Plate Tectonics
Places where plates meet are called
what are plate boundaries
What are the 3 kinds of faults
these types of waves happen beneath the earth's surface and are divided into P and S waves
What are Body Waves
this earthquake scale measures destruction and is based on man's observation
What is the Mercalli scale
A deep break or crack in the earth's surface alone which rocks can move
What is a fault
Which type of fault movement do creation scientist think God used to create mountains, like the Himalayan mountains in Asia
What is reverse faults
this type of fault happens when rocks move horizontally past each other.
What are strike-slip faults
These waves are slow moving and are very destructive during an earthquake
What are surface waves
this earthquake scale measures the magnitude of the earthquake
The richter scale
the strength of the seismic waves of an earthquake is the what?
What is magnitude
What are the parts of the earth (we talked about 4)
crust, mantle, outer core, inner core
What do scientist call a normal fault that occurs under the ocean?
what is sea-floor spreading
What are the 2 types of surface waves?
Love and Rayleigh Waves
What machine do scientist use to detect, time and measure the movement of the earth?
What are seisomgraphs
What is the epicenter
In what 3 ways can plates move against each other?
Collide, separate, and slide
A thrust fault or __________ fault occurs where rocks push together until they force a section of rock upward
What is a reverse fault
True/False - P waves are fast moving and can go through both solids and liquids
True
Which scale would be better fight to measure an earthquake in an UNPOPULATED area
What is the Richter scale
A scientist who studies movements of the earth
What is a seismologist
Some scientists believe that at one time the earth could have been a single large landmass. What did they call it?
What is Pangaea
This fault occurs at plate boundaries and as rocks move apart, a section of the rock my fall creating a separation between the plates
What is a normal fault
Which waves can only move through solids?
S waves
A huge wave resulting from an earthquake, landslide, or volcano that occurs under or near the ocean
what is a tsunami
The idea that the earth's crust is made up of m moving plates is called
What is the theory of plate tectonics
