Clastic means

• Broken pieces of older rock

• old rocks that have not broken down

• weathering

• erosin

Clastic sediment is called ________ because it is composed of silicate materials (igneous rock)

• ignoclastics

• facies

• siliciclastic

• biofacies

How are clastics (siliciclastic) rock classified?

• type of rock fragment

• size and composition of the clast (rock fragment)

• sze only

• what the chemical composition is

the process that breaks down rocks, soils, and minerals into smaller pieces, but it does not involve the movement of those materials away from their original location (unlike erosion). 

• lithosphere

• erosion

• sediment

• weathering

Breaking rocks down without changeing their chemicl composition

• chemical weathering

• physical weathering

• erosion

• fragmentation

changing the composition of rocks through chemical reaction like sightly acidic rain

• chemical weathering

• physical weathering

• erosion

• fragmentation

formed by the compaction and cementing together of sediments. These rocks can be formed from erosion and weathering of other rocks

• Igneous rocks

• Sedimentary rocks

• Metamorphic rocks

• Volcanic rocks

Facies, lithofacies and biofacies are ______

• types of fragmentatoin

• types of rock

• weathering techniques

• sedimentary environments

A place where sediment is deposited

• erosion

• wind belt

• facies

• fossilcies

•Defining a facies based on the fossils found

• fossilcicies

• Lithofacies

• Biofacies

• facies
