| Speed | The distance an object travels in a period of time
🗑
|
||||
| Theory of Plate Tectonics | Earth's plates move slowly in various directions through convection energy transfer in the mantle (some push away, some push together)
🗑
|
||||
| Plate | Large pieces of lithosphere that are in constant motion
🗑
|
||||
| Lithosphere | The rocky outer shell of Earth includes the crust and upper mantle (brittle and rigid) more solid
🗑
|
||||
| Asthenosphere | Lies below the lithosphere with a low density and very ductile much hotter (plastic and flowing) more liquid
🗑
|
||||
| Plate Boundary | Region where two tectonic plates meet
🗑
|
||||
| Transform | Plates slide side by side
🗑
|
||||
| Convergent | Plates move towards each other
🗑
|
||||
| Oceanic-Continental Convergent | More dense and subducts the continented plate creating and ocean trench and a chain of volcanoes
🗑
|
||||
| Continental-Continental Convergent | Two plates collide creating a mountain rage
🗑
|
||||
| Oceanic-Oceanic Convergent | Collide to create volcanoes and islands in between
🗑
|
||||
| Divergent | Plates move away from each other
🗑
|
||||
| Oceanic-Continental Divergent | Forms mid-oceanic ridges leading to underwater volcanoes give rise to volcanic islands
🗑
|
||||
| Continental-Continental Divergent | Produce rift valleys eventually creating oceanic plates
🗑
|
||||
| Acceleration | Rate of change, direction, or both
🗑
|
||||
| Forces | Pushes or pulls
(a combination is a twist
🗑
|
||||
| Kinetic Energy | A force acts on a stationary object and causes motion
🗑
|
||||
| Force Diagram | Show the forces acting on an object and whether they are balanced or unbalanced
🗑
|
||||
| Newton's 1st Law of Motion | An object in motion remains in motion and a object at rest remains at rest unless acted on an unbalanced force
🗑
|
||||
| Newton's 2nd Law of Motion | F=MA
🗑
|
||||
| Weight | A force. Measured in Newton's (N)
🗑
|
||||
| Friction | A force oppose motion between 2 surfaces that are touching
🗑
|
||||
| Newton's 3rd Law of Motion | For every action there is an equal and opposite reaction
🗑
|
||||
| Waves | A disturbance that travels through a medium from one location to another offering transferring energy
🗑
|
||||
| Transverse | Causes vibration in the medium in perpendicular direction to its own motion
🗑
|
||||
| Longitudinal | Have vibrations along or parallel to their direction of travels
🗑
|
||||
| Wavelength | The distance between adjacent crests, measured in meters
🗑
|
||||
| Period | The time it takes for a complete to pass a given point, measured in seconds
🗑
|
||||
| Frequency | the # of complete waves pass a point in one second measured in Hertz (Hz)
🗑
|
||||
| Crest | The highest part of a wave
🗑
|
||||
| Amplitude | How far the medium waves when the wave passes through
🗑
|
||||
| Trough | The lowest point in a wave
🗑
|
||||
| Refraction | The change in direction of a wave due to a change in its speed
🗑
|
||||
| Visible Light | ROY G BIV (red has a longer wavelength)
🗑
|
||||
| Seismic Waves | Carry energy from an earthquake away from the focus, through Earth's interior and across the surface
🗑
|
||||
| Primary(P)Waves | Can travel through all states of matter through compressions and rarefactions much like an accordion
🗑
|
||||
| Secondary(S)Waves | Cannot move through liquids; move back and forth and up and down (transverse wave)
🗑
