7.2.4 Earths Layers and Density

What is Density?

• How much space an object take up.

• How much matter makes up an object.

• How much gravitational pull an object has.

• How compact the particles of an object are.

What is the formula for finding Density?

• Mass times volume

• Volume time mass

• Mass divided by volume

• Volume divided by mass

What is the Density of an object with a mass of 20 g and a volume of 10 mL?

• 1 g/mL

• 2 g/mL

• 3 g/mL

• 4 g/mL

What is the density of an object that has a volume of 25 mL and a mass of 75 g?

• 3 g/mL

• 2 g/mL

• 1 g/mL

• 0.05 g/mL

What is the Density of an object that has a mass of 500 g and has the dimensions of 5 cm, 5 cm and 10 cm?

• 1 g/mL

• 2 g/mL

• 3 g/mL

• 4 g/mL

What is the volume of an object if a beaker has 500 mL of water in it, but when you add the object, goes up to 1000 mL?

• 500 mL

• 700 mL

• 1000 mL

• 2000 mL

Select the correct formula for finding the Density of an object with a mass of 500 g and when put in a beaker of water with 50 mL and rises to 100 mL.

• 500 g x 50 mL = 25000 g/mL

• 500 g / 100 mL = 5 g/mL

• 500 g / 50 mL = 10 g/mL

• 50 mL / 500 g = 0.1 g/mL

What are the 3 layers of the Earth and the sublayer?

• Crust, Mantle, Apple Core, Inner Core

• Bread Crust, Mantle, Core, Inner Core

• Crust, Manteau, Outer Core, Apple Core

• Crust, Mantle, Outer Core, Inner Core

Which layer of the Earth is least dense?

• Crust

• Mantle

• Core
