The 20th Parallel is an imaginary line of latitude located 20 degrees north of the equator. It circles the Earth and is used in geography to help identify locations and regions. This parallel passes through several countries, including Mali, Niger, Chad, and India. In addition to its geographical significance, the 20th Parallel is often referenced in discussions about climate and ecosystems. Regions along this line typically experience a tropical climate, which influences the types of vegetation and wildlife found there. Understanding the 20th Parallel can help in studying global patterns of weather and biodiversity.
