- Indirect evidence
- Not staightfoward
- Direct evidence
- Analysing an example directly-Physically see it
- Seismic waves
- Vibrations that travel through Earth carrying the energy released during an eq
- Radiation
- The transfer of energy through space
- Convection
- The heat transfer by the movement of currents with in a fluid
- Conduction
- The heat transfer within a material or between materials that are touching
- Viscosity
- The resistance of a liquid to flowing
- Silica
- 50% of magma is silica. More silica is. Ore viscous
- Chemical property
- Property that produces a change in the composition of matter
- Physical prop
- Any characteristic of a substance that can be observed or measured w. Out changung the composition of the substance
- Hawaiian volcanow
- Rounded top quiet eruptions, oozes
- Other volcanoes
- Ones that shaped as a cone it shoots up - high viscosity
- How to map the ocean floor
- Send sonar down to the ocean floor. And record
- Convergergent =
- Continental continental two plates come together
- Convergent un =
- Denser plate subducts (oceanic oceanic) ( contininental oceanic)
- Density
- Mass \ volume-- less dense rises More dense sinks
- What causes convection currents
- Differences in density
- Pangea
- The theory that coninets were all once together
- Earthquake
- Shaking resulting from rock moving under earths surface- caused by moving plates
- Focus
- The place under the earths surface where rock under breaks
- Epicenter
- Point right above the focus
- Primary waves
- Compress and expand fastest , can move through liquid or solid
- Secondary wave
- Move up down, side side, can go through only solids
- Surface waves
- Created by the p ansd s waves 2 kinds love and raleigh
- Love waves
- Move side ways Surface wave Go through liquid and solid
- Rayleigh
- mo Surface wave Liquid and solid
- Fault
- (geology) a crack in the earth's crust resulting from the displacement
- Mercalli scale
- a scale that rates earthquakes according to their intensity and how much damage they cause at a particular place
- Richter scale
- A scale that rates an earthquake's magnitude based on the size of its seismic waves. More for tv
- Moment magnitude scale
- a scale that rates earthquakes by estimating the total energy released by an earthquake.
- Potential energy
- Stored energy
- Elastic rebound
- the sudden release of stored strain in rocks that results in movement along a fault.
- Divergent
- plates come together-deep ocean trench eqs
- transform
- plates slide against shallow eqa
