SEDIMENTARY ROCKS are classified by the types of sediments that make up the rock
Sediments
What are
sediments?
Def: small, solid pieces of material that come from rocks or other living things (may
include shells, bones, leaves, stems, etc
Processes
Erosion
(wash away)
How sediments form into sedimentary rock: Write the steps in order w/descriptions
Deposition
(drop down)
Forces – running water, wind, or ice loosen & carry away fragments of rock
Sediments settle out of the water or wind carrying them & they sink to the bottom of
the lake or ocean
Compaction
(smashed
together)
Process that presses sediments together. Thick layers of sediment build up over time &
weigh down the layers compacting the sediments.
Cementation
(glued
together)
Process in which dissolved minerals crystallize & glue particles of sediment together,
dissolved minerals seep into the spaces between particles & then harden
Types
Clastic Rock
(Define each type:
Def: Made from rock fragments that
are squeezed together.
Give details about how each type forms:
Shale - forms from tiny particles of clay
Sandstone - forms from sand on beaches, ocean
floor, river beds, etc.
Conglomerate - forms from rounded sediment.
Breccia - forms from larger, sharp fragments of
sediments.
Organic Rock
Chemical
Rock
Uses
Building
Materials
And Tools:
Fossils 
Def: Forms where the remains of
plants & animals are deposited in
thick layers
Coal – forms from swamp plants buried in water for
Def: Forms when minerals that are
dissolved in a solution crystallize
Limestone – forms from calcite in dissolved seas,
millions of years.
Limestone – forms in the ocean from hard shells with
calcite from seashells, coral, clams & oysters or
skeletons that pile up on the ocean floor for millions
of years slowly changing the sediment to limestone
lakes & underground caves.
Rock Salt – forms from halite by evaporation
What things have been made from sedimentary rocks?
Flint – Arrowheads
Sandstone – The White House
Limestone - used as blocks & slabs for buildings, making cement & steel
