rocks are a kind of structure & sedimentary rock is a kind of rock ->  sedimentary rocks are a kind of structure  sediment is formed by rocks weathering & weathering is a kind of erosion ->  sediment is formed by erosion  sediment is formed by erosion & in the formation of sedimentary rock , erosion is the first stage ->  in the formation of sedimentary rock, erosion forms sediment  in the formation of sedimentary rock, erosion forms sediment & erosion causes deposition ->  in the formation of sedimentary rock, sediment formed by erosion is deposited  in the formation of sedimentary rock, sediment formed by erosion is deposited & in the formation of sedimentary rock , burying the sediments follows depositing the sediments ->  in the formation of sedimentary rock, sediment is deposited then buried  in the formation of sedimentary rock, sediment is deposited then buried & sedimentary rocks are formed by sediment cementing together ->  in the formation of sedimentary rock, sediment is deposited then buried then cemented together  sedimentary rocks are a kind of structure & in the formation of sedimentary rock, sediment is deposited then buried then cemented together ->  sedimentary rocks are a kind of structure that is formed by sediments being deposited then buried then cemented together  sedimentary rocks are a kind of structure that is formed by sediments being deposited then buried then cemented together & sediment is a kind of material -> sedimentary rocks are a kind of structure that is formed by materials being deposited then buried then cemented together
