Total questions: 30
Worksheet time: 22mins
Which extinction is considered the largest mass extinction in Earth's history? Basically 96% of all species on Earth disappeared.
Ordovician Extinction
Devonian Extinction
Permian Extinction
Triassic Extinction
Cretaceous Extinction
According to most scientists, what is the ultimate cause of most mass extinctions?
overhunting
evolution of new species to replace old ones
major change in environment or climate
asteroid impact
True or False: Human beings are wiping out species much faster than nature creates them, causing what scientists call a "6th extinction"
true
false
There have been 5 mass extinctions in Earth's history. Which of the following answer choices was a cause of these extinctions? You may select more than one answer. Check all that apply.
increased carbon dioxide (CO2) levels in the atmosphere
an asteroid impact
widespread volcanic activity
All of them
What classifies a mass extinction?
Only 5% of species go extinct.
Massive flooding due to hurricanes.
Happens in a relatively short period of time and is global
There have never been any mass extinctions on Earth.
Which of the following is NOT an accepted criterion for a mass extinction event?
The event must have occurred in a relatively short time frame.
The extinction involves multiple lifeforms and is widespread.
A significant part of life on Earth became extinct.
The cause of the mass extinction must be obvious.
Cyanobacteria photosynthesize and created waste gases which led to what???
The great nitration event
The great oxygenation event
The great carbon dioxide event
The great ozonification bifurcation event
What is the main evidence for the great oxygenation event?
Fossils known as BIF's
Formations of rock known as the Banded Iron Formations
BUF's
Formations of rock known as the Banded Iridium Formations.
Layered rock formations that are produced by a type of bacteria. The bacteria needs water, carbon dioxide, and sunlight to slowly make this rock.
stromatolites
biosignature
psychrophiles
halophiles
Which of the following might happen as part of normal background extinction?
When all the species in a particular area on earth suddenly go extinct
When multiple species from all over the earth suddenly go extinct
When one species goes extinct due to habitat changes
When all life on earth is wiped out
The red layers in banded iron formations are rust, which forms when which two chemicals combine?
iron and carbon dioxide
iron and oxygen
oxygen and carbon dioxide
methane and sulfur dioxide
The oldest fossil evidence of early life on Earth would be
banded iron formations
stromatolites
meteorites
impact craters
Which of the following describes coevolution of a BIOTIC (living) thing with an ABIOTIC (non-living) thing? (SELECT ALL THAT APPLY)
an invasive insect causes mass die-off of a crop species
a reduction of plants in a field leads to increased soil erosion
increased soil erosion leads to a nearby stream becoming muddy
clogged and polluted streams cause a fish species to go extinct
Cyanobacteria photosynthesize and created waste gases which led to what???
The great nitration event
The great oxygenation event
The great carbon dioxide event
The great ozonification bifurcation event
What is the main evidence for the great oxygenation event?
Fossils known as BIF's
Formations of rock known as the Banded Iron Formations
BUF's
Formations of rock known as the Banded Iridium Formations.
True or False: The first organisms in the ocean did not use oxygen.
True
False
Which gas did organisms in the sea take out of the air?
Oxygen
Carbon Dioxide
Nitrogen
Sulfer
What layer of the atmosphere does oxygen help make up?
ozone
mesosphere
stratosphere
troposphere
How did organisms use the oxygen from the Great Oxygenation Event?
For cellular respiration
For homeostasis
For photosynthesis
For mitosis

Which of the following is a man-made cause of extinction?
impact from an asteroid or comet
competition among species
global cooling during ice ages
habitat destruction
