Geology
These are the 3 types of rocks
What are igneous, sedimentary, and metamorphic?
Fossils that were found worldwide, during a short period of time, are this type of relative dating method
What are index fossils?
This is the study of fossils
What is Paleontology?
Two plate boundaries moving away from each other, forming new lithosphere, are this type of boundary
What is divergent?
The age of the earth is approximately
What is 4-5 billion years old?
This important law states that older rock will be found under newer rock layers.
What is the Law of Superposition?
This type of fossil can be found in amber
What is preserved or true form?
Two plate boundaries moving towards each other, causing destruction of crust or the formation of mountains are called this
What is convergent boundary?
This type of rock is formed by layers of sand and mud pressed down over time
What is sedimentary?
This relative dating method gives scientists information about the earth's climate over time
What are ice cores?
This type of fossil gives scientists clues as to how an organism lived
What is trace fossil?
This supercontinent was once all the land on earth joined together in one main mass
What is Pangaea?
Finding an intrusion of igneous rock embedded in sedimentary layers is most likely due to this
What is volcanic activity?
If a trilobite is found in a layer of rock above igneous rock, you could assume this
What is the trilobite lived after a volcanic intrusion
This isotope is primarily used to calculate the age of rocks and fossils
What is carbon 14?
When one plate converges towards another and goes under that plate, is causes crust to be destroyed and is called this
What is subduction?
All metamorphic rocks were at one time either
What are sedimentary and igneous?
This was created based on dates from major events in earth's history
What is The Geologic Time Scale?
The type of fossil created when an imprint is filled in with sediment and hardened over a long period of time
What is cast?
When one plate drops straight down, leaving a shear face, it is called this type of fault
What is dip-slip?
