100
capital of Oregon
What is Salem
200
Capital of Idaho
What is Boise
200
name of super continent
What is pangea
200
device used to map surface of the ocean
What is sonar
200
the measure of how much mass there is in a volume of substance
What is density
200
3 plate boundaries
What is convergent, divergent, and transform
300
layer that breaks apart to form plates
What is the lithosphere
300
Why his theory was rejected
What is could not prove force that moved the plates (convection currents in the mantle)
300
2 types of evidence geologists use to make inferences about the Earth's interior
What is rock samples and seismic waves
300
Capital of washington
What is Olympia
300
feature caused by a convergent boundary
What is sea trench and/or mountain range
400
difference between inner and outer core
What is outer core is liquid
400
Capital of California
What is Sacramento
400
evidence that supported Hess' theory of Sea-Floor Spreading (3 examples)
What is magnetic stripes on ocean floor, older crust farthest away from mid-ocean ridge, magma plumes (molten material)
400
the process by which the ocean floor sinks into the mantle
What is subduction
400
rock that mostly makes up oceanic crust and rock that makes up continental rock
What is basalt (oceanic) and granite (continental)
500
relationship between depth and pressure as relevant to the layers of the Earth
What is as depth increases, so does pressure
500
Wegener's evidence to support his theory (list 3)
What is sea-floor spreading, continents fitting together like a puzzle, fossils, climate change, features like coal mines matching
500
Capital of Monatana
What is Helena
500
What causes the plates to move and what is the heat source
What is convection currents in the mantle and the heat is from the core and the mantle itself
500
2 features caused by a divergent plate boundary
What is mid-ocean ridge and a rift valley
