A famous example of a transform boundary in the U.S. is
As depth beneath Earth's surface increases, temperature and pressure
approach zero
both decrease
both increase
What is the correct order (starting from the surface) of Earth's layers?
mantle, outer core, inner core, crust
crust, mantle, outer core, inner core
crust, outer core, inner core, mantle
Earth's mantle is
a layer of molten metal
a layer of hot rock
a layer of rock that forms Earth's outer skin
Heat is transferred within a fluid by
conduction
convection currents
radiation
When the heat source is removed from a fluid, convection currents in the fluid will
speed up
change direction
eventually stop
What is Pangaea?
the name of a German scientist
another name for continental drift
the name of the supercontinent that existed millions of years ago
The mid-ocean ridge is a
convergent boundary
divergent boundary
transform boundary
In the process of sea-floor spreading, where does molten material rise from the mantle and erupt?
along the edges of all the continent
in deep-ocean trenches
along the mid-ocean ridge
The process by which the ocean floor sinks through a deep-ocean trench and back into the mantle is known as
continental drift
subduction
convection
Most geologists think that the movement of Earth's plates is caused by
convection currents in the asthenosphere
gravity
subduction
The geological theory that states that pieces of Earth's lithosphere are in constant, slow motion is the theory of
plate tectonics
sea-floor spreading
subduction
A place where two plates slip past each other, moving in opposite directions, is known as a
transform boundary
convergent boundary
divergent boundary
The place where two plates come together is known as a
transform boundary
divergent boundary
convergent boundary
