Unit 2 Oceanography Lesson 1 Earth’s Ocean and the Ocean Floor Lesson 2 Ocean Waves Lesson 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 deepocean 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 ocean wave
