Reorder the steps to show the process that led to the formation of sedimentary rock.

• minerals act like cement and hold the sediment together to form sedimentary rock

• weathering creates sediment

• sediment settles on land, lakes, or rivers

• new layers of sediment press down on the old layers

• After a long time, the sediment is pressed together

Reorder the following to show the process of oil formation.

• Marine plants and animals die and settle on the bottom of the seabed.

• Oil forms a reservoir after moving through the porous rock.

• The layer of plants and animals get covered with a layer of mud.

• Over time, layer after layer of sediment creates pressure and compresses the dead organisms into oil.
