The relative age of a rock is
its age compared with the ages of other rocks
less than the age of the fossils the rock contains
the number of years since the rock formed
its age based on how much carbon-14 the rock contains
Originally, the geologic time scale placed Earth's rocks ni order by
radioactive dates.
relative age.
composition.
decades and centuries.
Stress that pushes a mass of rock in two opposite directions is called
shearing.
tension.
compression.
deformation.
Which of the following can cause damage days or months after a large earthquake?
the arrival of surface waves
convection
a tsunami
an aftershock
In a normal fault, the part of the fault that lies below the other part is called the
hanging wall.
reverse fault.
footwall
anticline
The point beneath Earth’s surface where rock breaks under stress and triggers an earthquake is called the
syncline.
footwall.
epicenter.
focus.
The rating system that estimates the total energy released by an earthquake is called
Richter scale.
moment magnitude scale.
mechanical seismograph scale.
Mercalli scale.
S waves are also known as
primary waves.
secondary waves.
surface waves.
focus waves.
Compared to P waves and S waves, surface waves move
faster
slower
at the same rate
farther from the epicenter
According to Wegener’s hypothesis of continental drift,
Earth's surface is made up of seven major landmasses.
the continents do not move.
Earth is slowly cooling and shrinking.
the continents were once joined together in a single landmass.
What is Pangaea?
the name of a German scientist
the name of the supercontinent that existed millions of years ago
another name for continental drift
the name of an ancient fossil
In sea-floor spreading, molten material rises from the mantle and erupts
along the edges of all the continents.
along mid-ocean ridges.
in deep-ocean trenches.
at the north and south poles.
Most geologists think that the movement of Earth’s plates is caused by
conduction.
earthquakes.
convection currents in the mantle.
Earth's magnetic field.
The geological theory that states that pieces of Earth's lithosphere are in constant, slow motion is the theory of
subduction.
plate tectonics.
deep-ocean trenches.
sea-floor spreading.
A place where two plates slip past each other, moving in opposite directions, is known as a
transform boundary.
divergent boundary.
convergent boundary.
subduction boundary.
A collision between two pieces of continental crust at a converging boundary produces a
mid-ocean ridge
deep-ocean trench.
rift valley.
mountain range.
How did scientists discover that rocks farther away from the mid-ocean ridge were older than those near it?
by observing eruptions of molten material on the sea floor
by mapping rocks on the sea floor using sonar
by determining the age of rock samples obtained by drilling on the sea floor
by measuring how fast sea-floor spreading occurs.
The place where two plates come together is known as a
transform boundary
divergent boundary
convergent boundary
rift valley.
