From Sediment To Rock
Sediment rocks form from particles deposited by
____________ and _______________.
Sediment is _____________, __________________ pieces of
material that come from ______________ or _____________
things.
Water, _____________, and ________ can carry sediment and
deposit it in _______________.

Deposition
Deposition is the process by which ________________
settles out of the _____________ or _____________ carrlying
it. (The moving water or wind slows and deposits the
sediment.)
Different types of sediment are
______________________________________________
_______________________________.
Compaction
Before compaction occurs, the following steps take place:
1. Sediments fit _______________ _________________.
2. Thick layers of sediment __________________ _______.
3. These layers are heavy and _______________ down on the
______________ beneath them.
4. Then, __________________ occurs.
Compaction is the process
__________________________________________________.
Cementation
Cementation is the
_______________________________________________________
___________________________________________________.
This means that while compaction is taking place, the
minerals in the rock slowly dissove in the water and seep
into the spaces between particles of sediment.
This process often takes millions of years to work.
Types of Sedimentary Rock
There are three major groups of sedimentary rocks:

Shale feels smooth, and splits easily into flat
pieces.
Sketch rock:
Sandstone forms from the sand on beaches, on the ocean
floor, in riverbeds, and in sand dunes.
Sandstone can easily ______________ water through
these holes.
