Consider the following pairs:1. Winter Solstice: Day lasts for 6 month...
1. Winter Solstice: Day lasts for 6 months at the South Pole - Correct. During the winter solstice, the South Pole experiences continuous daylight for about 6 months, from approximately late September to late March.
2. Equinoxes: Sun's rays are vertical at the Tropic of Cancer on 21 March and 21 September - Incorrect. During the equinoxes, the sun's rays are vertical at the Equator, not the Tropic of Cancer. The equinoxes occur around 21 March and 21 September when day and night are of approximately equal duration worldwide.
3. Summer Solstice: Sun's rays fall vertically at the Tropic of Capricorn on 21 June - Incorrect. On 21 June, during the summer solstice, the sun's rays fall vertically at the Tropic of Cancer, not the Tropic of Capricorn.
4. Seasonal Changes: Longer days in summer lead to higher temperatures - Correct. In summer, longer daylight hours result in more solar energy being received, which raises temperatures. The sun is also more overhead, concentrating its heat on a smaller area, leading to warmer temperatures.
Thus, only one pair (Pair 4) is correctly matched.
