We ROCK!
I only believe in science
...that old fossil
Its about time
Layers upon layers upon layers...

The three types of rocks.
What are igneous, metamorphic, and sedimentary?
100
The four branches of scientific study involved in research about biological origins
What are:
Evolutionary Biologists
Molecular Biologists
Biogeographic Researchers
Paleontologists
100
These are the three different ways fossils are formed in sediment.
What is:
Permineralization
Impression
Preservation
100
The_________ is the history of life as preserved by fossils and documented by scientists.
What is fossil record?
100
When layers of sedimentary rock are originally deposited horizontally; any tilting happened later; seen in the image below.
What is original horizontality?
100
The death of every member of a species from loss of habitat, changes in local environment or the introduction of a new competitor can cause ________.
What is extinction?
200
Rocks that have been transformed over time from one type of material to another. They either began as igneous or sedimentary rocks.
What are metamorphic rocks?
200
These scientists look for similarities and differences in the genes of diverse organisms.
What are molecular biologists?
200
This is fossilized feces, a type of trace fossil.
What is a corprolite?
200
This compares one rock or fossil to another to determine which one is older.
What is relative dating?
200
Layers of rock are continuous until they encounter other solid bodies or acted upon after they are deposited, as pictured below.
What is lateral continuity?
200
When a great many species go extinct in a relatively short period of time.
What is mass extinction?
300
Rocks form when magma or lava cools and crystalizes.
What are igneous rocks?
300
These scientists look for traces of the history of life in fossils.
What are paleontologists?
300
Buried organisms decompose and leave an empty space-a mold. Minerals fill the empty space or sediment may fill the mold-a cast. Footprints, skin, feathers and other evidence of organism activity form molds-trace fossils.
What are impression fossils?
300
A timescale that estimates the intervals of time from the Earth’s formation to the present day using the sciences of stratigraphy and paleontology.
What is geological timescale?
300
Intrusions (igneous rock) are the most recent of the layers it disturbs, as seen below.
What are cross-cutting relationships?
300
The theory most scientists endorse through scientific evidence which supports that all the organisms around today came from an original creature cell, or self-replicating RNA.
What is the Evolutionary Theory?
400
Rocks form on or near the surface of the Earth from the compression of sediments. Erosion and weathering break down large rocks into sediment that make up these rocks.
What are sedimentary rocks?
400
These scientists study similarities in the features and embryonic development of species.
What are evolutionary biologists?
400
This type of fossil forms when an organism is buried quickly in a low-oxygen environment. This prevents decomposition, giving lots of information about the organism.
What are preservation fossils?
400
A method used to estimate the age of rocks and of the fossils in each layer of rock by measuring how much of the radioactive material in the rocks or fossils has broken down or decayed into more stable elements.
What is radiometric dating?
400
The oldest layer of rock is on the bottom. Like a pile of dirty clothes, as seen below.
What is superposition?
400
A consumer, such as a bacterium or fungus, that breaks down dead organic matter and returns the nutrients and minerals they contain to the soil.
What is a decomposer?
500
The formation of rock from clay, sand and other sediments on the bottom of the ocean or other bodies of water.
What is lithification?
500
These scientists study the distribution of species and ecosystems over the Earth and through time.
What are biogeographical researchers?
500
In these types of fossils, water carrying minerals soak into the cells of plants, the water evaporates and leaves the minerals, those minerals crystalize.
These are commonly known as a petrified fossils.
What are permineralized fossils or permineralization?
500
The description of rock successions and the interpretation of the layers as means of developing a general geological time scale.
What is stratigraphy?
500
The layering that happens in most sedimentary rocks and igneous rocks that form at the Earth’s surface from lava flows and volcanic deposits.
What is stratification?
500
The three causes of mass extinction scientists have identified.
What are:
Increase of oxygen in the atmosphere
Continental drift-changed the terrain, volcanic activity, global climate change
Meteorite impact-debris fills the sky, plants die, consumers die.
