Question	Answer
Holes drilled several kilometers into Earth's crust provide direct evidence about Earth's interior in the form of ?	rock samples
Geologists obtain indirect evidence about Earth's interior by?	recording and studying seismic waves
What is the correct order of Earth's layers?	crust, mantle, outer core, inner core
Earth's inner core is made of what?	a dense ball of solid metal
When you touch a hot pot or pan, energy moves from the pot to your hand. This is called?	heat transfer
The transfer of energy through empty space is called?	radiation
Heat transfer within a fluid takes place by?	convection currents
What is Pangaea/	the name of the supercontinent that existed millions of years ago
Which type of evidence was NOT used by Alfred Wegener to support his continental drift hypotheses?	evidence from human remains
Most geologist rejected Alfred Wegener's idea of continental drift because?	Wegener could not identify a force that could move the continents.
What technology did scientists use in the mid-1900s to map the mid-ocean ridge?	sonar
In sea-floor spreading, molten material rises from the mantle and erupts	along mid-ocean ridges
How did scientists discover that rocks farther away from the mid-ocean ridge were older that those near it?	by determining the age of the rock samples obtained by drilling on the sea floor
The process by which the ocean floor sinks beneath a deep-ocean trench and back into the mantle is known as?	subduction
old oceanic crust is more dense than new oceanic crust because it is	cool
Most geologists think that the movement of Earth's plates is caused by	convection currents in the mantle
A place where two plates slip past each other, moving in opposite directions, is known as a	transform boundary
a rift valley forms at a	divergent plate boundary
Using data from seismic waves, geologist have learned that Earth's interior is made up of several	layers
Earth's magnetic field results from movements in the	outer core
Scientists think that convection currents flow in Earth's	mantle
A collision between two pieces of continental crust at a converging boundary produces a	mountain range
Any trace of an ancient organism that has been preserved in rock is called a	fossil
mid -ocean ridges are	found in all of Earth's ocean's
The place where two plates come together is known as a	convergent boundary
When you touch a hot plate, the heat transfer of heat from the plate to your hand is called	conduction
traces of ancient organisms preserved in rock	fossils
continually adds new crust to the ocean floor along both sides of the mid-ocean ridge	sea-floor spreading
subduction occurs where the oceanic crust bends down toward the mantle at a	deep-ocean trench
formation of volcanoes and mountain ranges can be explained by the theory of	plate tectonics
The inner core is surrounded by the hot, molten metal layer called?	outer core
asthenosphere is in what layer of the Earth	mantle
which layer of Earth is made up of part crust and part mantle	lithosphere
