types of seismic waves
surface waves body waves
23
twotypes of body waves
primary and secondary waves
24
also stands shear or shake waves
s-waves or secondary waves
24
a longitudinal wave or compressional waves due to particle compression during their transport
primary waves or p-waves
25
also stands for push and pull waves
primary waves or p-waves
26
they are transverse waves shake particles at right angles to the waves direction of travel
secondary waves
27
travelling only to the crust
`surace waves
28
this wave is similar to how waves prpagate the waves are descriptively called ground roll
rayleigh waves
29
2 types of surface waves
love waves and rayleigh waves
30
named after A.E.H Love
love waves
31
this wave is somewhat similar to s-waves, travel by a transverse motion of particles that is parallel to the ground surface
love waves
32
rayleigh waves was named after who?
Lord Rayleigh
33
is the study of earthquakes and seismic waves that moves through and around the earth
seismology
34
is a scientist who studies earthquakes and seismic waves
seismologist
35
is an instrument used to detect and record seismic waves
seismograph or seismometer
36
sound that travels through soft tissue and fluids
ultrasound
37
is an area of the earths surface where sismographs cannot detect earthquakes after it seismic waves had pass through the earth
seismic shadow zone
38
is the most destructive seismic waves
surface waves
39
all earth
pangea
40
all water
panthalassa
41
laurasia
gondwanaland
41
theories of the movement of the plates
continental drift theory seafloor spreading theory plate tectonics theory
42
the two scientists who used visial or drawing in seafloor spreading theory
harry hesc robert dietz
43
SONAR
sound navigation and raging
44
they didnt study it its just the combination of alfred, robert and harry
plate tectonics theory
45
a german meteorologist and geophysicist changed the worlds perspective of the earth
alfred wegener
45
greek word for pangea
all earth
46
stated that continents were all connected at one point in earths history
the continental drift theory
46
was a woody, seed bearing shrub or tree
glossopteris
47
it forms a single largest mountain chain in the world
mid-ocean ridges
48
is a continous process because forces cause opposite sides of the mid-ocean ridge to constantly move apart
seafloor spreading
49
refers ti change in the earths magnetic field
alternating magnetic polarity
49
who proposed convectional current theory
arthur holmes
50
laws of motion
law of inertia law of acceleration law of interaction
51
an object will not change its motion unless a force acts on it.
law of inertia
52
the force on an object is equal to its mass times its acceleration
law of acceleration
53
when two objects interact, they apply forces to each other of equal magnitude and opposite direction
law of interaction
54
changes in long term averages of daily weather
climate change
55
average of weather over time and space
climate
56
floods
el nino
57
drier or warmer
la nina
58
stable subatomic particle
electrons
59
moving
motion
60
any influence that can produce a change in the speed or direction of the motion of a subject
force
60
rate of change of distance
speed
61
rate of change of displacemnt
velocity
62
a muscular funnel that extends from theposterior end of the nasal cavity to thesuperior end of the esophagus and larynx
pharynx
63
connects the larynx to the bronchi andallows air to pass through the neck and intothe thorax
trachea
64
into the right lung before branching off into smaller secondary bronch
left pulmonary bronchus
65
large, spongy organs found in the thoraxlateral to the heart and superior to thediaphragm
right lung
66
inside of the nose
nasal cavity
67
muscles found beneath the lungs that aid thebreathing process
diaphragm
68
two external openings of the nasal cavity; alsoreferred to as nostrils
external nares
69
also known as the voice box
larynx
70
This blood component serves as the soldier ofthe body which fights off foreign diseases
white blood cells
70
71
runs into the left lung before branching off into smaller secondary bronchi
left pulmonary bronchus
72
This blood component carries oxygen andcarbon dioxid
red blood cells
73
This blood component takes part in bloodclotting.
platelets
73
blood flow between the heart and body tissues
systemic circulation
74
This blood component makes up most of theblood and is composed mainly of water
plasma
75
flow of blood between the heart and the lungs
pulmonary circulation
