Anatomy of Earthquakes
100
Plates that move towards each other and collide. The plate is denser subducts or sinks below the other plate. As they move and scrape against each other, earthquakes occure.
What is convergent oceanic environments?
100
As the rocks along a fault slips into new positions, the rocks release energy in the form of vibrations.
What are seismic waves?
100
The composition of the material through which P waves and S waves travel affects the speed and direction of the waves
What is the earth's interior?
100
At some plateboundaries, there are regions of numerous, closely spaced faults called?
What is fault zones?
100
The location within Earth along a fault in which the first motion of an earthquake occurs.
What is the focus?
200
The can occur between two oceanic plates or between one oceanic pate and one continental playe.
How does convergent oceanic boundaries occur?
200
These travel through the surface of a body rather than through the middle.
What are surface waves?
200
What year did the Croatian scientist discovered the speed of seismic waves increases abrubtly at 30 km beneath the surface of continents?
What is 1909?
200
How do fault zones form?
Fault zones foem at plate boundaries, because of the intense stress that results when the plates separate, collide, subduct, or slide past each other.
200
The point on the Earth's surface directly above the focus
What is the epicenter?
300
They make up the mid-ocean ridges. Plates that are moving away from each other. Earthquakes occur along the ocean ridges.
What are divergent oceanic boundaries?
300
What are the two main categories of waves that occur in body waves?
What are P waves and S waves?
300
What is the three main components that makes up the interior layers of the earth?
What is the crust, mantle, and core?
300
What are locations on the Earth's surface where no body waves from a particular earthquake can be detected?
What are shadow zones?
300
What percentage doces teh focus depths of earthquakes vary of continental earthquakes?
What is 90%
400
earthquakes that occur at locations where two continental plates converge, diverge or move horizontally in opposite directions
What are continental environments?
400
what kind of waves causes rocks to move side to side and perpendicular to the direction in which the waves are traveling?
What are love waves?
400
Earth is composed of five mechanicle layers, what are three of them?
1.) lithosphere 2.) asthenosphere 3.) mesophere 4.) outer core 5.) inner core
400
What causes the speed of a seismic wave to change?
When seismic waves travel through materials of different rigidties, the speed of the waves changes. The waves will also bend and change directions as theyy pass through different materials.
400
Earthquakes that have shallow foci take place within _____ of Earth's surface.
What is 70km??
500
As the continental plates interact, the rock surrounding the boundary experiences stress. The stress causes frequent earthquakes and ___________?
How do mountains form?
500
compression waves are the fastest seimic waves and are always the fastest seimic waves and alwaysn the first waves of an earthquake to be detected.
What are P waves?
500
By studying the speed of seismic waves, scientists are able to locate boundaries between ___________ of Earth.
What is the internal layers?
