1. Tropic of Cancer: 23.5° N 2. Antarctic Circle: 66° S 3. Equator: 0° Latitude 4. Tropic of Capricorn: 23.5° S 5. Arctic Circle: 66° N 6. Prime Meridian: 0° Longitude

Certainly! Here's the list of specific latitudinal and longitudinal lines and their significance: 1. **The latitude located at 23.5° north of the equator:** This is the **Tropic of Cancer**. It is significant because it represents the northernmost point where the sun can be directly overhead at noon. This occurs around June 21st during the summer solstice in the Northern Hemisphere. 2. **The latitude located at 66° south of the equator:** This is the **Antarctic Circle**. It is significant as it marks the southernmost point at which the sun can remain continuously above or below the horizon for 24 hours—during the December solstice (around December 21st). 3. **The latitude at 0°:** This is the **Equator**. It is significant because it divides the Earth into the Northern and Southern Hemispheres and is the point of zero degrees latitude. The equator experiences nearly equal lengths of day and night throughout the year and has a consistently warm climate. 4. **The latitude located at 23.5° south of the equator:** This is the **Tropic of Capricorn**. It is significant because it represents the southernmost point where the sun can be directly overhead at noon. This occurs around December 21st during the summer solstice in the Southern Hemisphere. 5. **The latitude located at 66° north of the equator:** This is the **Arctic Circle**. It is significant as it marks the northernmost point at which the sun can remain continuously above or below the horizon for 24 hours—during the June solstice (around June 21st). 6. **The longitude at 0°:** This is the **Prime Meridian**. It is significant as it serves as the starting point for measuring longitude, dividing the Earth into the Eastern and Western Hemispheres. The Prime Meridian runs through Greenwich, London, and is an essential reference for timekeeping (Greenwich Mean Time or GMT). I hope this helps! Feel free to ask if you have any more questions.
