300
What is the term when a older rock cross cut through younger rock?
Intrusion
300
This law applies to rocks in the rock cycle
They are never destroyed, but are recycled.
300
What are the two types of igneous rock?
intrusive and extrusive.
400
What are two principles of relative dating?
The principles of superposition and X-cutting relationships
400
What happens when two continental plates slide past each other and what type of boundary is this?
earthquakes will occur and it's a transform boundary
400
What is the ring of fire?
A large ring around the Pacific coastline where active volcanoes and earthquakes occur. Johnny Cash wrote and sang this song.
400
What are the 5 transformations that rocks go through.
melting, cooling. heat and pressure, compaction and cementation, wearthering and erosion
400
What is radiometric dating?
Absolute dating of igneous rocks using isotopes
500
What conditions need to be present for a plant or animal to become a fossil?
Remains of organism protected from decomposition, trapped in sediment and compaction to form fossils.
500
What occurs where a ocean crust pulls away from another oceanic crust and what type of boundary is this?
Mid ocean ridge forms and it's a divergent boundary
500
This force that's responsible for the movement of the plates. It's a type of oven?
Convection.
500
What is the only transformation that sediment has?
Compacting and cementing of sediment.
500
What happens when two continental plates diverge?
A rift valley is formed.
