1 Earth Science 11 Learning Guide Unit 8 Name: 8-1 Ocean Properties 1. Complete the following paragraph about the ocean and ocean water with the following words: thousand chloride 70% salinity water sodium Mariana Trench parts ions The Earth s ocean covers of the Earth s surface. The deepest part of the ocean is at the and is over meters deep. Ocean water is actually various mixed with. The amount of ions dissolved in water is called which is measured as per. The two most common ion found in seawater are ion and ion. 2. This diagram shows two containers with two samples of seawater. The black dots represent ions dissolved in the water. A. Compare each container and determine which shows low salinity and which shows high salinity. Write Low or High under the correct container. B. For each statement below put A in the space if it refers to Container A or B if it refers to Container B. Sample is from the tropics Sample is from where a river meets the sea Sample is from the Vancouver in the winter time. Sample is from the Artic Ocean Sample is from Vancouver in the summer time.

2 3. Label the following profile of the ocean with the terms photic zone, thermocline, and deep water For each statement below put P if it refers to the photic zone, T for thermocline, and D for Deep: Has a relatively constant temperature Shows a slow change in temperature. Temperature drops quickly. Supports life Also called the mixed layer Has the most exposure to sunlight 4. Consider Profile A and Profile B in the above diagram: Vancouver during the summer is most likely shown in Profile. Water from the equator is most likely shown in Profile. Vancouver in the winter is most likely shown in Profile. Sketch what the profile from the Arctic Ocean would look like in the last profile. ES11LG-Unit 8 Page 2 of 9

3 8-2 Ocean Currents 5. Complete this charts of ocean currents with the following terms: warm salinity cold gyra temperature surface upwelling 6. What causes ocean currents? 7. This table shows the profile of three bodies of water. The oval represents the path of the current. Base on the information provided, put arrow heads on the oval to show the direction of current flow. ES11LG-Unit 8 Page 3 of 9

4 8. Referring to the diagram in the previous question, Kelly said Profile B is most likely from a tropical body of water like the Mediterranean Sea. Explain why Kelly is correct or incorrect. 9. Which profile from question 7 is mostly likely from the North Atlantic? Explain why. 10. Add comments, arrows etc to show how the winds create upwelling or the vertical movement of water current. 11. What role does upwelling play in maintaining the biosphere? ES11LG-Unit 8 Page 4 of 9

5 12. This picture show 2 gyres. a. Draw arrow heads on the gyres to show how the direction of flow. b. Describe the kind of weather condition is most likely to occur at i. Location A ii. Location C iii. Location E c. Explain which of the following pairs of locations will have warmer currents: i. G and H ii. C and D 13. Name the currents that surrounds Canada on the d. West Coast: e. East Coast: 14. Why are ocean currents important? ES11LG-Unit 8 Page 5 of 9

6 15. The diagram shows the Sargasso Sea with the lines around it representing the currents that bounds it. Label those currents. 16. What makes the Sargasso Sea unique from other large bodies of water? 8-3 The Ocean Floor 17. List some of the technologies used to study the ocean floor. 18. Label this picture of the ocean floor with the following terms: Seamount continental slope guyot shoreline abyssal plain abyssal hill continental shelf continental rise ES11LG-Unit 8 Page 6 of 9

7 19. Complete the crossword. Use the words above as answers to the puzzle clue 20. How and where do the following form? a. mid-ocean ridges b. rift valleys ES11LG-Unit 8 Page 7 of 9

8 21. Compare and contrast active and passive continental margins referencing the way they form, the features they each have etc. 22. Explain how each of the following formed: a. deep submarine b. abyssal fans c. abyssal hills d. seamounts e. reefs f. atoll ES11LG-Unit 8 Page 8 of 9

9 8-4 The Hydrologic 23. Water, like all matter, undergoes phase changes. You learn about these changes in previous science courses a. Either from memory or doing research, place the following terms into the correct arrow: Evaporation solidification condensation melting b. For each arrow in the diagram above put a + if energy is added or - if energy is removed for the phase change to happen. 24. Complete the sentences below with the following term: fresh water hydrologic cycle transpiration sun ground water ice caps lakes atmosphere swamps a. The describes the interaction of water between the and the earth s surface. b. The is the energy source for the water cycle. c. Most of the is in the and glaciers d. Surface waters includes,, and rivers e. About 30% of fresh water is stored as underground. f. Plants use to release water into the atmosphere. 25. Referring back to the hydrologic cycle, explain how you think plants move trapped groundwater found in soil into the atmosphere. ES11LG-Unit 8 Page 9 of 9
