- Equator
- 'Equator' is described as 'an imaginary line that passes around the Earth's centre.
- It is equidistant from the two poles(North, as well as, South) leading the division of the Earth into two equal hemispheres namely Northern and Southern Hemisphere.
- The Equator cuts the upper portion of South America as it passes through it and therefore, the regions located near it have extremely high temperatures making it difficult for human survival.
