Evidence of ancient magnetism found in Earth’s crust
paleomagnetism
how does super heated rock stay solid inside the earth?
Pressure
Why was continental drift theory largely rejected?
No explanation of WHY the continents moved
based on what you know about the earth's crusts. Do you think rock in the continental crust or the oceanic crust is more likely to be older?
Continental
What type of rock makes up the continental crust
granite
Where a compass points
Magnetic north
composed of both the crust and the solid upper mantle
lithosphere
True or False, the oceanic crust is less dense
What type of dinosaur was mentioned in the notes for evidence of the fossil evidence of continental drift theory?
Mesosaurus
what element likely makes up the inner core?
iron and/or nickel
Plates at a ______________ boundary tear apart.
divergent
the crust ______________ on the mantle
floats
any area where a transition from one layer to another is happening gradually; there are multiple throughout the Earth, but the main one is at the bottom of the Asthenosphere
transition zone
An area where oceanic and continental plates converge and oceanic sinks
due to its high density
subduction zone
what layer of the earth fluctuates from solid to liquid?
double prime
What layer of the earth makes up the tectonic plates
lithosphere
how much of the earth is made up by both the crust and the core?
16%
an abrupt shift from one state of matter to another within the Earth, the opposite of a transition zone
discontinuity
