The Rock Cycle
Thinking about relationships among
the major rock groups
If you are watching as a
PowerPoint ,watch it correctly
… or it won’t make sense!
• Turn on the volume.
• On the top menu, make sure you click “Slide
Show” then click “From Beginning” before
watching.
• The “Enter” key will take you to the next slide
when you are ready.
• The back arrow key will allow you to go back if
you need to.

Take Notes
As you go through the PowerPoint write a definition
for each type of rock. Then copy the detailed
diagram of the rock cycle, like the one in the PPT.
You do not need to draw all the pictures, just the
diagram and vocabulary terms.

Major Rock Groups
• Igneous
– Formed from a molten rock
– Intrusive (plutonic):slow cooling inside earth and crystallization
– Extrusive (volcanic): quick cooling at the surface
• Sedimentary
– Formed at the Earth’s surface
– From mineral or rock fragments & grains, clays, or precipitates
• Metamorphic
– Undergoes extreme pressure, temperature .

The Rock Cycle
Is the continuous process by
which new rocks form from old
rock material.

In Conclusion…
• The rock cycle demonstrates
the relationships among the
three major rock groups
• It is powered by the Earth’s
heat
• It involves processes on the
Earth’s surface as well as
the Earth’s interior
• It connects the “water
cycle” with the “tectonic
cycle”.
