3. 56.5 degrees
4. 46.5 degrees

Q. Earth rotates around its polar axis which is tilted at an angle of _________ degrees.

1. 0.5 degrees
2. 10.5 degrees
3. 23.5 degrees
4. 15.5 degrees

Q. The Earth's orbital plane passes through which of the following?

1. North pole of the Earth
2. Centre of the Earth
3. Centre of the Sun
4. Centre of Moon

Q. ____________ is the point where the Earth is the nearest to the Sun at 147 million kms.

Q. The moon is a major influence on the Earth’s tides, but the Sun also generates considerable tidal forces. Solar tides are about half as large as lunar tides and are expressed as a variation of lunar tidal patterns, not as a separate set of tides. For the purposes of our study, let us consider just the Earth-Sun system. At what point (if any) on the Earth's orbit around the Sun do you think that the tidal ranges will be enhanced?

1. At the Aphelion.
2. At the Perihelion.
3. Exactly at the centre of the Aphelion and Perihelion.
4. It is the same at any point on the Earth orbit.

Q. Select the correct option based on the following statements.
Statement 1: The Earth rotates around its polar axis with an axial tilt of 23.5 degrees.
Statement 2: The Earth experiences variation in the length of day and night around the northern and southern poles.

1. Both statements are false.
2. Statement 1 is true while Statement 2 is false.
3. Both statements are true and Statement 1 is responsible for Statement 2.
4. Both statements are true and Statement 2 is responsible for Statement 1.
