What is a mineral's luster?
how it reflects light
if it breaks along even surfaces
the color of its powder
if it can scratch other minerals
A mineral can scratch another mineral if its hardness is: (choose all answers that apply)
greater than that mineral's hardness
equal to that mineral's hardness
less than that mineral's hardness
A student rubbed a mineral on a porcelain plate and observed the color of its powder. What property were they testing for?
streak
hardness
cleavage
luster
Which of these statements accurately describes a physical property and a chemical property?
A physical property changes the substance, while a chemical property doesn't.
A chemical property changes the substance, while a physical property doesn't.
Both physical and chemical property change the substance.
Neither a physical property nor a chemical property will change the substance.
Which of the following tests involves a chemical property of a mineral?
finding the streak of the mineral
adding a drop of acid to see if the mineral reacts
observing the mineral's luster
determining the mineral's density

streak
luster
hardness
cleavage
The diagram shows layers of sedimentary rock with fossils in them. The layers have not been overturned. Which fossil is the oldest?
Why are fossils useful to scientists? (choose all answers that are correct)
They show what life was like in the past.
They help them to match up rock layers.
They provide evidence for continental drift.
They provide evidence for evolution.
Which type of rock is most likely to contain fossils?
igneous
metamorphic
sedimentary
The large crack in these rock layers that has displaced them is the result of a process known as:
erosion
faulting
tilting
folding
how would you determine the density of a mineral sample?
mass divided by volume
volume divided by mass
mass times volume
mass plus volume
Which property describes the ability of a mineral to break along even edges?
luster
hardness
streak
cleavage
The rock layers in the picture have:
been tilted
had an igneous intrusion
been faulted
been folded
