Think About It…
What is the ultimate source of
all solid, non-living material
on Earth?

How Igneous Rocks Form …
• How do igneous rocks form? 1. Igneous rocks are
formed from the crystallization of magma.
2. Three factors that affect magma formation are
1. temperature
2. pressure
3. water content

Practical Uses of Igneous
Rocks… Practical Uses of Igneous Rocks…
1. As construction materials – granite
2. As valuable ore deposits – silver, gold, lead, copper
3. Pegmatites contain gemstones
4. Kimberlites contain diamonds. See next slide.

Kimberlites • In South Africa in the
1860’s, it was
discovered that
kimberlites were the
source of diamonds.

“sediments”
means…
– Pieces of solid
material
deposited on
Earth’s surface

How Sedimentary Rocks
Form…
1.Rocks are weathered meaning…
–Big pieces are broken down into smaller pieces. Arches National Park in Utah –
weathered rocks become arches!

Importance of Sedimentary Rocks…
1. Sedimentary rocks
often contain
fossils which can
give us clues to the
past.

Classification of Sedimentary Rocks… Clastic (broken)
1. Coarse-grained- conglomerate (gravel/pebbles)
2. Medium-grained – sandstone (sand)
3. Fine-grained – shale (clay)
4. These form when broken pieces of sediment are cemented together.

Chemical
1. Calcite - limestone
2. Halite – rock salt
3. Gypsum – rock gypsum

Classification of Sedimentary Rocks… Organic (from living things)
1. Shells – coquina limestone (shells & calcium carbonate)
2. Plant matter (swampy) – coal
3. These form from living things that get turned into
rock!

About Metamorphic Rocks…
• Metamorphic is
Greek for…
– change in
form

How Metamorphic Rocks
Form…
A metamorphic rock forms when high temperatures
and pressure combine to alter the texture,
mineralogy, or chemical composition of a rock
WITHOUT MELTING IT!

How Metamorphic Rocks
Form…
• Three types of
metamorphism may
change rocks…
a. Regional
b. Contact
c. Hydrothermal

Practical Uses of
Metamorphic Rocks…
1. Contain economically
valuable minerals –
talc and garnets
2. Marble is used in
sculpting.
3. Deposits of gold, and
lead are formed by
metamorphism.

Classification of Metamorphic Rocks…
• Foliated…
– Have wavy layers or bands that are caused by minerals with flat crystals that form long axes perpendicular to the pressure
1. Slate from shale
1. Schist from shale (buried
deeper)
2. Gneiss from granite

Classification of Metamorphic Rocks…
• Nonfoliated…
– Lack mineral grains with long axes in one
direction. They form minerals that have
blocky crystal shapes.
2. Marble from limestone
1. Quartzite from sandstone
3. Hornfels from basalt

Think About It…
How could you turn any rock
into an igneous rock?

Focus Question…
What are the processes that
turn one rock into another?

The Rock Cycle…
• How are igneous rocks formed?
– By melting, cooling, and crystallization
• What happens to igneous rocks that undergo
weathering and erosion?
– They become sediments
• How do sediments become sedimentary rocks?
– By deposition, burial, and lithification
(compaction and cementation)

The Rock Cycle (continued)…
• What forces cause sedimentary rocks to be
transformed into metamorphic rocks?
– Heat and pressure – without melting!
• How can metamorphic rock be transformed into
igneous rock?
– By melting, cooling and crystallization of
magma
• How can sandstone be transformed into
sediment?
– By weathering and erosion
