Why is the word "metamorphic" appropriate for rocks of that type?
it describes all types of rocks
It is a scientific term
there aren't many metamorphic rocks on Earth
To "morph" means to change
The presence of igneous rocks in an area is most likely evidence of:
dinosaurs
sedimentary rocks
volcanic activity
sediments
How are rocks classified?
by the way they form
by the way they look
by the layers present
by the way a geologist says
What physical properties help identify minerals?
hardness, color, luster, streak
hardness, texture, color, magnification
hardness, color, magnification
hardness, texture, elements
The term foliated in rocks describes the ____ present in metamorphic rocks
colors
elements
layers or bands (ribbons)
colors and elements
What is the process that occurs when the weight of sediment layers above press down on the layers below, squeezing the particles together?
compaction
melting
heat & pressure
cooling
Which of the following best describes the luster of a mineral?
the color of a mineral
the way the mineral reflects light
the crystal shape
the chemical composition
Which of the following explains why oceanic plates subduct?
continental crust is thicker and denser than oceanic crust
oceanic crust is thinner and less dense than continental crust
continental crust is thinner and less dense than oceanic crust
oceanic crust is thinner and denser than continental crust
Why is streak an important physical property used to help identify minerals?
streak identifies the hardness of a mineral
streak reveals the true shape of the sediments
streak shows the true color of a mineral
streaks relates color to the elements present
What must have occurred to an igneous rock during formation?
it formed from magma cooling
it formed 1 million years ago
it formed 250 million years ago
it formed by sediments
Intrusive igneous rocks are rocks that formed
by cooling inside the earth
by cooling outside the earth
by cooling in layers
by cooling with multiple colors of minerals present
Extrusive igneous rocks are rocks that have formed
while cooling outside the earth
while cooling inside the earth
while in the ocean
while at the top of a mountain
How are sedimentary rocks formed?
by heating and cooling deep underground
by compaction and cementation of sediments
by cooling of magma or lava
by heat & pressure
How are metamorphic rocks formed?
by heating and cooling deep underground
by cooling of magma or lava
by compaction and cementation of sediments
by heat and pressure
How are igneous rocks formed?
by heating and pressure deep underground
by compaction and cementation of sediments
by cooling of magma or lava
by heat and pressure
Sedimentary rocks can have layers of different colors. This occurs when –
molten rock seeps into large cracks underground
extreme pressure causes minerals to separate
different minerals are deposited at different times
seasonal patterns change the rate of erosion
In order to be classified as metamorphic, a rock must have –
magma cooling underground
changed with heat and pressure
compacted sediment into layers
formed in less than 2 years
Where continental plates diverge, what rock type will most likely result?
metamorphic
sedimentary
sediments
igneous
Which of the following is one of the final processes in the formation of igneous rock?
cooling
cementation
heating
compaction
What is a mineral?
a solid at the bottom of a lake
an inorganic, naturally occurring substance
the three types of rocks all in one category
an organic substance
