What type of rock contains fossils of organisms you might find at the beach?
sedimentary
igneous
metamorphic
minerals
How do geologists determine the age of rocks?
index fossils (used to identify a geologic period)
relative dating of sedimentary rocks (tells the order of the rocks)
radioactive dating of rocks (detects carbon in the rock)
relative dating of igneous rocks (tells the order of the rocks)
Which statement represents the Law of Superposition?
The rock layers closest to ground level have more fossils than the top layers
The layers that are darker in color are the oldest
The layers that are lighter in color are the oldest
The rock layers closest to the ground are older than the top layers
How can scientist learn about the past by studying Sedimentary Rocks?
how a species has changed over time
how animals made a shelter
the colors of plants
how many hearts a dinosaur has
An unknown mineral can be scratched by topaz but not feldspar. Which of the following might be the hardness of the mineral?
more than 6
more than 8
less than 8, but more than 6
more than 4, but less than 6
In this picture, what is the best evidence that one of the layers was formed under an ocean?
the layers
the thickness of the layers
the height above sea level
the type of fossils within the layer
What type of rock is shown from the layers in the image?
intrusive
foliated
sedimentary
metamorphic
Based on the chart, identify an unknown mineral that is white in color, pearly luster, and a hardness level of 1.
talc
calcite
muscovite
quartz
A student is trying to identify a mineral that has a nonmetallic luster and is black. It can also be scratched with a fingernail. The unidentified mineral is most likely (Hint: remember the mineral that would peel super easy)
mica
quartz
calcite
magnetite
The cooling rates of an igneous rock relies on
the rock's composition
the rock's grain sizes
the rock's density
the rock's reaction to chemicals
How does the intrusive igneous rock Granite form?
it cools quickly under the Earth's surface
it cools slowly under the Earth's surface
it cools quickly on the Earth's surface
it cools slowly on the Earth's surface
The diagram shows fossils in two different rock sections. Which layer in site 1 is close in age to layer Z in site 2?
G
F
E
D
Which statement is true about how rocks form?
Weathering and erosion prevent magma from changing into igneous rock.
Heat and pressure cause metamorphic rock to weather and erode.
Weathering and erosion can change sedimentary rock into sediment.
Heat and pressure can change igneous rock to sedimentary rock.
A rock sample will most likely include?
water
bugs
minerals
plants
Limestone is a sedimentary rock that can be metamorphosed into marble by
weathering
cementation
melting
pressure
Where will an igneous rock most likely form?
in a volcano

deep on the ocean floor
at the bottom of the river
Which is a characteristic of a mineral?
it has different colors
