PPT-Chapter 13: Life in the Ocean

Main Concepts All of Earth s lifeforms are related All have apparently evolved from a single ancient instant of origin Evolution happens Organisms change as time passes adapting by natural selection to their environments Oceanic life is classified by evolutionary heritage. Vocabulary. Ocean Current. Coriolis Effect. Rip Current. Upwelling. Major Ocean Currents. An . Ocean Current. is a large volume of water flowing in a certain direction.. Wind-driven currents are called surface currents.. Ocean Zones. Which Zone?. 1. Each . group. . will be given a set of words that relate to the different zones of the ocean.. 2. At your table you will . try and place . your words in the correct zone.. For tens of millions of years, Earth's oceans have maintained a relatively stable acidity level. It's within this steady environment that the rich and varied web of life in today's seas has arisen and flourished. But research shows that this ancient balance is being undone by a recent and rapid drop in surface pH that could have devastating global consequences.. -. Julian Oscillation. . . Toshiaki .

How do different currents form. What is upwelling. What do ocean currents transfer. Predict. T F. Ocean currents are always cold. C. ontinents affect the direction of currents. Currents only flow near the surface of the ocean. life forms are related. . Evolved . from a single ancient instance of origin. Organisms change as time . passes (evolution), . adapting by natural selection to their environments. All life activity is involved, directly or indirectly, in energy transformation and transfer. Main . Concepts. All of Earth. ’. s life-forms are related. All have apparently evolved from a single ancient instant of origin.. Evolution happens. . Organisms change as time passes, adapting by natural selection to their environments. Oceanic life is classified by evolutionary heritage.. . Ocean Decade Research .

Submersibles, satellites, and other technology allow scientists to study the structure and composition of the ocean floor.. a. system that uses transmitted and reflected sound waves to measure distances to the ocean floor; SONAR. A: Sunlight – Producers require sunlight for photosynthesis. Ocean life is determined by many factors:. B: Temperature – most animals live near the surface where it is warmer. Ocean life is determined by many factors:. The Vast World . Ocean. Area of Continents and Oceans. Seventy one percent (71%) of the globe is covered with oceans or seas..
