Math Journal Prompt:
All the 5th graders at Ella’s school are
going on a field trip to Bush Gardens. There are
180 people going on the trip. Each bus holds 40
people. How many buses are needed? Explain
why your answer makes sense.
Don’t Forget, restate the
question with your answer and
justify it.

Sedimentary Rocks
• Igneous rocks are the
most common rocks on
Earth, but because
most of them exist
below the surface you
might not have seen
too many of them.
• 75 percent of the rocks
exposed at the surface
are sedimentary rocks.
What is sediment?
• Sediments are loose materials such as
rock fragments, mineral grains, and bits of
shell that have been moved by wind,
water, ice, or gravity.
• Sediments come from already-existing
rocks that are weathered and eroded.
• Sedimentary rock forms when sediments
are pressed and cemented together, or
when minerals form from solutions.
Sedimentary Rocks
Sedimentary rocks may be made of rock
fragments—sediments—or by chemical
reactions. The classification of sediments
is shown below.
Clastic rocks–made of cemented
sediments—are classified by their grain sizes.
Non-clastic rocks form by chemical precipitation
(settling out from a solution.) Limestone is made
from calcite, chert from quartz, and halite is rock
salt.
Biologic sedimentary rocks come from
the remains of organic matter.
• The most important of
these is coal. Anthracite
coal results from the
greatest pressure and
releases the most energy
when burned. Other
varieties are bituminous
and lignite. “Petrified”
(permineralized) wood is
another organic rock.
More about sedimentary rocks
• Shale is the most
common sedimentary
rock
• Sedimentary rocks
cover about threequarters of the land
surface

Radiometric dating provides an
accurate way to estimate the age of
fossils.
• Relative dating estimates
the time during which an
organism lived.
– It compares the placement
of fossils in layers of rock.
– Scientists infer the order in
which species existed.

Close your eyes and imagine:
As the bulldozer dug up your back yard,
you happened to notice an interesting rock. It
appeared to have an outline of a squid.
Think-Pair-Share:
• What type of rock could it be and why?
• What could you infer about what your
backyard looked like a million years ago?
What is the scientific
theory that the Earth’s
crust is broken up in to
plates that move or float?
Plate Tectonics
What is the crust and
upper mantle called?
lithosphere
What is the rock that is
made from melted rock
(called magma) that has
cooled and hardened?
igneous
What’s a solid nonliving
substance found inside of rock?
mineral
What is the rock that is made from
small pieces (called sediment) that
have pressed and cemented
together called?
sedimentary
What’s the hottest and
hardest layer at the center
of the Earth called?
inner core
