Earthquakes/Volcanoes
This rock would be most abundant in Hawaii.
What is igneous rock?
If four sedimentary rock layers are cut by an igneous rock intrusion, this best describes the relative age of the igneous rock intrusion in comparison to the ages of the four sedimentary rock layers.
What is the igneous rock intrusion is younger than sedimentary rock layers it cuts across?
This is most likely to provide information about the Earth’s past climates.
What are ice core samples?
This natural occurrence is the direct result of tectonic plate movement.
What is an earthquake?
This chemical compound is present in an ice core sample.
What is carbon dioxide?
This type of rock forms by cooling and hardening of molten rocks from inside the Earth.
What are igneous rocks?
Scientists are most likely to use these to estimate the age of earth.
What are rock layers?
This is the most accurate method scientists can use to estimate earth's age.
What is radioactive dating?
Rock layers with seashells are found on top of a mountain much higher than sea level. This process most likely caused this.
What is deposition?
This is the most likely reason scientists would want to analyze the air trapped in an ice core.
What is to learn how the atmosphere changed over time?
This is the abundance of earthquakes & volcanoes surrounding the Pacific ocean.
What is the ring of fire?
This method of determining relative age of rock layers can best be used.
What is the law of superposition?
This type of rock forms by hardening and cementing of layers of sediment.
What is sedimentary rock?
This scientist is credited with the idea of continental drift.
Who is Alfred Wegener?
Corals found in rock layers worldwide would be an example of this.
What are index fossils?
This is a molten rock from the Earth’s interior that squeezes into existing rock and cools.
What is an intrusion?
Scientists studying a geologic site found tropical plant fossils in a lower rock layer and fossils of woolly mammoths, also called tundra mammoths, above the layer. This is the most likely conclusion for why the tropical plant became extinct.
What is the tropical plants became extinct due to global climate change?
Uranium is a mildly radioactive type of substance that breaks down at this pace which can't be altered by temperature or pressure.
What is a slow and steady pace?
The discovery of the theory of continental drift led to the subsequent discovery of this theory.
What is plate tectonics?
The layer of sedimentary rock that would have the oldest fossils.
What is the lowest layer with fossils?
This type of circumstances have usually caused the extinction of plants and animals.
What are environmental changes?
This is the role faults play in the Law of Superposition.
What is faults are younger than the layers they cut through?
This scale describes the history of Earth from when it was formed.
What is the geologic time scale?
These are the 3 plate boundaries and how they move in relation to each other.
What are convergent (towards), divergent (away), transform (slide past)
A picture shows fossil samples found in four layers of sedimentary rock. This is concluded about the area they were found if all the fossils are ocean dwelling creatures.
What is that it was once covered by water?
