How can fossils help us understand past environments?
By showing the colors of ancient plants
By providing evidence of the types of organisms that lived and their habitats
By indicating the age of the Earth
By revealing the diet of modern animals
Which condition is necessary for an organism to become a fossil?

Living in a forest
What can the presence of marine fossils in a desert tell us?
The desert was once underwater
The desert is very old

Develop a model to describe how a fish might become fossilized.
The fish swims in the ocean forever
The fish is eaten by a predator
The fish dies, sinks to the bottom, and is buried by sediment

To see how deep the ocean is
To find water
What evidence can fossils provide about extinct animals?
Their favorite food
Their size and shape
Their favorite color
Their speed
How can the study of fossils help us predict future changes in the environment?
By showing us what animals will look like

By telling us what the weather will be like tomorrow
By showing us how to build better houses
What information can fossils provide about ancient climates?
The speed of ancient winds
The color of ancient skies
Evidence of past climate conditions and changes
The temperature of the Earth today
Why are fossils found in sedimentary rocks more often than in other types of rocks?
Because sedimentary rocks are the hardest
Because sedimentary rocks are found only in deserts
Because sedimentary rocks are the oldest
Because sedimentary rocks form in layers that can preserve remains
