Transcript of Sedimentary rocks

Sedimentary rocks
Are rocks made of SMALL, SOLID PIECES, (or sediments) of material that come from rocks or living things.


HOW ARE ROCK SEDIMENTS FORMED AND HOW DO THEY BECOME ROCKS??
EROSION
EROSION is caused by destructive forces that are always breaking down rocks, and then carry these broken sediments of rocks away....(think of when you erase something with your eraser)
The destructive forces constantly wearing away all of the rocks on the Earth's surface are:
Heat
Cold
Rain
Waves
Ice

DEPOSITION
is the process where sediment settles out of the water or wind carrying it
COMPACTION
layers of sediments are piling on top of one another pressing down on the lower (older) layers of sediment pressing them together


CEMENTATION
During compaction minerals in rock slowly dissolve in water. These minerals then seep in between the sediments and crystallize gluing the particles of sediment together
in 4 steps starting with:
this process takes millions of years
There are 3 Types of Sedimentary Rocks
1. Clastic
2. Organic
3. Chemical
CLASTIC ROCKS
a sedimentary rock that forms when rock fragments are squeezed together. These fragments can be microscopic to boulder sized.
Examples:
SHALE-from tiny clay particles
SANDSTONE-small particles of sand
CONGLOMERATE-different sized rok fragments with ROUNDED edges
BRECCIA-SHARP edges
ORGANIC ROCKS
Are sedimentary rocks formed where the remains of plants and animals are deposited in thick layers
Examples:
COAL-from the remains of swamp plants buried in water
LIMESTONE-hard shells of living things
CHEMICAL ROCKS
sedimentary rocks that form when minerals that are dissolved in a solution crystallize.


EXAMPLES:
GYPSUM-formed by evaporation
ROCK SALT-mineral deposits left when seas or lakes evaporate
SEDIMENTARY ROCKS
they are classified based on the type of sediments that make up the rocks
