Plate Boundaries Vs. Plate Tectonics Flashcards
it consists of a seismometer for sensing ground motion, a clock for determining time.
Seismic station
can move through solid rock and fluids, like water or the liquid layers of the earth
Primary Wave
fastest kind of body wave
Primary Wave
Two kinds of Seismic waves
Body waves, Surface Waves
Two types of body waves
Primary Wave, Secondary Wave.
It pushes and pulls the rock it moves through just like sound waves
push and pull the air (body)
Primary Wave
This wave moves rock up and down, or side-to-side (body)
Secondary Wave.
Slower kind of body wave
Secondary wave.
This wave can only move through solid rock
Secondary wave.
The two kinds of surface waves
Love wave, Rayleigh wave.
A british mathematician who
worked out the mathematical model for
the love wave
Augustus Edward
Hough Love.
The fastest kind of surface wave.
Love wave.
Surface wave that moves the ground side to side, similar to a snake.
Love wave
Who mathematically predicted the existence of the Rayleigh wave?
John William Strutt, Lord Rayleigh (Rayleigh wave)
rolls along the ground just like a wave rolls across a lake or an ocean
Rayleigh Wave
scientific theory that explains how
major landforms are created as a result of Earth’s subterranean movements.
Plate Tectonics
it moves the ground up and down, and side-to-side in the same direction that the wave is moving. (surface)
Rayleigh Wave
When was the Plate Tectonics theory solidified?
1960’s
Father of “Plate Tectonic Theory”
Alfred Lothar Wegener
Is the upper mechanical layer of the Earth that is divided into tectonic plates that constantly move
Lithosphere
Moves around 1-3 inches per year
Lithosphere
It is where tectonic plates meet or interact. Most geologically active places on earth
Plate Boundaries
Plates that move away from each other. It is generally situated on the
ocean floor along the crests of mid-oceanic ridges
Divergent Plate Boundary
Where lithospheric plates move toward each other.
Convergent Plate Boundary.
Where plates move horizontally past each other. (plate boundary)
Transform Plate Boundary
more destructive type of body wave
S waves
