1. Explain the rock cycle?
A continuous process that causes rock to
change from one form to another.
2. Rock
Any solid mass of minerals or mineral-like matter
3. Do most rocks occur as one
mineral or as a mixture of minerals?
4. Some rocks are made of nonmineral material, can you name one?

The Rock Cycle is a group of changes, this change does
not necessarily have to be a chemical change.
Igneous rock can change into sedimentary rock or into
metamorphic rock.
Sedimentary rock can change into metamorphic rock or
into igneous rock.
Metamorphic rock can change into igneous or
sedimentary rock.
Almost all of rock today that we have on earth is made
up of all the same stuff as the rocks that dinosaurs and
other ancient life forms walked, crawled, or swam over
Over time rocks are recycled into other rocks
Moving tectonic plates are responsible for destroying
and forming many types of rocks
List the 3 types of rocks
List the 3 types of rocks
Look at the granite rock and the rhyolite rock
Granite
Rhyolite
In what ways are the two rocks similar?
15. In what ways are the two rocks different?
Granite
Rhyolite
Granite – coarse texture, made from magma
Rhyolite – fine texture, made from lava
16. What causes the two rocks to be different?
Granite
Rhyolite
Granite – Slow cooling below the earth’s surface
Rhyolite – Quick cooling on the earth’s surface
Classifying Rocks
Rocks can be
classified by looking
at the rocks texture,
mineral composition,
and color.
Question
Slow cooling magma will form rocks
with a
a. coarse grained texture.
b. fine grained texture.
c. glassy texture.
d. porphyritic texture.
What is texture?
The size, shape, and pattern of the rock’s grain
Glassy
(nice)
Composition (what it is made of?)
The minerals that make up the
different parts of a rock
Examples are:
Quartz
Feldspar
Magnesium
Iron
