Week Seven Oceanography

1. 1Professor David Fox gave multiple lines of evidence for Neoproterozoic glaciations. Which is NOT one of them?

   1. APoorly sorted sedimentary rocks called tillite
   2. BOxygen isotope composition of seawater that reflects the size of continental ice
   3. CStriated pebbles in glacial deposits
   4. DDropstones in proglacial marine sediments
   5. ENone of the above
2. 2Rogue waves are unexpectedly large waves that form as a result of destructive interference of smaller waves

   1. AVerdadeiro
   2. BFalso
3. 3Which is true about energy in surface ocean waves?

   1. AAs waves travel, they carry energy
   2. BThe atmosphere transfers energy to the oceans as the atmosphere creates waves in the oceans
   3. CUltimately wave energy is dissipated as heat, which is radiated out to space
   4. DAll of the above
   5. ENone of the above
4. 4Which is false about how waves grow and break?

   1. AWave amplitude increases as waves are slowed by bottom friction and get compressed
   2. BWaves break when their amplitude and steepness exceed what water can sustain
   3. CIf water had less cohesion, for example to weaker hydrogen bonds, waves would likely break more easily
   4. DAll of the above
   5. ENone of the above
5. 5Which is true about how waves interact with the beach?

   1. AWaves travel faster over shallower waters than over deeper waters
   2. BWaves that approach the beach at an oblique angle produce longshore currents
   3. CLongshore currents do not transport sediments along the beach
   4. DRip currents are slow movement of water from the sea to the beach
   5. ENone of the above
6. 6Which is false about surface water wave speed?

   1. ACelerity refers to the speed of wave propagation
   2. BIn deep waters, longer waves travel faster than shorter waves
   3. CIn deep waters, waves with longer periods travel faster than those with shorter periods
   4. DCelerity of shallow water waves depends on the water depth
   5. ENone of the above
7. 7The restoring force of a wave traveling in a string held between two students is:

   1. AGravity
   2. BTension in the string
   3. CWeight of the string
   4. DAtmospheric pressure
   5. ENone of the above
8. 8Tsunamis become dangerous as they approach the coast

   1. AVerdadeiro
   2. BFalso
