Earth's Interior
Rocks drilled from deep inside earth allow geologist to make inferences about conditions.
What is Direct Evidence from rock samples?
Heat transferred by direct contact of particles on matter
What is conduction?
The process of continually adding new crust to the ocean floor along both sides of the mid-ocean ridge
What is sea-floor spreading?
The geological theory of this states that pieces of Earth's lithosphere are in constant, slow motion
What is plate tectonics?
crust, mantle, outer core, inner core
What is the Earth's layers?
Made mostly from metals iron and nickel
What is the core?
Measure of how much mass there is in a volume of a substance
What is density?
The name of the supercontinent that existed millions of years ago
What is Pangaea?
A place where two plates slip past each other, moving in opposite directions, is known as
What is transfer boundary?
A collision between two pieces of continental crust at a converging boundary produces
What 9os mountain range?
Uppermost part of the mantle and the crust for a ridge layer about 100 kilometers thick
What is the lithosphere?
The transfer of heat by direct contact of particles of matter
What is conduction?
Wegener could not identify a force that could move the continents
Why was Wegener's theory rejected?
A rift valley forms at a
What is divergent plate boundary?
Scientists think that convection currents flow in Earth's
What is mantle?
Consists mostly of basalt
What is the oceanic crust?
The transfer of energy through empty space
What is radiation?
Pillow-shaped rocks formed by the rapid hardening of molten material
What is mid-ocean ridge?
When two plates of oceanic crust collide or when an oceanic plate collides with a continental plate
Using data from seismic waves, geologist have learned that Earth's interior is made up of several
What is layers?
Movement of liquid outer core creates this
What is a magnetic field?
Heat transferred within fluid takes place by
What is Convection Currents?
The process by which the ocean floor sinks beneath a deep-ocean trench and back into mantle
What is subduction?
The place where tow plates come together
What is convergent boundary?
Subduction occurs where oceanic crust bends down towards the mantle an a
What is deep-open trench?
