ROCK CYCLE STUDY GUIDE
MAGMA TYPES (basaltic, granitic) WILL NOT BE ON THE TEST.
1) Where does Earth get the energy to move rocks (matter) from its inside to its
outside?
The Earth’s internal heat energy drives processes such as melting and high
pressure & temperature that change rocks. Earth’s internal energy pushes rock
material to the Earth’s surface.
2) Where does Earth get the energy to cause rocks (matter) to break down at the
surface?
Energy from the sun drives the movement of wind and water that causes the
erosion, and weathering of Earth materials.
3) Where does the energy for all of Earth’s processes come from?
Energy from the Earth’s interior and the sun drive all of Earth processes - like the
rock cycle, and weathering and erosion.
4) Can any rock on Earth can be changed into a new type of rock by processes
driven by the Earth’s internal energy or by energy from the sun?
YES! Any rock on Earth can be changed into a new type of rock by processes
driven by the Earth’s internal energy or by energy from the sun.
5) What is the difference between a rock & a mineral?
Minerals are solid, naturally occurring, inorganic, have a fixed composition and are
made of one or more elements. Rocks are made of one or more minerals.
6) What is limestone if made up of?
The remains of once living sea creatures.
7) What is pressure?
Force that pushes against an object
8) What is the law of conservation of matter? How does it apply to the rock
cycle?
Matter cannot be created or destroyed. Matter is never created or destroyed
during the rock cycle.
9) What are examples of sedimentary, metamorphic and igneous rocks?
Sedimentary – limestone and halite and calcite
Metamorphic – marble and coal
Igneous – basalt and obsidian
10) What are the processes that form detrital sedimentary rocks?
Cementation and compaction
11) What does organic mean?
something that was alive once.
12) How do metamorphic rocks form?
If rocks are buried deep in the Earth at high temperatures and pressures, they
form new minerals and textures all without melting.
13) What processes can Igneous, metamorphic, and sedimentary rocks can ALL be
exposed to?
Igneous, metamorphic, and sedimentary rocks can ALL be exposed to high
temperatures and pressures, weathered and eroded, melted into magma.
14) What is the difference between an extrusive igneous rock and an intrusive
igneous rock?
An extrusive rock is formed on Earth’s surface and has no visible crystals. An
intrusive igneous rock is formed inside of Earth, beneath its surface, and usually
has large visible crystals.
15) What are the most common rocks at Earth’s surface?
Sedimentary
