mudstone
Sedimentary rocks are formed because of
compaction and cementation
compaction and compression
compression and pressure
heat and cementation
What are tiny bits of minerals called?

rock stuff
cement
sediment
What makes sediment?
pieces of rock, sand, and dirt
pieces of glitter
pieces of plaster of Paris
pieces of pumpkin pie
Which diagram models compaction?
Sand in the sediment melts and turns into rock.
The weight of the water compacts the sediment into rock.
Changing water temperatures turn sand in the sediment into rock.
Pollution caused by humans turns the sediment into rock.
Deposition is
When slowing water lays down sediments to form beds
Squeezing of sediment grains together by the weight of sediments above
Precipitation of minerals that "glue" the sediment grains together
When tectonic plate movement raises buried rocks up to the surface
What is the process of moving sediments from location to another?
Deposition
Erosion
Weathering
Compaction
The process by which rocks are broken down
Weathering
Deposition
Erosion
Sedimentation
The process in which wind, water, ice or gravity transport rock fragments from one location to another
Weathering
Sedimentation
Erosion
Deposition
The process in which sediment settles out (drops to the bottom) of the water or wind that is carrying it
Weathering
Erosion
Sedimentation
Deposition
How does sediment build up?
day by day
row by row
layer by layer
slice by slice
This process "glues" the particles of sediment together:
cementation
compaction
calcification
weathering
________ is fuel formed from the remains of organisms that lived long ago

Which layer of rock is the oldest?
A
B
C
D
Fossil trees were discovered in a sedimentary rock layer. In the rock layer below are fossils of clams, similar to clams found on the shores of the Gulf of Mexico. Based on this evidence, we could conclude that the area where the fossils were discovered had what environments in the past?
Sea followed by Forest
Forest and later than a mountain
Forest followed by Beach
Tundra followed by forest
This table gives information on different fossils. According to the information in the table, finding which fossil in a region would lead to the conclusion that the area was, long ago, covered in trees?
Snail Shell
Scorpion
Dragonfly
Millipede
This rock contains fossils of water plants and shells. What does this tell us about the rock?
The rock contains many living things
The rock was once in the middle of the forest
The rock is heavier than most rocks
The rock was once at the bottom of the sea

What causes the compaction & cementation steps for the formation of a sedimentary rock?
Heat from sun
Heat from inside Earth & pressure from layers above over millions of years
Time
They just randomly happen
Several layers of sedimentary rock are illustrated. They are in the same order as when they first formed. Which layer formed first?
Rock Layer A
Rock Layer B
Rock Layer C
Rock Layer E
Oil formation occurs where, millions of years ago, there were large oceans. This is because oceans have –
waves that are constantly moving.
great numbers of tiny marine animals.
currents that mix the water thoroughly.
deep caverns where no light can reach.
Oil formation starts when organisms in the ocean die and then –
get eaten by larger organisms that receive their energy.
are carried by currents all over the planet.
decay completely so that their matter is recycled.
settle to the bottom and are buried in sediments.
The diagram shows layers deposited under bodies of water. This layering continued for millions of years. What most likely happen to the dead plants and animals?
They were eaten by scavengers.
They became fossil fuels.
They were washed away by water.
They became underground aquifer.
Which diagram models the process of compaction leading to the formation of sedimentary rock?
Which list contains only processes that must occur in order for fossil fuels to form?
Formation of faults, burial, glacial formation
Organism growth, burial, volcanic activity
Organism growth, burial, compaction
Erosion, burial, earthquakes
The model shows a process that took place over time. Which process will this most likely represent?
The erosion of a coastline
The deposition of sediments
The weathering of a mountain
The formation of a sea
If looking at layers of sediment in the Earth, which layer is the youngest?
the top
the middle
the bottom
second to the top
What processes happen inside the Earth when making sedimentary rocks?
weathering
deposition
