- electromagnetic spectrum
- electromagnetic waves arranged from largest to smallest wavelength
- Energy
- anything that can do work or make a change
- What causes earthquakes?
- Slipping and sliding of lithospheric plates
- body waves
- travel through the earth
- p wave
- fastest moving siesmic wave and travels throughsolids liquids and gases
- seismograph
- An instrument for recording the phenomena of earthquakes
- hotspot
- place within tectonic plate directly above rising column of magma
- primary cause for plate movements
- uneven distribution of continents
- surface wave
- slowest most destructive wave
- density formula
- D=m/v
- tsunami
- destructive wave caused by earthquakes in the ocean
- slab pull
- force at subduction boundary that the sinking edge of the seduction plate exerts on the plate
- fault
- a break in the earth's crust where movement occurs
- ridge push
- force exerted by cooling subsiding rock on the spreading lithospheric plates at the mid ocean ridge
- superposition
- the principle that in a series of stratified sedimentary rocks the lowest stratum is the oldest
- aftershocks
- earthquakes of lesser intensity than the mainshock they may occur minutes hours, days, weeks, or years after the first quake.
- Heat
- form of energy that is transferred by a difference in temperature
- focus
- point inside the Earth where an earthquake begins
- where is the ring of fire
- atlantic ocean
- liquefaction
- ground temporarily acts like a liquid
- richter
- measure intensity of earthquake
- crust mantle (lithosphere asthenosphere) outer core inner core
- layers of earth
- deposition
- The process by which sediment settles out of the water or wind that is carrying it.
- Why is Density important?
- Because it affects wind ocean and plate techtonics
- Mineral
- naturally ocurring, inorganic, solid element or compound with a specific chem. comp. and internal crystal structure
- Density
- the amount of matter in a given space mass per unit volume
- 3 types of rock
- igneous metamorphic sedimentary
- crystallization
- the process where atoms are arranged to form a material with a crystal structure
- symmetrical magnetic bands
- earliest sign that the ocean flloor is spreading apart
- s wave
- secondary wave generated by an earthquake and the second to be recorded by a seismograph
- strata
- sedimentary rock that is compressed into layers over time.
- epicenter
- the point on the Earth's surface directly above the focus of an earthquake
- uniformitarianism
- principle that Earth's processes occurring today are similar to those that occurred in the past
- Temperature
- measure of the average kinetic energy of particles that make up a sample of matter
- lithification
- the set of processes transforming sediment into rocks
