100
This is the approximate age of Earth.
What is 4.6 billion years old?
100
Identify one form of evidence that scientists use to know about the different climates that Earth has experienced in the past
What is (multiple answers: Rocks, Fossils, Landscape - mountains, valleys, glaciers, etc.)?
100
This is the idea that the processes occurring in the present are the same as the process that occurred in the past and will continue to occur in the future.
What is uniformitarianism?
100
This is process by which organisms that are best adapted to their environment survive and reproduce, passing their traits on to their offspring.
What is natural selection?
100
This law states that in an undisturbed horizontal sequence of rocks, the oldest rock layers will be on the bottom, with successively younger rocks on top of these.
What is the Law of Superposition?
200
This era had the longest duration in geologic time.
What is Precambrian?
200
This is an example of an organism that has gone extinct.
What is (multiple answers: Woolly Mammoth, dinosaurs, trilobite, ammonite, etc.)?
200
This evidence is needed to prove that Mason, OH was once covered in water.
What is a fossil of an aquatic organism/plant?
200
The Industrial Revolution caused England's nearby forests to be coated with black soot. Out of the two morphs of Peppered Moths, which population would decrease due to this change?
What is light moth population?
200
This type of fossil is most useful in determining the relative ages of the rocks layers.
What is index fossil?
300
These are the four geologic time eras.
What is Precambrian, Paleozoic, Mesozoic, Cenozoic?
300
This would most likely happen over time to a species without variation when there is a significant change in the environment.
What is extinction?
300
Identify and describe one possible explanation for mass extinctions.
What is (multiple answers: Climate Change, Meteorite Impact, Widespread Disease)?
300

This is a trait that helps an organism to be successful in its environment.

What is an adaptation?

300

A radioactive substance is used for this.

What is to determine the absolute age of a rock/fossil?

400
This Cenozoic era is often called "The Age of ______".
What is Mammals?
400
According to the fossil record, __% of organisms that lived on Earth are extinct.
What is 99%?
400
Use the principle of uniformitarianism to make an inference about a modern whale species and its ancestor the "walking whale".
What is the "walking whale" inhabited land and over many generations, it began to inhabit an aquatic environment and slowly changed its skeletal form.
400

In order for natural selection to take place, this must be present within the population of a species.

What is VARIATION?

400

This principle of cross-cutting relationships states this.

What is any fault or intrusion that cuts across a layer is younger than that layer?

500
This is how scientists determine when a geological era begins and ends.
What is changes in the fossil record?
500
Identify two pieces of information the fossil record provides about past life.
What is (multiple answers: the structure of organisms, what they ate, what ate them, in what environment they lived, and the order in which they lived)?
500
This evidence explains how ancient coral reef fossils can be found high in the mountains far from any sea.
What is land that was uplifted to form the mountains was once covered by the sea?
500
Under ideal conditions, bacteria have a generation time of about 20 minutes. Humans have a generation time of about 20 years. Which would you expect to evolve faster?
What is bacteria? (Their populations go through so many more cycles of reproduction. More new species gives more chance of evolution)
500

These are two characteristics of a good index fossil.

What is it is only found in one layer and also in many locations?
