
From where do scientists get their (1)
DIRECT evidence and (2) INDIRECT
evidence that shows that Earth is
composed of layers…
(1) Direct evidence comes from actual rock

Next Question
Stay Classy! – 10 points


Igneous rock that cools inside Earth is
called ___________, while igneous rock
that cools outside Earth’s surface is called
_____________.
Intrusive; extrusive
Next Question
Stay Classy! – 20 points


When all the grains of a rock are large and
easy to see, we say the rock has a
_______ _______ texture.
Coarse grained
Next Question
Stay Classy! – 30 points


You are observing a rock that was formed
under great heat and pressure deep within
Earth. Its minerals appear to be arranged
in parallel bands. What type of rock is it?
Foliated metamorphic
Next Question
Stay Classy! – 40 points


Extrusive igneous rock is most likely to
have a ________-grained texture. WHY?
Fine; because it cools outside Earth’s
surface and therefore cools so quickly that
there is not time for large grains to form
Next Question
Stay Classy! – 50 points


Intrusive igneous rock is most likely to have
a ________-grained texture. WHY?
Coarse; because it cools inside Earth’s
surface and therefore cools more slowly,
giving time for larger crystals to form
Next Question
You Sed It! – 10 points


When a rock fragment separates from the
“mother rock” due to atmospheric
conditions, we call it ___________.
Weathering
Next Question
You Sed It! – 20 points


A piece of sediment has just gone through
the process of deposition. What did it do?
It came to rest in a new place after eroding.
Next Question
You Sed It! – 30 points


You are observing a rock that appears to
have shell fragments cemented together.
What type of rock is it? How do you know?
Organic sedimentary; made from
cementation of remains of once-living
things
Next Question
You Sed It! – 40 points


State the 5 things (in order) that occur as a
sedimentary rock is formed.
Weathering, erosion, deposition,
compaction, cementation
Next Question
You Sed It! – 50 points


You are observing a rock that has very
large chunks of sediment compacted
together. Classify this rock using at least 3
vocabulary terms.
coarse grained, clastic, sedimentary rock
