This type of rock is formed at or near the Earth's surface by the accumulation and lithification (material is compacted under pressure) of materials. One example of how these rocks form is when materials of existing rocks are weathered and then deposited.

• Igneous rocks

• Metamorphic

• Sedimentary

• Continental

True or false: Fossils are usually found in sedimentary rock.

• True

• False

The relative age of a rock is

• The number of years since the rock formed

• Less than the age of the fossils the rock contains

• Its age based on how much carbon-14 the rock contains

• Its age compared with the ages of rock layers around it
