The illustration shows a fossil of a dinosaur skull. Which of the following best describes why this fossil is not made of bone but rock?
The dinosaur ate many plants that contained minerals.
The dinosaur died when a rock fell on it and crushed it.

Students notice a fossil of seaweed in a rock found in the middle of Georgia. What conclusion could they form based on this evidence?
Part of Georgia was once under salt water.
Weathering and erosion break down rocks.
Trees in the forest need sunlight in order to grow.
Ancient animals ate seaweed to get energy.
Students layered a container with sand and soil. They added a small chicken bone between the layers. What step in the process of making fossils does this model?
Plants give energy to animals.
Earthquakes push fossils to the surface.
Parts of a living thing are buried.
Water carries minerals through soil.
What can we learn from studying the fossils in a certain area?
How much sunlight the area receives at noon
The direction the wind used to blow in the past
How much rain fell in the area last year
The kinds of animals that lived there
The first step in the process of how fossil are formed is _________
As time passes, sediment hardens into rock, layering on top of the animal or plant part. The remains slowly fossilize in the ground becoming part of the rock.
An animal dies.
The animal's body or plant's leaves are covered by sediments.
The soft tissues are decomposed or destroyed.
The second step in the process of how fossils are formed is _______
As time passes, sediment hardens into rock, layering on top of the animal or plant part. The bones or shells decay into minerals, joining the rock.
An animal dies in a wet environment (such as a riverbank)
The animal’s body or plant’s leaves are covered in mud. Soft tissues or organs decompose or are eaten by other living things.
The hard parts are left behind. (bones, teeth, claws, beaks, etc.)
