To determine where the coldest climates on Earth might be during the Northern Hemisphere summer solstice, we need to consider the distribution of solar radiation based on latitude. The Northern Hemisphere summer solstice occurs around June 21, when the North Pole is tilted towards the Sun, causing the Sun's rays to be more intense and concentrated in the Northern Hemisphere, while the Southern Hemisphere receives less direct sunlight.
-
Latitudes closest to Greenwich (around the equator) will experience relatively more intense solar radiation, not less.
-
Latitudes in the Southern Hemisphere, especially those farthest away from the equator (like Antarctica), would experience significantly less solar radiation during this time because they are tilted away from the Sun. This would be logical for temperatures to be significantly colder there during this period.
-
Tropical zone latitudes (0°–20°) actually receive the most intense solar radiation during the solstice, thus not leading to the coldest climates.
-
Latitudes 0°–20°S would still receive some solar energy during the Northern Hemisphere summer solstice, not none at all.
Considering all this information, the best response to indicate where the coldest climates might be during the Northern Hemisphere summer solstice would be:
Latitudes farthest away from the equator in the Southern Hemisphere would experience less-intense solar radiation, or none at all, during the Northern Hemisphere summer solstice, likely leading to the coldest climates on Earth during that time.
This response accurately reflects the expected climatic patterns across latitudes during the solstice.
