1. 1. Formation
a. Weathering
b. Erosion
c. Deposition
d. Compaction
e. Cementation
*LITHIFICATION=process to
make sedimentary rocks*

2. a. Weathering – the breakdown of
material at the Earth’s surface.g
i. The
weathered
material is
called
SEDIMENT.

3. Did you Know?
¾ of rocks on
the Earth’s
surface are
sedimentary?!
?!

4. ii. Sediment
size varies –
mud, sand,
gravel

5. b. Erosion – movement of
sediment from on place to
another by WIND, WATER, or
ICE.

6. c. Deposition – dropping off the
sediment in a new location.

8. Now it’s time to put them
together!
d. Compaction (Squeezing)
e. Cementation (Gluing)

12. A. Clastic
Made from
sediment
such as
clay,
gravel, or
sand

13. i. Sand becomes
sandstone

14. Did you Know?
The white
house is built
of
sandston
e!

15. ii. Clay and mud become shale

16. iii. Gravel becomes
conglomerate.

17. B. Organic sedimentary rock is
formed from previously living things.
i. Limestone –
ocean life
ii. Coal – plant life
on land

18. 4. Chemical sedimentary rock is
formed from a chemical reaction such
as water evaporating and leaving rocks
behind.

19. i. Mineral
crystals left
behind in Death
Valley after the
water
evaporates
ii. Playa Lake in California
– in the process of
evaporating and leaving
chemical rock behind
