(Print) Use this randomly generated list as your call list when playing the game. There is no need to say the BINGO column name. Place some kind of mark (like an X, a checkmark, a dot, tally mark, etc) on each cell as you announce it, to keep track. You can also cut out each item, place them in a bag and pull words from the bag.

The very first life that evolved in the oceans
prokaryotic cells without a nucleus
a probable cause of the extinction of dinosaurs and the end of the Mesozoic
asteroid
A cause of environmental change whose effect on climates can cause mass extinction
continental drift plate tectonics
Based on the age of these materials, Earth's age was determined
moon rocks, earth rocks, meteorites
explained by a theory of symbiosis between bacteria
eukaryotic cells with a nucleus
Complex life is relatively recent.
Extinction decreases diversity of life, but diversity rebounds.
The % time humans have been present on Earth
<1 %
The oldest era that includes evidence of life
Paleozoic
Humans are very very very recent.
Our human behavior is causing accelerating extinctions.
evidence from Siberia and the probable cause of mass extinction
Volcanic eruptions
The Earth's formation
4.54 billion years ago
The evolution of simple cells - the first life
3.5 billion years ago
when 50% or more of life's species die out
mass extinction
Goodness Earth is old!
Extinction is a natural process.
The era of humans
Cenozoic
the organization of the Earth's history as recorded in layers of the Earth
Geologic Time Scale
The "middle" era
Mesozoic
The Earth's age wasn't determined until this natural phenomenon was discovered and understood
radioactivity
major time period of Earth history
Eras
The mass extincton 252 mya at the end of the Paleozoic killed off this %
96% of life went extinct
An actual age in years is determined through this method
Absolute Dating
Extinction rates are accelerating and possibly creating this even now
6th extinction?
the matching of similar rock layers that allow a more complete record of time between two or more geographic areas
Correlation
a widespread fossil that lived a short period of time
Index Fossil
When one object or layer is determined to be older than another
Relative Dating
What's oldest is the bottom most layer
Law of Superposition
Complex cells altered the environment in this major way
oxygen buildup in the atmosphere
