Task 3
1. 75%
1. There is only one ocean . It is divided into five different parts : The Pacific ,Atlantic ,Indian , Antarctic , and Arctic Oceans . There are also other smaller seas , gulfs , and bays with form part of them .together ,they cover 75% of our Earth .For centuries , people have been challenged by the mysteries that lie beneath the blue depths of the ocean . We used to think that there was no life in the ocean depths .how different a picture we now have of the ocean as the sea has begun to reveal its secrets .
2.We used to think that there was no life in the ocean depths.

3.They can now reveal the secrets of the undersea world by using more sophisticated tools
2 .Today scientists have overcome many of the challenges of the deep by using more sophisticated tools .they can send submarines and devices to investigate the ocean depths ,taking photographs and samples of animal life to bring back to the surface for further study . Satellites photos provide a wide range of information including water temperature , depth and the undersea populations .Understanding the interactions of the oceans and marine life gives us an indication of the planet `s heath and the effects of human activity .
4 .We have information about the ocean`s depths ,water temperature photographs and samples of marine life and undersea populations

5 .We can know about the planet`s health and the effects of human activity from the interactions of the ocean and marine life.

6.They are those that live in the bottom , those that move independently of water currents and those that are carried along by the currents .
3. The plants and animals of the sea fall into three major groups: those that live on the bottom like starfish ,those that move independently of water currents like sharks and various small organisms that are carried along by the currents .We have a connection to all the living things of the oceans .From the tiny floating plants that supply us with the oxygen we breathe to huge blue whale that fills its belly with a ton of krill .Small oversized plant or animal , the ocean` s living things contribute to its endless variety ,its biodiversity .
7. They all contribute to the biodiversity of the ocean.

Task 4
Imagine that you are a diver .You have just returned from your exploration into the ocean depth .Tell your partner what did you see there and how could you explore the ocean depth ?
