There is only one ocean. It is divided into five different parts: 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 many 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: II. WHILE YOU READ
1.Some plants and animal are referred to as------------ organisms because they are extremely small. 2. Thanks to modern technology, scientists have been able to------------ --- the life plants and animal that live under the sea. 3. A sea animal that eats fish and lives around coasts is a ----------------- 4. A-----------is a large area of sea that is partly surrounded by land. 5. -------------------is a term that refers to the existence of different kind of animal and plants which makes a balanced environment. 6. These scientists have collected different ---------------to analyze for their experiment. 7. A ---------------- is a large reptile with a hard round shell, that lives in the sea. gulf investigate oversized tiny biodiversity samples challenges provide seal turtle
Task 2: Read the passage again and answer the questions below:
1.What percentage of the earth’s surface is covered by seas and oceans? 75% of the earth’s surface is covered by the 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 help them to 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 population. 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 current. 6. What would happen if the sea biodiversity were not maintained? The marine life would be at stake if the sea biodiversity was not maintained.
