What layer is the most dense layer of Earth?

• Crust

• Mantle

• Outer core

• Inner core

What happens to the temperature and density as you go deeper down into the Earth's layers?

• Temperature increases, density decreases

• Temperature decreases, density increases

• Temperature increases, density increases

• Temperature decreases, density decreases

What caused Earth to form into layers?

• Earth melted and more dense material sank, less dense material moved to the outer layers.

• The sun cooked it and then it cooled.

• Asteroids hit the earth forcing material inside.

• A lack of pressure from space forced the materials into layers.

What is the unit for density?

• grams/cubic centimeter (g/cm3)

• grams/milliliter (g/mL)

• grams

• milliliter

• volume

What units are used to measure mass?

• g
• cm³
• g/cm³
• cm³/g

What is the formula for density?

• density = mass x volume
• density = mass / volume
• density = mass + volume
• density = mass - volume

An object has a density of 5g/mL and a mass of 10g. What is the volume?

• 50 mL

• 2 mL

• 15 g/mL

• 2 g/mL

What is the density of an object that has a mass of 6g and a volume of 2cm3? AND will it float in water if the density of water is 1g/cm3?

• 12g/cm3

• 3g/mL

• 3g/cm3

• Yes, it will float

• No, it will sink,

Look at this image.  Which object has the LOWEST density in water? How? 

• The Ping Pong Ball because it floats to the top 
• The bolt because it has sunk to the bottom
• The soda cap because it is not just full of air like the Ping Pong ball

Which liquid has the highest density? 

• corn syrup
• lamp oil
• rubbing alcohol
• honey
