Sequence 3.1 Test Review

How do you calculate density?

• d = m + V

• d = m - V

• d = m x V

• d = m ÷ V

Mr. McAcy found a big rock with a mass of 75 g and a volume of 100 cm³.

What is the density of the rock?

• 175 g/cm³

• 0.75 g/cm³

• 1.33 g/cm³

• 25 g/cm³

"Felsic" lava has a density of 2.7 g/cm³ and "Mafic" lava has a density of 3.0 g/cm³.

Which type of lava will sink in the other?

• Felsic lava

• Mafic lava

• Neither...they're both lava

Object A has a mass of 3 g and Object Z has a mass of 300 g.

Which object will float in water?

• Object A

• Object Z

• Both objects

• Neither object

• Not enough information

S-waves cannot pass through liquid.

Where will you NOT find S-waves?

• Crust

• Upper Mantle

• Lower Mantle

• Core

Earth is divided into three parts--the crust, mantle and core--based on...

• Chemical makeup

• State of matter

• Volume

• Magnetic Field

Which of these is NOT evidence of the Earth's layers?

• Not all seismic waves make it through the Earth

• Earth has a stronger gravitational pull than if it were made of only crustal rock

• Physical samples of each layer show different chemical makeup

• Earth has a natural magnetic field that is detectable everywhere

Which is the correct relationship?

• When temperature increases, density decreases.

• When temperature increases, so does density.

• When temperature increases, mass decreases.

• When temperature increases, so does mass.
