Read the passage and do the task that follow

There is only one ocean It is divided into five different parts:θ] the Pacific, Atlantic ,Indian, Antarctic, and Arctic Oceans There are also many

other smaller seas, gulfs and bays which form part of them Altogether they cover 75 percent of the earth’s surface For centuries, people have been

challenged by the mysteries that lie beneath the ocean However, today’s

scientists have overcome may of the challenges of the depth by using modern devices They send submarines to investigate the seabed and bring samples of marine life back to the surface for further study Satellite photographs provide a wide range of information, including water temperature, depth and the

undersea populations If modern technology did not exist, we would never have such precious information

Marine plants and animals fall into three major groups Some of them live on or depend on the bottom like the starfish Some are swimming animals such as fishes and sharks that move independently of water currents while

others are tiny organisms that are carried along by the currents like the jellyfish Plants and animals of the sea, however small or oversized, all contribute to its biodiversity Unless this biodiversity were maintained, marine life would be at stake

Task 1 The words in the box all appear in the passage Fill each blank

with one of them.There are more words than needed

gulf oversized biodiversity challenges

1 Some plants and animals are referred to as organisms

because they are extremely small

2 Thanks to modern technology, scientists have been able to the life of plants and animals that live under the sea

3 A is a large area of sea that is party surrounded by land

4 is a term that refers to the existence of different kinds of animals and plants which make a balanced environment

5 These scientists have collected different to analyse for

Task 2 Answer these questions

1 What percentage of the earth’s surface is covered

by seas and oceans?

75% of the earth’s surface

1 What percentage of the earth’s surface is covered

by seas and oceans?

2 How do scientists now overcome the challenges of the depth?

By using modern devices

3 What can submarines do to help scientists know about the undersea world?

They investigate the seabed and bring samples of the marine life back to the surface for further study

4 What can we learn from the

satellite photos?

We can know a wide range of information, including water temperature, depth and the undersea populations

5 What are the three groups of marine plants and animals?

They are those that live on or depend on the

bottom like the starfish, those that move

independently of water currents and those that are carried along by the currents

6 What would happen if the sea biodiversity were not maintained?

The marine life would be at stake if the sea biodiversity were not maintained
