Most sedimentary rocks
are formed through a
series of processes :
Erosion, deposition,
Compaction, and
Cementation
From Sediment to Rock.
Erosion
Running water wind or ice
loosen and carry away
fragments of rock

From Sediment to Rock.
Deposition
Process by which
sediment settles out of
the water or wind
carrying it

From Sediment to Rock.
Compaction
The process that presses
sediment together in
thick layers that build
up gradually over time

From Sediment to Rock.
Cementation
The process in which
dissolved minerals
crystallize and glue
particles of sediment
together

Types of sedimentary Rock

There are three main
types of sedimentary
rocks.
Clastic Rocks, Organic
Rocks, and Chemical
Rocks
Types of sedimentary Rock
Clastic Rocks
Sedimentary rock that
forms when rock
fragments are squeezed
together

Shale, Sandstone,
Conglomerate, and
breccia
Types of sedimentary Rock
Organic rocks
These types of rocks form
when the remains of
plants and animals are
deposited in thick
layers.

Coal (swamp plants)
and
Limestone (sea creatures)
Types of sedimentary Rock
Chemical Rocks
When minerals that are
dissolved in solution
crystallize

Uses of Sedimentary Rocks
People have used
sedimentary rocks
throughout history for many
different purposes, including
building materials and tools.
Example
 flint for arrowheads
 Limestone for cement and
steel
