Q. Consider the following statements:

1. Aryabhata asserted that the Earth is spherical and rotates on its own axis.
2. Seasons change due to the Earth's changing position around the Sun.

Which of the above statements is / are correct?
Answer: Both 1 and 2
Notes: Aryabhata, an ancient Indian astronomer, accurately described the Earth as round and rotating on its axis. Additionally, the change of seasons results from the Earth's revolution around the Sun and its axial tilt, causing the position relative to the Sun to vary throughout the year. Thus, both statements are correct and substantiated by scientific understanding.
