Direction: Read the case study given below and answer any three of the questions that follow.
The distribution of matter and energy was not even in the early universe. These initial density differences gave rise to differences in gravitational forces and it caused the matter to get drawn together. These formed the bases for development of galaxies. A galaxy contains a large number of stars. Galaxies spread over vast distances that are measured in thousands of light-years. The diameters of individual galaxies range from 80,000-150,000 light years. A galaxy starts to form by accumulation of hydrogen gas in the form of a very large cloud called nebula. Eventually, growing nebula develops localised clumps of gas. These clumps continue to grow into even denser gaseous bodies, giving rise to formation of stars. The formation of stars is believed to have taken place some 5-6 billion years ago. A light year is a measure of distance and not of time. Light travels at a speed of 300,000 km/second. Considering this, the distances the light will travel in one year is taken to be one light year. This equals to 9.461 × 1012 km. The mean distance between the sun and the earth is 149,598,000 km. In terms of light years, it is 8.311 minutes. Our Solar system consists of eight planets. The nebula from which our Solar system is supposed to have been formed, started its collapse and core formation some time 5-5.6 billion years ago and the planets were formed about 4.6 billion years ago. Our solar system consists of the sun (the star), 8 planets, 63 moons, millions of smaller bodies like asteroids and comets and huge quantity of dust grains and gases. Out of the eight planets, Mercury, Venus, Earth and Mars are called as the inner planets as they lie between the sun and the belt of asteroids. The other four planets are called the outer planets. Alternatively, the first four are called Terrestrial, meaning earthlike as they are made up of rock and metals, and have relatively high densities. The rest four are called Jovian or Gas Giant planets. Jovian means Jupiter-like. Most of them are much larger than the terrestrial planets and have thick atmosphere, mostly of helium and hydrogen. All the planets were formed in the same period sometime about 4.6 billion years ago. Till recently (August 2006), Pluto was also considered a planet. However, in a meeting of the International Astronomical Union, a decision was taken that Pluto like other celestial objects (2003 UB313) discovered in recent past may be called ‘dwarf planet.

Understanding the Solar System Composition
The question revolves around the composition of our solar system, specifically focusing on the number of planets and moons.
Key Components of the Solar System
- Our solar system is primarily made up of:
- The Sun: The central star.
- 8 Planets: These include Mercury, Venus, Earth, Mars (inner or terrestrial planets) and Jupiter, Saturn, Uranus, Neptune (outer or Jovian planets).
- 63 Moons: These are natural satellites that orbit the planets.
Correct Answer Explanation
- The correct answer is option 'B': 8 planets, 63 moons.
- This aligns with the information provided in the case study, stating that the solar system consists of 8 planets and specifically mentions 63 moons.
Why Other Options are Incorrect
- Option 'A' (8 planets, 62 moons): Incorrect, as it undercounts the number of moons.
- Option 'C' (8 planets, 65 moons): Incorrect, as it overcounts the number of moons.
- Option 'D' (8 planets, 67 moons): Also incorrect for the same reason as option C.
Conclusion
- The case study provides clear data regarding the structure of our solar system. Therefore, the correct answer, which specifies that our solar system contains 8 planets and 63 moons, is supported by the details outlined in the text.

Direction: Read the case study given below and answer any three of the questions that follow.The causes for climate change are many. They can be grouped into astronomical and terrestrial causes. The astronomical causes are the changes in solar output associated with sunspot activities. Sunspots are dark and cooler patches on the sun which increase and decrease in a cyclical manner. According to some meteorologists, when the number of sunspots increase, cooler and wetter weather and greater storminess occur. A decrease in sunspot numbers is associated with warm and drier conditions. Yet, these findings are not statistically significant. Another astronomical theory is Milankovitch oscillations, which infer cycles in the variations in the earth’s orbital characteristics around the sun, the wobbling of the earth and the changes in the earth’s axial tilt. All these alter the amount of insolation received from the sun, which in turn, might have a bearing on the climate. Volcanism is considered as another cause for climate change. Volcanic eruption throws up lots of aerosols into the atmosphere. These aerosols remain in the atmosphere for a considerable period of time reducing the sun’s radiation reaching the Earth’s surface. After the recent Pinatubo and El Cion volcanic eruptions, the average temperature of the earth fell to some extent for some years. The most important anthropogenic effect on the climate is the increasing trend in the concentration of greenhouse gases in the atmosphere which is likely to cause global warming.Q.

The formation of stars is believed to have taken place some 5-6 billion years ago. A light year is a measure of distance and not of time. Light travels at a speed of 300,000 km/second. Considering this, the distances the light will travel in one year is taken to be one light year. This equals to 9.461 × 1012 km. The mean distance between the sun and the earth is 149,598,000 km. In terms of light years, it is 8.311 minutes. Our Solar system consists of eight planets. The nebula from which our Solar system is supposed to have been formed, started its collapse and core formation some time 5-5.6 billion years ago and the planets were formed about 4.6 billion years ago. Our solar system consists of the sun (the star), 8 planets, 63 moons, millions of smaller bodies like asteroids and comets and huge quantity of dust grains and gases. Out of the eight planets, Mercury, Venus, Earth and Mars are called as the inner planets as they lie between the sun and the belt of asteroids. The other four planets are called the outer planets. Alternatively, the first four are called Terrestrial, meaning earthlike as they are made up of rock and metals, and have relatively high densities. The rest four are called Jovian or Gas Giant planets. Jovian means Jupiter-like. Most of them are much larger than the terrestrial planets and have thick atmosphere, mostly of helium and hydrogen. All the planets were formed in the same period sometime about 4.6 billion years ago. Till recently (August 2006), Pluto was also considered a planet. However, in a meeting of the International Astronomical Union, a decision was taken that Pluto like other celestial objects (2003 UB313) discovered in recent past may be called ‘dwarf planet.Q. Our solar system consists of the sun (the star), _______planets, __________ moons, millions of smaller bodies like asteroids and comets and huge quantity of dust grains and gasesa)8 planets, 62 moonsb)8 planets, 63 moonsc)8 planets, 65 moonsd)8 planets, 67 moonsCorrect answer is option 'B'. Can you explain this answer?, a detailed solution for Direction: Read the case study given below and answer any three of the questions that follow.The distribution of matter and energy was not even in the early universe. These initial density differences gave rise to differences in gravitational forces and it caused the matter to get drawn together. These formed the bases for development of galaxies. A galaxy contains a large number of stars. Galaxies spread over vast distances that are measured in thousands of light-years. The diameters of individual galaxies range from 80,000-150,000 light years. A galaxy starts to form by accumulation of hydrogen gas in the form of a very large cloud called nebula. Eventually, growing nebula develops localised clumps of gas. These clumps continue to grow into even denser gaseous bodies, giving rise to formation of stars.
