The composition of sedimentary rock shows the source of the sediment that makes up the rock. Which of the following would provide the best evidence of how the rock formed?

• the rock’s age

• the rock’s color

• the rock’s texture

• the rock’s fossil content

Sometimes a fossil is formed as a result of the movement of an organism in soft sediment. Which of the following are two kinds of trace fossils?

• shells and bones

• tracks and burrows

• bee and beetle in amber

• petrified and mummified fossils

The figure shows one type of physical evidence that scientists use to understand Earth’s past. Imagine that you found this evidence on a mountaintop. What could you conclude from your discovery?

• This organism is now extinct.

• This fossil is older than the mountaintop.

• The mountaintop is made of metamorphic rock.

• The rocks on this mountaintop were once at the bottom of an ocean.

Florida was once part of Pangaea, which was a supercontinent that later divided into Africa and South America. Which statement best describes this process?

• A volcanic eruption likely caused Pangaea to divide.

• The continents have been moving throughout Earth’s history.

• Weathering and erosion eventually broke Pangaea apart.

• Africa and South America go through cycles of dividing and colliding.

Sometimes a fossil is formed as a result of the movement of an organism in soft sediment. What type of fossil is this called?

• bone fossil

• trace fossil

• frozen fossil

• petrified fossil
