Q1Consider the following statements about eclipses: 1. Every new Moon produces a solar eclipse. 2. A solar eclipse requires the Sun, Moon and Earth to align near the lunar orbital nodes. Which one of the following is correct?
Statement 2 only is correct. A new Moon is necessary for a solar eclipse, but the Moon's inclined orbit means that node alignment is also required. Most new Moons therefore do not produce a solar eclipse.
Q2Match List I with List II and select the correct answer using the code given below. List I (Planet): A. Mercury; B. Venus; C. Jupiter; D. Earth List II (Distinction): 1. Hottest planet; 2. Densest planet; 3. Largest planet; 4. Smallest planet
Mercury is the smallest planet, Venus is the hottest, Jupiter is the largest, and Earth is the densest among the planets. Thus the correct matching is A-4, B-1, C-3 and D-2, given in option C.
Q3Consider the following statements about insolation: 1. The same solar beam is spread over a smaller area at high latitudes than at low latitudes. 2. Insolation received at a place varies with factors such as latitude, season, time of day, cloud cover, altitude and slope. Which one of the following is correct?
Statement 2 only is correct. At high latitudes the same solar beam spreads over a larger, not smaller, area and passes through more atmosphere. Insolation also varies with the listed geographic and atmospheric controls.
Q4Arrange the following planets in increasing order of their distance from the Sun: A. Jupiter B. Earth C. Venus D. Mars Select the correct answer using the code given below.
The planetary order outward from the Sun is Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. Among the four listed planets, the increasing-distance order is Venus-Earth-Mars-Jupiter, or C-B-D-A, given in option C.
Q5With reference to Earth's rotation, consider the following statements: 1. Earth rotates from west to east. 2. The Coriolis effect is zero at the Equator and increases poleward. 3. A sidereal day is roughly 4 minutes longer than a mean solar day. Which of the statements given above are correct? Select the correct answer using the code given below.
Statements 1 and 2 are correct. West-to-east rotation produces the apparent daily east-to-west motion of celestial bodies and underlies the Coriolis effect. A sidereal day is roughly 4 minutes shorter, not longer, than a mean solar day.

6With reference to Earth's revolution and seasons, consider the following statements: 1. Earth is near perihelion in early January. 2. Earth's axis flips its direction during each annual revolution. 3. An equinox produces exactly 12 hours of day and 12 hours of night at every place on Earth.

7With reference to the Universe and astronomical evidence, consider the following statements: 1. The Big Bang model describes the expansion of space itself, not an explosion into pre-existing empty space. 2. A light-year is a unit of length. 3. The Solar System lies at the centre of the Milky Way. Which of the statements given above are correct? Select the correct answer using the code given below.
