Question 1 • Which ocean is the largest ocean on the Earth’s surface? • Pacific Ocean
Question 2 • Which of the following is the correct value stating how much of the Earth’s total mass the oceans make up? • 1/10 • 1/100 • 1/4000 • 1/40000 • 1/4000
Question 3 • What describes a system that uses acoustic signals and returned echoes to determine the location of objects • Sonar
Question 4 • What are the two major areas the ocean floor can be divided into? • Continental margins and deep-ocean basins
Question 5 • What is the shallow sea floor that is located between the shoreline and the deep-ocean bottom? • Continental margin
Question 6 • What is the part of the ocean floor that is under deep water beyond the continental margin? • Deep-ocean basin
Question 7 • Name 4 features characteristic of continental margins. • Continental Slopes, submarine canyons, turbidity currents, continental rises
Question 8 • Name at least 4 features characteristic of a deep-ocean basin. • Trenches, abyssal plains, mid-ocean ridges, abyssal hills, fracture zones, seamounts, guyots, atolls
Question 9 • Where are seamounts often formed near? • Areas of increased volcanic activity called HOT SPOTS
Question 10 • What are continental shelves and slopes often covered with? • Sediments
Question 11 • Sediments, rocks, soil, snow that are often collected from the deep-ocean basin by drilling are called what? • Core Samples
Question 12 • What are lumps of minerals that are made of oxides of manganese, iron, copper, or nickel that is scattered in groups on the ocean floor? • Nodules
Question 13 • Sediments on the ocean floor such as the remains of marine plants and animals are examples of what? • Biogenic sediments
Question 14 • What are the two main gases dissolved in ocean water? • Nitrogen and oxygen (same as atmosphere)
Question 15 • Gases dissolve more readily in cold water or warm water? • Cold water
Question 16 • Where does most oxygen in the ocean enter from? • Atmosphere
Question 17 • Which of the following are factors that affect the salinity of ocean water? (There are two) • Density • Light • Energy • Chemicals • Temperature • Density and temperature
Question 18 • What is the process of removing salt from ocean water? • Desalination
Question 19 • What is a layer of body of water in which water temperature drops with increased depth faster than it does in other layers • Thermocline
Question 20 • If 60% of sea salts is Chloride ions, how much chloride ions are present in 500g sample? • 300g
Question 21 • If sonar is used to measure the depth in a particular area of the ocean and the time it took for the waves to hit the ocean floor and then the surface of the ocean was 3.9 seconds and the speed is 1400 ft/sec, what is the depth. • 700 ft/sec x (3.9 sec) = 2730 ft
Question 22 • What is the density of oxygen gas if 0.369 g occupies a volume of 567 mL? • 0.369 g / 567 mL = 6.51 g/mL • Don’t forget your units!!!
Question 23 • A Sample of wood has the dimensions of 5cm x 3cm x 4 cm. If the mass of the wood is 456 g, what is the density of wood? • (5cm x 3cm x 4cm)= 60 cm^3 456 / 60 cm^3 = 7.6 g / cm^3
