Summative 1 Flashcards
Elements found in Continental Crust
Si, O, Al, Ca, Na, and K
*Named after Augustus Edward Hough Love. It has a horizontal motion that is transverse to the direction the wave is travelling and is considered to be the fastest surface wave and moves the ground from side to side.
*Cause most damage
*fastest surface wave
Love-wave
Continental Crust that has a density of?
2.7 g/cm^3
7 Minor Plates (CNPJASC)
Carribean
Nazca
Philippine
Juan de Fuca
Arabian
Scotia
Cocos
Layers of the litosphere
(from outside to inside)
1.) Crust
2.) Mantle
3.) Outer core
4.) Inner Core
Oceanic Crust that has a thickness of?
7-10km
*“shear waves”
*secondary wave
S-wave
The area where an earthquake occurs or where the surface slipped
Fault
Type of crust that forms the land
Continental Crust
Consist of crust and the upper mantle
Litosphere
*“compressional waves”
*transmits through gases, liquids, solids
*travels faster than others
*first signal from an earthquake to be felt
P-wave
Scientist who study earthquakes
Seismologist
*The thinnest and outermost layer of the Earth
*Extends 32km
*thickness extends to 72km
Crust
The location below the earth’s surface where the earthquake starts
Hypocenter or Focus
The study of earthquakes
Seismology
Continental Crust that has less dense rocks called?
“granite”
*The shaking and trembling of the Earth’s crust caused by a sudden release of energy.
*It occurs when rocks along a certain fault line suddenly move
Earthquake
Oceanic Crust that has a density of?
2.9 g/cm^3
Types of seismic waves
*Body waves
*Surface waves
The location directly above focus on the surface of the earth
Epicenter
Two types of Crust
Continental Crust
Oceanic Crust
Types of surface waves
*Love-wave
*Rayleigh Wave
*Move in an elliptical motion, producing both vertical and horizontal motions. This moves the ground up and down and side to side in the same direction that the wave is moving. It is named after Lord Rayleigh.
*Moves in elliptical motion
Rayleigh wave
Types of Body Waves
*P-Wave
*S-wave
Continental Crust that has a thickness of?
35-40km
7 Major Plates
Pacific
African
Eurasian
South American
North American
Australian
Antartic
Types of crust that has younger rocks
(less than 200 million years)
Oceanic Crust
Oceanic Crust that has denser rocks called?
“Basalt”
Type of crust that found in ocean floor
Oceanic crust
Energy that is released, carried by vibration
Seismic waves
