The ROCK CYCLE CGC 1D1 Notes
SEDIMENTARY ROCKS:
What are the properties of sedimentary rocks?
Sedimentary rocks often have ____________ trapped within them.
Sedimentary rocks consist of layers of lots of small
particles and are often porous.
THINK: Why are sedimentary rocks near the surface younger than sedimentary rocks deeper
down?
Explain how Sedimentary Rock is formed:
1000
2000
3000
4000
5000
6000
Year
Sedimentary Rocks Continued:
METAMORPHIC ROCK:
How are the properties of metamorphic rocks different from sedimentary rocks?
Metamorphic rocks sometimes show distortions caused by the movements that led to their
formation. This may give rise to _____________ or __________ patterns within the rock.
Metamorphic rocks contain regular layers of crystals that
sometimes have a wavy or zig-zag arrangement.
 Metamorphic rocks are formed by the effect of _____________
______________ and _________________ deep within the Earth.
 These conditions change the structure of existing rocks so that
new rocks are formed.
IGNEOUS ROCKS:
What are the properties of igneous rocks?
The size of the crystals depends on ______ ____________ the igneous rock ______________.
Igneous rocks __________ contain _____________.
Igneous rocks consist of randomly arranged interlocking
crystals.
How are igneous rocks formed?
When magma cools above the surface,
____________ igneous rocks are formed.
When magma cools below the surface,
_____________ igneous rocks are formed.
How is the size of crystals in igneous rocks determined by the rate at which magma cools and
solidifies?
