Rock Cycle
The process that carries particles of sediments
What is Erosion
The process where the Earth's lithosphere is in a slow, constant motion, driven by convection currents in the mantle
What is Plate Tectonics?
One of the three "basic" rock type formed under heat and pressure.
What is a Metamorphic rock?
A river today fundamentally acts the same way it did during the time of the dinosaurs
What is the law Uniformitarianism?
Iceland is located on top of these plate boundaries
What is a divergent boundary?
Formed from broken-up fragments of rocks
What are sediments?
The location where two lithospheric plates collide together, one riding over the top of the other.
What is a subduction zone?
A hot material found within the Earths crust that feeds volcanoes
What is magma?
When deep-marine rocks (mudstones and shales) containing marine fossils, are directly overlain, by rocks deposited in aeolian (desert) environments
What is an unconformitie?
San Francisco has one of these plate boundaries running through it
What is a convergent boundary? (If you are smart and also said "Strike-Slip Fault" 300 additional points!)
The process by which solid rock is broken down
What is Wheathering?
Plates that slide past each other
What is a transform plate boundary?
The process by compaction and cementation loose sediment become solid rock
What is lithification?
Forminifera, Trilobites, Ammonites and Corals are all these
What are index fossils?
The process making the bends and folds in the Wasatch Front mountains we can see out our classroom windows (if you are facing that way)
What is deformation?
Liquefying rock
What is melting?
Where two plates collide
What is a convergent plate boundary?
When magma, lava, and mineral-rich fluids becomes solid.
What is crystallization?
Ah-Ah, Pahoehoe and Pillows are all kinds of this rock found all over Hawaii
What is a Lava?
The prossess in which the Colorado river formed the Grand Canyon.
What is erosion?
The accumulation of sediment
What is deposition
Two plates moving away from each other
What is a divergent plate boundary?
Used to age the rocks you're looking at
What is an index fossil?
What happens to a rock at the ultimate end of metamorphism
What is melting
The plate tectonic feature that formed the volcanoes of the Pacific Northwest and Asia
What is a subduction zone?
