What is not a characteristic of western boundary currents? a. They move warm water poleward b. They are fast moving currents c. They are deep currents d. They are broad currents 29. What is not a characteristic of an El Niño Southern Oscillation? a. High pressure area shifts to the western Pacific b. Trade winds across the Pacific weaken or reverse directions e. Eastward movement of warm water along the equator d. Upwelling along the South American coast intensifies 30. Which of the following is false concerning the Ekman spiral? a. The movement of surface currents is the same direction as the wi nd above b. The velocity of an ocean current slows as water depth increases c. Current direction is affected by the Coriolis Force as currents deepen d. The Ekman spiral explains the phenomena of ocean currents flowing between 45° and 900 from prevailing wind direction 31. A transverse current is a. a bottom current flowing in the same direction as an overlying surface current. b. a surface current that connects eastern and western boundary currents. c. a cold current that flows from the poles towards the equator. d. a thermohaline current originating in Antarctica. 32. What is a gyre? a. A type of surface current. b. A circular flow of water around the periphery (edges) of an ocean basin. c. An upwelling circular current d. A type of current along the western margins of ocean basins 33. California's Climate is strongly affected by a: a. cold eastern boundary current. b. warm eastern boundary current. c. cold western boundary current. d. warm western boundary current.Explanation / Answer
27. In polar lattitude density stratification least pronounced.
28. Western boundary currents are broad current is not characteristics of this current.western boundary current s are warm, deep, narrow, and fast flowing currents.
29. All the options which are mentioned is characteristics of El Nino Southern Oscillation.
30. Last option is not satisfied the Ekman spiral. In this spiral movement of surface current is the same direction as wind above, also velocity of an ocean currents alow as water depth increases and current direction is affacted by Coriolis effcts.
31.A transverse currents are that currents which connected by eastern and western boundary currents within a certain gyre.
32. Gyre is a circular flow of water around the periphery of an ocean basin.
33. Warm western boundary currents affcts mostly of california's climate.
