Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions

If the salinity of ocean waters is analyzed, it is found to vary only slightly from place to place. Nevertheless, some of these small changes are important. There are three basic processes that cause a change in oceanic salinity. One of these is the subtraction of water from the ocean by means of evaporation-conversion of liquid water to water vapor. In this manner, the salinity is increased, since the salt behind. If this is carried to the extreme, of course, white crystals of salt would be left behind.

The opposite of evaporation is precipitation, such as rain, by which water is added to the ocean. Here the ocean is being diluted so that the salinity is decreased. This may occur in areas of high rainfall or in coastal regions where rivers flow into the ocean. Thus salinity may be increased by the subtraction of water by evaporation, or decreased by the addition of fresh water by precipitation or runoff.

Normally, in tropical regions where the sun is very strong, the ocean salinity is somewhat higher than it is in other parts of the world where there is not as much evaporation. Similarly, in coastal regions where rivers dilute the sea, salinity is somewhat lower than in other oceanic areas.

A third process by which salinity may be altered is associated with the formation and melting of sea ice. When seawater is frozen, the dissolved materials are left behind. In this manner, seawater directly beneath freshly formed sea ice has a higher salinity than it did before the ice appeared. Of course, when this ice melts, it will tend to decrease the salinity of the surrounding water.

In the Weddell Sea, off Antarctica, the densest water in the ocean is formed as a result of this freezing process, which increases the salinity of cold water. This heavy water sinks and is found in the deeper portions of the oceans of the world.

Which of the following is NOT a result of the formation of ocean ice?

A. The surrounding water sinks

B. Water salinity decreases

C.The salt remains in the water

D. The water becomes denser

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 43 to 50.

If the salinity of ocean waters is analyzed, it is found to vary only slightly from place to place. Nevertheless, some of these small changes are important. There are three basic processes that cause a change in oceanic salinity. One of these is the subtraction of water from the ocean by means of evaporation-conversion of liquid water to water vapor. In this manner, the salinity is increased, since the salts stay behind. If this is carried to the extreme, of course, white crystals of salt would be left behind: this, by the way, is how much of the table salt we use is actually obtained.

The opposite of evaporation is precipitation. such as rain, by which water is added to the ocean. Here the ocean is being diluted so that the salinity is decreased. This may occur in areas of high rainfall or in coastal regions where rivers flow into the ocean. Thus salinity may be increased by the subtraction of water by evaporation, or decreased by the addition of fresh water by precipitation or runoff.

Normally in tropical regions where the Sun is very strong, the ocean salinity is somewhat higher than it is in other parts of the world where there is not as much evaporation. Similarly, in coastal regions where rivers dilute the sea salinity is somewhat lower than in other oceanic areas.

A third process by which salinity may be altered is associated with the formation and melting of sea ice. When seawater is frozen, the dissolved materials are left behind. In this manner, seawater directly beneath freshly formed sea ice has a higher salinity than it did before the ice appeared. Of course, when this ice melts, it will tend to decrease the salinity of the surrounding water.

In the Weddell Sea, off Antarctica, the densest water in the oceans is formed as a result of this freezing process, which increases the salinity of cold water. This heavy water sinks and is found in the deeper portions of the oceans of the world

All of the following are processes that decrease salinity EXCEPT

A. evaporation

B. precipitation

C. runoff

D. melting

Theo đoạn văn, đại dương thường có nhiều muối trong

Thông tin: Normally, in tropical regions where the sun is very strong, the ocean salinity is somewhat higher than it is in other parts of the world where there is not as much evaporation.

Tạm dịch: Thông thường, ở các vùng nhiệt đới nơi mặt trời rất mạnh, độ mặn của đại dương có phần cao hơn so với các khu vực khác trên thế giới, nơi không có nhiều sự bốc hơi.

Chọn D

Dịch bài đọc:

Nếu độ mặn của nước biển được phân tích, nó được tìm ra rằng nó chỉ thay đổi một chút từ nơi này sang nơi khác. Tuy nhiên, một số thay đổi nhỏ này rất quan trọng. Có ba quá trình cơ bản gây ra sự thay đổi độ mặn của đại dương. Một trong số đó là phép trừ nước từ đại dương bằng phương pháp bay hơi - chuyển đổi nước lỏng thành hơi nước. Theo cách này, độ mặn được tăng lên, vì muối sót lại. Nếu điều này được thực hiện đến cùng cực, tất nhiên, các tinh thể muối trắng sẽ bị để lại.

Đối lập với sự bốc hơi là kết nước, chẳng hạn như mưa, qua đó nước được thêm vào đại dương. Ở đây đại dương đang bị pha loãng để độ mặn giảm. Điều này có thể xảy ra ở những khu vực có lượng mưa lớn hoặc ở những vùng ven biển nơi sông chảy vào đại dương. Do đó, độ mặn có thể được tăng lên bằng cách trừ nước bằng cách bay hơi, hoặc giảm khi bổ sung nước ngọt bằng lượng mưa hoặc dòng chảy.

Thông thường, ở các vùng nhiệt đới nơi mặt trời rất mạnh, độ mặn của đại dương có phần cao hơn so với các khu vực khác trên thế giới, nơi không có nhiều sự bốc hơi. Tương tự, ở các vùng ven biển nơi các con sông làm loãng biển, độ mặn có phần thấp hơn so với các khu vực đại dương khác.

Một quá trình thứ ba mà độ mặn có thể bị thay đổi có liên quan đến sự hình thành và tan chảy của băng biển. Khi nước biển bị đóng băng, các vật liệu hòa tan bị bỏ lại. Theo cách này, nước biển trực tiếp bên dưới băng biển mới hình thành có độ mặn cao hơn so với trước khi băng xuất hiện. Tất nhiên, khi băng này tan ra, nó sẽ có xu hướng làm giảm độ mặn của nước xung quanh.

Ở biển Weddell, ngoài khơi Nam Cực, nước dày đặc nhất trong đại dương được hình thành là kết quả của quá trình đóng băng này, làm tăng độ mặn của nước lạnh. Nước nặng này chìm xuống và được tìm thấy ở những nơi sâu hơn của các đại dương trên thế giới.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 43 to 50.

If the salinity of ocean waters is analyzed, it is found to vary only slightly from place to place. Nevertheless, some of these small changes are important. There are three basic processes that cause a change in oceanic salinity. One of these is the subtraction of water from the ocean by means of evaporation-conversion of liquid water to water vapor. In this manner, the salinity is increased, since the salts stay behind. If this is carried to the extreme, of course, white crystals of salt would be left behind: this, by the way, is how much of the table salt we use is actually obtained.

The opposite of evaporation is precipitation. such as rain, by which water is added to the ocean. Here the ocean is being diluted so that the salinity is decreased. This may occur in areas of high rainfall or in coastal regions where rivers flow into the ocean. Thus salinity may be increased by the subtraction of water by evaporation, or decreased by the addition of fresh water by precipitation or runoff.

Normally in tropical regions where the Sun is very strong, the ocean salinity is somewhat higher than it is in other parts of the world where there is not as much evaporation. Similarly, in coastal regions where rivers dilute the sea salinity is somewhat lower than in other oceanic areas.

A third process by which salinity may be altered is associated with the formation and melting of sea ice. When seawater is frozen, the dissolved materials are left behind. In this manner, seawater directly beneath freshly formed sea ice has a higher salinity than it did before the ice appeared. Of course, when this ice melts, it will tend to decrease the salinity of the surrounding water.

In the Weddell Sea, off Antarctica, the densest water in the oceans is formed as a result of this freezing process, which increases the salinity of cold water. This heavy water sinks and is found in the deeper portions of the oceans of the world

Which of the following statements about the salinity of a body of water can best be inferred from the passage?

A. The temperature of the water is the most important factor.

B. How quickly the water moves is directly related to the amount of alt.

C. Ocean salinity has little effect on sea life.

D. Various factors combine to cause variations in the salt content of water.
