3, 2, 1.

Back

4, 3, 2, 1

Front

What happens to the density of an object if its mass increases while its volume remains the same?

Back

The density of the object increases.

Front

What happens to the density of an object if its volume increases while its mass remains the same?

Back

The density of the object decreases.

Front

What is the relationship between density and buoyancy?

Back

An object will float if it is less dense than the fluid it is in, and sink if it is more dense.

Front

What is the density of water?

Back

The density of water is approximately 1 g/mL.
