This type of rock forms from cooled magma or lava.
What is igneous rock?
This process happens when sediments are dropped and settle in a new location.
What is deposition?
Fossils are most commonly found in this type of rock.
What is sedimentary rock?
This law states that deeper rock layers are older than layers above them.
What is the Law of Superposition?
This fossil fuel forms mainly from ancient plants.
What is coal?
This type of rock forms from compacted and cemented sediments.
What is sedimentary rock?
This process happens when magma cools and forms crystals, often creating igneous rock.
What is crystallization?
This process happens when sediments bury dead organisms over time.
What is fossilization?
The oldest rock layers are found in this position.
What is at the bottom?
These fossil fuels form from ancient marine organisms.
What are oil and natural gas?
This type of rock forms when existing rock is changed by heat and pressure.
What is metamorphic rock?
This process turns loose sediments into solid rock, often creating sedimentary rock.
What is lithification?
This process occurs when sediments bury dead organisms over time, and minerals fill in or replace the spaces in the organism’s remains.
What is fossilization?
If Layer A is below Layer B, and Layer B is below Layer C, which is oldest?
What is Layer A?
This is one major use of fossil fuels.
What is energy production (electricity, fuel for cars, etc.)?
This process breaks rocks into smaller pieces.
What is weathering?
This is a break or crack in Earth’s crust where movement can occur.
What is a fault line?
A type of fossil formed when an organism leaves an imprint or outline in sediment that later hardens into rock.
What is an impression?
This type of age tells whether something is older or younger compared to something else, but not the exact number of years.
What is relative age?
Fossil fuels are considered ___, because they take millions of years to form and cannot be replenished quickly.
What is non-renewable?
This process moves sediments from one location to another.
What is erosion?
This occurs when magma pushes into existing rock layers but cools underground.
What is a magma intrusion?
This type of fossil lived for a short period of time and is used to determine the relative age of rock layers and other fossils.
What is an index fossil?
Identical fossils are found in the same type of rock and in two very different locations (e.g., The Grand Canyon and The Sierra Nevada Mountains). What can scientists infer about the ages of the these rock layers?
What is... they are the same age!
Burning fossil fuels can cause this major environmental problems like...
