Transcription

1 Science 5 - Sawyer Oceans [Exam I:6030] 1 Koa and Neeve are swimming and jumping in the waves at the beach. On which part of the ocean are they standing? Mountain range ontinental rise byssal plain ontinental shelf 2 If all the water in the ocean were removed, what would the land below it look like? Mostly flat like a desert Mostly small hills and grasslands Mostly mountains and valleys Similar to land on the continents

2 3 Which number shows where the ontinental slope is? #2 #3 #1 #4 4 n ocean trench is represented by which number?

3 5 Number 4 represents which of these? The ontinental slope n Oceanic trench The ontinental shelf n byssal plain 6 t which location are oceans the deepest? Volcanic island byssal plain Mid ocean ridge Ocean trench 7 Which best describes the part of the ocean called the continental shelf? region with a higher water pressure shallow area of sediment near the shore region of mountains in the deep ocean flat underwater valley

4 8 Which section represents the abyssal plain? Section 5 Section 1 Section 2 Section 3

5 9 Which section represents the continental rise? Section 1 Section 5 Section 2 Section 3 10 When water evaporates from the surface of the ocean salt evaporates into the air salt is left behind the water is polluted fresh water is left behind 11 Most of the salt in the oceans came from space lakes land rivers

6 12 Which of the following is not a cause of ocean currents? Wind directions ifferences in salinity Water and air pollution Temperature changes 13 If a sailor left North merica from the tlantic Ocean, he could follow the current to Europe hina Russia ustralia

7 14 Which of these numbers represents the location of the ulf Stream on this map? #3 #4 #2 #1

8 15 ccording to this graph at what depth is the water temperature the coolest? 1000 ft 2000 ft 4000 ft 5000 ft

9 16 This picture is which of these ocean motions? Tides lows urrents Waves 17 What happens to the water pressure in the ocean as the water gets deeper? It stays the same as you go down. It decreases then it increases. It decreases as you go down. It increases as you go down.

10 18 The main difference between ocean water and lake water is that ocean water contains oxygen algae salt plants 19 Which location is likely to have the greatest water pressure, the coldest temperatures, and the smallest number of living organisms? Submarines have explored many parts of the ocean. s submarines descend, scientists observe that there is an increase in the water temperature water pressure types of ocean organisms amount of light

11 21 What do the arrows on the map represent? Time between tides Ocean currents Water density Size of waves 22 Ms. ung's class placed a small container of salt water in a classroom window. What might they expect to find if the water is left alone for a few weeks? More water Empty container Only salt resh water

12 23 Producers that live in ecosystems near the ocean's surface receive their energy from sunlight sea animals salt chemical reactions 24 Which of the following is a producer in an ocean food chain? Phytoplankton nchovy Shark ristle worm 25 Organisms that live in the deep ocean where no light is found get energy from chemical reactions salt sunlight flowing water

13 26 Which of these organisms is the basis of the marine food chain? Lobster Phytoplankton Whale Shrimp

14 27 t which depth are there the least number of organisms? 80 ft 20 ft 60 ft 40 ft 28 Which answer gives the correct order of an ocean biome's food chain? Sun, phytoplankton, seal, fish, shark Shark, fish, seal, phytoplankton, sun Shark, seal, phytoplankton, fish, sun Sun, phytoplankton, fish, seal, shark opyright Interactive chievement, Inc. - Printed on 12/12/2011
