The Earth is not a perfect sphere but is slightly flattened at the poles and bulging at the equator due to its rotation. This shape is often referred to as an oblate spheroid, meaning it is mostly spherical but slightly flattened at the poles and slightly bulging at the equator. The flattening is a result of the Earth's rotation, which causes it to be slightly compressed along its axis.

An autotroph is an organism that can produce its own food using light, water, carbon dioxide, or other chemicals. Because autotrophs produce their own food, they are sometimes called producers. Most autotrophs use a process called photosynthesis to make their food.

Chetak or Cetak is the name given in traditional literature to the horse ridden by Maharana Pratap at the Battle of Haldighati, fought on 18 June 1576 at Haldighati, in the Aravalli Mountains of Rajasthan, in western India.
