	Cold ocean currents often have a dramatic impact on the climate of tropical deserts along the west coasts of continents.    True  False

	In the Southern Hemisphere, ocean currents form counterclockwise gyres.    True  False

	Large whirls of water within ocean basins are called   waves monsoons gyres interfaces hemispheres

	The densest water in all of the oceans is formed in ____________ waters.   Equatorial North Pacific North Atlantic Indian Ocean Antarctic

	Which of the following is not a major oceanic gyre?   Westerly gyre Indian Ocean gyre N. Atlantic gyre S. Pacific Gyre N. Pacific gyre

	Deep-ocean circulation currents are referred to as ____________ circulation.   density ocean-floor abyssal thermohaline subsurface

	The ________________ flows along the East Coast of North America until it is deflected to the right by westerly winds.   Subtropical drift Gulf Stream North Equatorial current North Atlantic drift none of the above

	The large central area of the North Atlantic that has no well-defined currents is known as the ____________ Sea.   Dead Central Red Sargasso Baltic

	Other than wind, the most significant factor that influences the movement of ocean water at the surface is the   force of gravity ocean slope translation force density effect Coriolis effect

	Beaches consist of material in transit along the shore.    True  False

	Fetch is the distance the wind has traveled across open water.    True  False

	Most waves reach the shoreline perpendicular to the coast.    True  False

	In the open sea, it is the wave form that moves forward, not the water itself.    True  False

	The boundary between the land and the sea can be defined by the term   beach coastal zone coast shoreline all of the above

	The energy contributed by wind to water is transmitted only along the surface.    True  False

	The time it takes for one full wave to pass a fixed position is called   wavelength wave height wave period wave fetch none of the above

	The vertical distance between the trough of a wave and the crest of a wave is called   fetch wave period wavelength wave height none of the above

	A barrier built at a right angle to the beach to trap sand that is moving parallel to the shore is known as a   pier groin stack seawall none of the above

	A spit will often have a curved hook that extends out to sea because of the pull of the longshore current.    True  False

	A ridge of sand connecting an island to the mainland is called a   spit sea arch tombolo marine terrace sea stack

	Barrier islands originated or formed as   former beach-dune complexes now submerged after sea level rise large quantities of sand were deposited from turbulent water spits cut off from land by a general rise in sea level spits cut off from land by wave erosion all of the above

	Exposed wave-cut cliffs and platforms are frequently found along ____________ coasts.   static submergent emergent

	The shape of the coastline and shoreline features are determined entirely by wave erosion.    True  False

	Daily changes in the elevation of the ocean surface are called tides.    True  False

	Tidal deltas that form on the landward side of an inlet are called   tidal flats spring deltas ebb deltas flood deltas none of the above
