Complete the flowchart to show how sediment is turned into sedimentary rock and what happens to it at each step.
Sedimentary Rock Formation: Sediment -> Deposition - particles are loosely packed -> a. compaction -> b. cementation -> Sedimentary Rock
Sedimentary Rock Formation: Sediment -> Erosion - particles are broken down -> a. weathering -> b. transportation -> Sedimentary Rock
Sedimentary Rock Formation: Sediment -> Melting - particles are liquefied -> a. cooling -> b. solidification -> Sedimentary Rock
Sedimentary Rock Formation: Sediment -> Metamorphism - particles are altered -> a. heat -> b. pressure -> Sedimentary Rock

Circle the letter of each sentence that describes a way that chemical rocks can form.
a. Minerals that are dissolved in a solution crystallize.
b. Sediments of plants and animals form oil and other chemicals in rock.
c. Mineral deposits form when seas or lakes evaporate.
d. Tiny particles of clay are cemented together with chemicals.

gypsum
Sandstone and limestone have been used as building materials for thousands of years because:
they are abundant and easy to work with.
they are rare and expensive.
they are only found in specific regions.
they are not durable.
Builders today use sandstone and limestone in various ways, including:
as primary materials for constructing buildings and monuments
for decorative purposes in interior and exterior design
in the production of cement and concrete
all of the above
Is the following sentence true or false? Limestone is used for making cement.
True
False
