To a perpendicular to the plane of ecliptic, Earth's axis of rotation makes an angle of 23 1 2 degrees. Had this angle been zero degree, which one among the following would result ?

Options

  1. AThere would have been no season
  2. BThe length of day and night would have been the same throughout the year
  3. CThe length of the day and night would have been the same all over the earth
  4. DAll of the above

Correct answer

A. There would have been no season

Step-by-step solution

In astronomy, axial tilt (also called obliquity) is the angle between an object's rotational axis and the perpendicular to its Orbital plane, both oriented by the right hand rule. At an obliquity of 0°, these lines point in the same direction i.e. the rotational axis is perpendicular to the orbital plane. Axial tilt differs from inclination. Over the course of an orbit, the angle of the axial tilt does not change, and the orientation of the axis remains the same relative to the background stars. This causes one pol
