• without cracks, fossils could not get into them

• they have cracked from being so old

• they are formed from deposited layers of sediments

Sedimentary rock forms when...........

• sediments get compacted and cemented together

• sediments get worn off of a cliff

• rockslides happen

• erosion carries pieces of rock away
