Which among the following option is correct with respect to tides? 1. Spring tides occur when the sun, the moon and the earth are in a straight line. 2. Neap tides occur when the sun and moon are at right angles to each other.

Which among the following option is correct with respect to tides? 1. Spring tides occur when the sun, the moon and the earth are in a straight line. 2. Neap tides occur when the sun and moon are at right angles to each other. Correct Answer Both 1 and 2

The correct answer is option 3, i.e Both 1 and 2.

  • The periodical rise and fall of the water level in oceans and sea, once or twice a day, due to the gravitational pull of the sun and the moon, is called a tide.
  • Based on the position of sun, earth and moon, there are two kinds of tides which are shown in the picture given below:
  • Spring Tides:
    • When the position of the sun, the moon, and the earth are aligned in such a way that it forms a straight line, the height of the tide will be higher than normal. These are called as spring tides.
    • It occurs twice in a month-one on the full moon and the other on the new moon.
  • Neap Tides:
    • After seven days of spring tides the sun and the moon form a 90-degree angle between each other.
    • The resultant force of gravitation gives rise to a tide of very low magnitude which is termed as the neap tide.
    • It also occurs twice in a month.

The moon looks blood red during a total lunar eclipse because some of the sunlight passes through Earth’s atmosphere to reach the moon. As the white light breaks up while passing through the atmosphere, most of its blue-colored wavelengths are absorbed and scattered. The remaining red wavelengths light up the moon in blood-red color. Which of the following statements do not support the assertion of the above-given statement? I: The moon looks blood red during a total lunar eclipse as the white light breaks up due to the Earth's atmosphere where most of its red-colored wavelengths are absorbed. II: The moon looks blood red during a total lunar eclipse as the earth blocks the white light to travel to the moon.
In the following question, out of the four alternatives, select the alternative which will improve the underlined part of the sentence. In case no improvement is needed, select “No improvement”. When the Sun, the Moon, and the Earth are aligned in a straight line or an almost straightly configuration, such that the Moon comes between the Sun and Earth blocking the rays of Sun from directly reaching the Earth, we witness a solar eclipse.
At neap tide:
1. the sun and moon exert their force at right angles
2. the tidal amplitude is high
3. the low tides are very low
In a lunar month, ____ spring tides and _____ neap tides occur.
The question below consists of a set of labelled sentences. Out of the four given options, select the most logical order of the sentences to form a coherent paragraph. P- Such a scenario allows for it to have a profound influence on the tides of our oceans, which in turn serves to slow earth’s rotation and hurl the moon further away from us. Q- The gravitational attraction of the moon is also the stabilising factor in a celestial battle between the large bodies of the solar system to throw the planet’s axial obliquity off-balance.  R- The bulk of the moon’s responsibility for impacting upon the planet lies with its gravitation and proximity to the earth. S- The very fact that the moon is here in the first place tells of how fortunate the impact that formed it was. Were it not for that humble collision over 4.5 billion years ago, life on earth would be vastly different today.
