Unit 2 Oceanography
Lesson 1 Earth’s Ocean and the Ocean FloorLesson 2 Ocean WavesLesson 3 Ocean Currents
a movement of ocean water that follows a regular pattern
ocean current
the distance from any point on a wave to the corresponding point on
the next wave
wavelength
a measure of the amount of dissolved salts in a given amount of liquid
salinity
a giant ocean wave that forms after a volcanic eruption, submarine earthquake, or landslide
tsunami
the movement of deep, cold, and nutrient rich water to the surface
upwelling
a layer in a body of water in which water temperature drops with increased depth
faster than it does in other layers
thermocline
a wave that requires a medium through which to travel
mechanical wave
any movement of matter that results from differences in density; may be vertical, circular,
or cyclical
convention current
the shallow sea floor that is located between the shore-line and the deep ocean bottom; it is divided into the continental
shelf, the continental slope, and the continental rise
continental margin
a horizontal movement of water that is caused by wind and that occurs at or near the ocean’s surface
surface current
the highest point of a wave
crest
the ocean floor under the deep-ocean water
deep-ocean basin
time required for corresponding points on consecutive points on consecutive waves to pass a given point
wave period
a long under-sea mountain chain that forms along the floor of the
major oceans
mid-ocean ridge
a disturbance that transfers energy from one place to another; a wave can be a
single cycle or it can be a repeating pattern
wave
the lowest point of a wave
trough
the curving of the path of a moving object from an otherwise straight path due to Earth’s rotation
Coriolis Effect
a long, narrow, and deep depression on the ocean floor that forms when one tectonic plate subducts
beneath another plate; trenches run parallel to volcanic island chains or to the coastlines of
continents; also called a trench or a deep ocean trench
ocean trench
a stream-like movement of water far below the surface
deep current
a disturbance on the ocean that transmits energy and takes the shape of a swell or a ridge
