"cool phase"

Which is more dense, warm water or cold water?

highest point of the wave

________ occurs when the winds are weaker and there are warmer than normal temperatures along the equator.

Currents on the surface, which take up about 10% of the oceans, are caused by winds that blow over them

part of the ocean that extends from the continental, marking the edge of the continents

accumulation of sediment from rivers that is deposited at the base of a submarine canyon

A volcanic mountain found on an ocean basin that has an origin not related to a mid-oceanic ridge

Where can warm water be found?

lowest point of the wave

Shallow submerged margin of the continents that lies between the edge of the shoreline and the continental slope

_______ occurs when the winds are stronger and there are cooler than normal temperatures in the same region of the ocean

When cold, deep water rises, it brings with it lots of nutrients from the ocean floor in a process known as

An elevated area of land created from the release of lava and ejection of ash and rock fragments from and volcanic vent.

these currents are the remaining 90% of ocean currents

a gyre in the pacific created by the circular currents in which over 700,000 tons of garbage is trapped

The dominant pattern of surface circulation is the ______ - a well­ organized, roughly circular flow

height of a wave as measured from the highest point on the wave

"warm-phase"

An opening on a volcano through which lava is released and rock fragments and ash are ejected.

normally found rising above the ocean floor at the center of the ocean basins

One surface current circles endlessly around ______________

Which is more dense, salty water or less salty water?

Steep sided valley found on the Earth's surface created by tectonic rifting (Zone between two diverging tectonic plates)

__________ is the most important cause of surface currents

Granitic portion of the Earth's crust that makes up the continents

currents move at an angle to the force that generates them–a phenomenon called the ______________

Changes in the ___________ ocean cause El Nino and La Nina

the length of a wave from one peak to the next

long, narrow, steep-sided depressions found on the ocean floor that contain the greatest depths in the ocean

V-shaped canyons cut into the continental slope

found at the base of the continental slope
