  1. Core Sample Sheet Deposition Rate is 1mm = 1000 years Name: _____________ hr ____ Core #1 Core #2 1 1 2 1 1 1 2 2 1 Cobble – made of rock particles 64 – 256 mm 1 1 2 2 1 3 3 2 Granule – made of rock particles 2-4 mm Very Course Sand – made of rock particles 1-2 mm Siliceous Ooze – made of fine silicon dioxide Calcareous Ooze – made of microscopic calcium carbonate Mud – fine clay sized

  2. Which core sample is from below 4500m? How can you tell? • Which sample is taken from closer to land? How can you tell? (this should be a different reason than from question 1) 3. Give the years to from the layers: Core 1 Core 2 Mud 1 = _____________________ Siliceous Ooze 1 = ___________________ Calcareous Ooze 1 = __________________ Mud 1 = _____________________ Mud 2 = _____________________ Siliceous Ooze 2 = ____________________ Granule 1 = _____________________ Mud 2 = _____________________ Very Course Sand 1 = __________________ Very Course Sand = ___________________ Siliceous Ooze 1 = ______________________ Mud 3 = ____________________ Granule 2 = __________________________ Siliceous Ooze 3 = ____________________ Calcareous Ooze 2 = _____________________ Very Course Sand 2 = _________________ Cobble 1 = _____________________________ 5. How many years to form all of core # 1? 6. Which are the largest particles? 7. Would the largest particles settle out first or would they be carried out the farthest to sea? 8. Out of both Core samples, which individual layer took the most time to form? 9. Out of both Core samples, which individual layer took the least time to form? P.345-346 10. List the 3 types of Seafloor sediments and describe what each consists of. 1. __________________ ________________________________________________ 2. __________________ ________________________________________________ 3. __________________ ________________________________________________ 11. List 4 common types of Hydrogenous sediments and give a brief description of each 1. __________________ ________________________________________________ 2. __________________ ________________________________________________ 3. __________________ ________________________________________________ 4. __________________ ________________________________________________
