The Rock Cycle
Section 6.1

3. Cycles fast: repeat in a short amount of time
A repeating series of events
Duration varies
S-l-o-w: repeat over a long period of time
– millions of years
fast: repeat in a short amount of time
hours, days

4. Types of Cycles
Water
Carbon
Energy

5. ROCK CYCLE

6. The Rock Cycle Definition:
Repeated series of events by which rock gradually and continually changes from one type of rock to another.

7. Rocks are Recycled in the rock cycle
Rocks recycle into other rocks!
During the rocks cycle, rocks are
- formed,
broken down,
reformed
There are only THREE basic types of rocks in the rock cycle.
igneous, sedimentary, metamorphic

8. ??????
Where does
the rock cycle
begin?
end?

9. The Rock Cycle There is no “starting” point
There is no beginning and no end.
The cycle can go in any direction.
It doesn’t have to go “in order”
It is a very S – L – O - W cycle

10. Which type of rock is determined by its ORIGIN.
How it formed. (remember 3 ways that minerals form?? Pg. 97)
Magma below the Earth’s surface is the source of all the Earth’s rocks

11. But… lets start when the earth was molten during the Hadean Era, 3
But… lets start when the earth was molten during the Hadean Era, 3.8 billion years ago

12. Igneous Rocks (#1-15) Magma (molten, liquid rock) rises
As it nears or reaches the Earth’s surface it cools and crystalizes
Solidifies into igneous rock

13. Metamorphic Rock (#16-30)
Rocks get buried deep beneath layers and are exposed to HEAT and PRESSURE
They get chemically and physically changed (morphed) into new rocks.

14. Sedimentary Rocks (#31-45)
At the surface rocks are broken down into smaller pieces (sediments)
by weathering and erosion of WATER, wind or ice
Sediments are layered, buried, compacted and cemented into sedimentary rocks
