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.

Every drop of water in the ocean, even in the deepest parts, responds to the forces that create the tides. No other force that affects the sea is so strong. Compared with the tides, the waves created by the wind are surface movements felt no more than a hundred fathoms below the surface. The currents also seldom involve more than the upper several hundred fathoms despite their impressive sweep.

The tides are a response of the waters of the ocean to the pull of the Moon and the more distant Sun. In theory, there is a gravitational attraction between the water and even the outermost star of the universe. In reality, however, the pull of remote stars is so slight as to be obliterated by the control of the Moon and, to a lesser extent, the Sun.

Just as the Moon rises later each day by fifty minutes, on the average, so, in most places, the time of high tide is correspondingly later each day. And as the Moon waxes and wanes in its monthly cycle, so the height of the tide varies. The tidal movements are strongest when the Moon is a sliver in the sky, and when it is full. These are the highest flood tides and the lowest ebb tides of the lunar month and are called the spring tides. At these times the Sun, Moon, and Earth are nearly in line and the pull of the two heavenly bodies is added together to bring the water high on the beaches, to send its surf upward against the sea cliffs, and to draw a high tide into the harbors. Twice each month, at the quarters of the Moon, when the Sun, Moon, and Earth lie at the apexes of a triangular configuration and the pull of the Sun and Moon are opposed, the moderate tidal movements called neap tides occur. Then the difference between high and low water is less than at any other time during the month.

It can be inferred from the passage that the most important factor in determining how much gravitational effect one object in space has on the tides is

A. size

B. distance

C. temperature

D. density

Read the following passage and mark the letter (A, B, C or D) on your answer sheet to indicate the correct answer to each for the question.

Tides are the periodic rise and fall of the Earth’s waters that are caused by the Moon’s and Sun’s forces of gravity acting on the Earth .It is important to distinguish natural tidal phenomena from huge tsunamis , with the latter being caused by earthquakes and undersea volcanic eruptions.

The Moon is a main factor controlling ordinary tides. At the location on the Earth closest to the Moon, it exerts a powerful gravitational pull on the water. The resulting rise in the water produces higher tides. The water on the side of the Earth farthest away from the Moon also gets pulled by this lunar gravity, but not as strongly. The Earth itself has its own gravitational force that is constantly pulling waters downward, which is why the oceans do not simply bulge out toward the Moon. Ordinary tides usually feature high and low waters alternating in relation to the Earth’s rotation. Most shores around the world have high waters and two low waters for each day, which last about 24 hours and 50 minutes. The difference in height between the high water and low water is called the range of tide, and it can be quite dramatic in narrower bays .Canada’s bays of Fundy , for example , commonly experiences the world’s most extreme tidal ranges , with daily differences of the 16 meters.

Two other types of tides are influenced by the Sun, which is much farther away from the Earth and exerts less than half of the Moon’s gravitational force. When the Sun, the Moon and the Earth are directly in line, the solar and lunar gravitational forces add up to produce higher spring tides. The range of spring tides is intensified, with higher water marks and lower low water marks. However, when the Moon is in the first or third quarter, it is at a 90–degree angle with the Sun in relation to the Earth .The opposing solar and lunar forces partially cancel each other out, and the result is a lower tide. This is called a neap tide, which comes twice a month and has lower high water marks and higher low water marks. The range of neap tides is minimum.

Some tides do not occur over water at all. The solid body of the Earth has slight elasticity, so lunar and solar gravity cause it to stretch very subtly. These changes in the Earth’s shape, although imperceptible to humans, are known as Earth tides. Another tidal phenomenon, atmospheric tides, is caused by the Sun’s heating of the Earth’s atmosphere. Like ordinary tides, they usually occur over 12–hour periods.

What is true about the Moon’s gravitational force?

A. It pulls water on the far side of the Earth more strongly.

B. It is more than twice as powerful as that of the Sun.

C. It has reduced gravity when it is lined up with the Sun and the Earth.

D. Its force is strongest when it is located at 90 degrees to the Earth.

Đáp án là B.

Câu nào sau đây đúng về lực hút của mặt trăng?

A. Nó đẩy nước ở phía xa Trái Đất mạnh hơn.

B. Nó mạnh hơn mặt trời gấp hai lần.

C. Nó giảm trọng lực khi mặt trăng và mặt trời thẳng hàng với nhau.

D. Lực của nó mạnh nhất khi được đặt ở 90o so với Trái Đất.

Dẫn chứng: Two other types of tides are influenced by the Sun, which is much farther away from the Earth and exerts less than half of the Moon’s gravitational force.
