 Biochemical(organic) sedimentary rocks are formed from by organisms or contain the remains of organisms
Chemical sedimentary rocks form when minerals crystallize directly from water.
Clastic sedimentary rocks are made up of broken pieces of minerals and rock fragments.

Chalk is a pure white form of
limestone. Most school chalk these
days isn’t made out of the rock chalk;
it is made of mineral powder clued
together. Marine fossils can often be
found in chalk. Clastic

Shale is made up of layers of silt, clay,
and mud from ancient rivers and lakes.
The green-gray layers can be split
apart easily. Shale is used to make
bricks. Fossils and ancient animal
tracks/burrows are sometimes
preserved on shale. Rock salt is a sedimentary rock that
forms from the evaporation of salt
water. It is also known by the mineral
name halite. Rock salt is a rock that
you can eat! LIMESTONE

Limestone is made mostly of the
mineral calcite. Sea creatures use
calcite use it to make their shells.
After the creature dies, their shells
become cemented into grey limestone.
Many buildings, are made out of
limestone. Biochemical

When you touch sandstone, it feels
gritty because this rock forms from
grains of sand cemented together by
hardened minerals. Sometimes you
can still see ripple marks from waves
in sandstone. Sandstone is used for
building. CONGLOMERATE

Shiny, black coal isn’t formed from
pebbles or sand. It’s made of dead
swamp plants. Pressure and heat
compacted plants into coal millions of
years ago. Sometimes coal contains
fossils of these ancient plants. Coal is
burned to produce electricity. Biochemical

Find conglomerate rock and you will
see different-colored, rounded
pebbles cemented together. This
rock formed from fast flowing rivers
or beaches with strong waves.
Conglomerate can be used to make
concrete.
