100
small pieces of material that comes from rocks or organisms.
What is Sediment?
100
Compared to the ages of other rocks in the layer, what is the relative age of those at the top?
What is the youngest?
100
What are the preserved remains or traces of an organism?
What is a Fossil?
100
These are inorganic, naturally occurring, solids with a crystalline structure and a definite chemical composition
What are Minerals?
200
The source for igneous rock?
What is Magma or lava
200
The process that wears rock down into small pieces
What is Weathering?
200
a fossil that is preserved with little or no change?
What are Preserved remains?
200
It determines the size of minerals
What is the rate of cooling?
300
The size grains would you find in igneous rocks that are cooled above Earth's surface
What is small crystalline structure?
300
The movement of sediment to a new location
What is Erosion?
300
Fossils that were widely distributed over a short period of time
What are index fossils?
300
This explains the existence of tropical fern fossils in Antarctica
What is Continental Drift?
400
The forces are needed to form metamorphic rock
What are Heat and Pressure?
400
The processes that form sedimentary rock?
What are compaction and cementation?
400
These are formed when minerals replace all or part of an organism
What are Petrified Fossils?
400
The processes that form sediment, leading to sedimentary rock formation.
What are erosion and deposition?
500
This is required for the formation of ALL sedimentary rock
What is deposition?
500
The age of a rock compared to the ages of other rocks
What is the relative age?
500
States that the rocks and fossils in the bottom layers of sedimentary rock are older than those at the top
What is the Law of Superposition?
500
The best way to compare rock layers in different locations
What is look at the fossils in the rock?
