Question
What are the significant lines of latitude? Explain the zones found between them.
Solution
The significant lines of latitude are.
- Equator 0°
- Tropic of cancer 23 1/2° N
- Tropic of Capricorn 23 1/2° S
- Arctic Circle 66 1/22°N
- Antarctic Circle 66 1/2° S
- North Pole 90° N
- South Pole 90° S
- Based on the amount of heat received from the sun, our world is broadly divided into three heat zones.
- The Torrid Zone: On both sides of the equator, the region lying between the Tropic of cancer and the Tropic of Capricorn is called the Torrid zone. This zone gets the direct rays of the sun all year-round. Hence the climate is hot and humid.
- The Temperature Zone: This zone is neither hot nor very cold. It lies between the Torrid zone and Frigid zone in both the hemispheres.
- The Frigid Zone: The region lying between the Arctic circle and North pole and between the Antarctic circle and the south pole is called the frigid zone. It receives very slanting rays of the sun and is therefore very cold.
