Drags plate as mantle move beneath tectonic plate
Mantle Convection
Heat transfer where dense materials sink and less dense material rise
Convection
As the slab of plates sink its weight pull the rest of the plates behind
Slab Pull
Pushes away older part of lithosphere that lies far from ridge
Ridge Push
Area in mantle where rocks melt
Hot Spot
Magma deep inside mantle
Mantle Plume
Most active volcano among hawaii ridge emperor seamout chain
Mt. Kilauea
GPS
Global Positioning System
Moves at rate 6.8 cm a year
Indo- Australian plate
Moves at slow rates about 2.5 cm a year
North american plates
Energy that humans use everyday
Electromagnetic radiaton
Accelerates charged particles and produce magnetic and electric fields
Electromagnetic Radiation
2 types of wave
- Mechanical wave
- Electromagnetic wave
Highest point of transverse wave
Crest
Lowest point of wave
Trough
Maximum vertical displacement of wave , distance between 2 crest or trough (ƴ)
Wavelength
Once complete pattern of wave
Wave cycle
He studied electromagnetic waves
James Clerk Maxwell (1860)
Speed of light
3.0x10⁸m/s
Needs a medium to move
Mechanical
Can travel through space
Electromagnetic waves
From crest to resting point
Amplitude
Crest to trough
Wave height
Wavelength is expressed in?
Meters
