  • Trimester 3 Basketball Review Send up a person from your team If you know the answer grab the ball 1 point for a correct answer and a chance for a bonus point for getting the ball through the hoop from the line!
  • Where do most volcanoes on earth occur?
  • • Along tectonic plate boundaries
  • How does silica affect the viscosity of magma?
  • • More silica means high viscosity…which means it is thick and doesn’t flow as easily
  • Which is younger, layer D or intrusion A?
  • • Intrusion A
  • Based on the seismic readings, which location is nearest to the epicenter of the earthquake?
  • • The seismic station in Oregon is closest
  • What are the three types of sedimentary rock?
  • • Chemical • Clastic • Organic
  • What is the relationship between the size of mineral crystals and the cooling rate of an igneous rock?
  • • The slower the magma cools, the larger the crystals
  • Using the graph, how many years will it take 50% of the C-14 to decay?
  • • 5730x2=11,460 years
  • Why is C-14 not used to date objects over 50000 years old?
  • • After 50000 years, there is not enough parent material left to measure
  • The preserved remains of living organisms are called?
  • • Fossils
  • What is the S-P interval of the seismogram?
  • • About 40 seconds (39ish)
  • If the S-P interval of an earthquake is 47 seconds, how far away was the earthquake?
  • • 460 km
  • The order of seismic waves
  • • Primary (P) • Secondary (S) • Surface (L)
  • The oldest rock layer in the picture
  • • Layer I
  • The youngest rock layer in the picture
  • • Layer H (intrusion)
  • What is the difference between magma and lava?
  • • Magma is molten rock underground, while lava is the same thing on the surface.
  • Predict the silica content of magma with low viscosity.
  • • Low viscosity means that the lava would flow easily. This would mean a low silica content.
  • How are the rocks forming at A different from rocks forming at B?
  • • Rocks at A are intrusive, they cool slowly from magma and would have larger mineral crystals • Rocks at B are extrusive, they cool quickly from lava and have smaller mineral crystals
  • Most earthquake hazards are on the West coast. Why do you thing there is an elevated earthquake risk here?
  • • There must be an active fault in the middle of the continent
  • Fossils that are used to pinpoint ranges of time within rock layers and help scientists to correlate layers of rock are known as _______
  • • Index Fossils
  • Which organism would make the best index fossil?
  • • Organism A would be best…it is only found in 1 layer and is abundant and occurs over a large geographic area
  • The process of sequencing rock layers from oldest to youngest based on their position.
  • • Relative dating
  • The type of volcano with steep sides and alternating layers of lava and ash. It has the most violent eruptions
  • • Composite or Stratovolcano
  • This law/principle states that in undisturbed rock layers, each layer is older than the one above it
  • • Principle of Superposition
  • Portions of rock layers that are missing or altered due to erosion and other disturbances are called _______________
  • • Unconformities
  • The type of volcano made of lava flows with gentle sloping sides
  • • Shield volcano
  • Which environment would be least likely to provide conditions for fossil formation? A dried up lava flow A dried up river bed A dried up tar pit A block of glacial ice
  • • A dried up lava flow
  • The intersection of the 3 circles indicate the _____ of an earthquake
  • • epicenter
  • If you are at a seismic station and there are no Swaves detected from an earthquake, what can you assume about the earthquake’s location in relation to where you are?
  • • The earthquake was on the other side of the Earth. The S-waves were stopped by the liquid outer core.
  • Based on the graphic, a Plinian eruption reads what on the VEI scale?
  • • VEI = 8
  • If Mt. Holly erupts with a VEI of 5, how long would you expect there to be between the next eruption?
  • • 100’s of years
  • Name one way a large volcanic eruption could affect one of the spheres
  • • Geosphere – creates new land, ash adds nutrients to soil • Hydrosphere – ash gets into waterways and sediment builds up, gases get incorporated into water cycle causing acid rain • Atmosphere – gases and ash are transported long distances by wind, temperatures may cool as some gases cause the deflection of sunlight • Biosphere – living things are destroyed by many of the hazards, food chains are disrupted
  • Which type of boundary is responsible for the volcanoes in Hawaii?
  • • Hawaii is not on a boundary but is the result of a hot spot.
  • What was most likely the cause of the events in this picture?
  • • This tsunami was most likely caused by a large earthquake under water
  • What type of metamorphic rock has mineral bands aligned in layers as pictured below?
  • • foliated
  • Which type of metamorphic rock requires the most heat and pressure to form?
  • • Gneiss
  • Using the half life of radioactive elements enables you to determine the ______ age of a rock or fossil.
  • • absolute
