Question

in december, a city in the southern hemisphere has warm weather all month long. what causes this to happen? the city experiences fewer hours of daylight. the city is experiencing a winter solstice. there is a high concentration of the suns rays in that region. the sun reaches its highest point in the sky during this month.

Explanation:

• When it is December in the Northern Hemisphere (winter), it is summer in the Southern Hemisphere. In summer, a region in the Southern Hemisphere receives a high concentration of the Sun's rays. This is due to the tilt of the Earth's axis. The Earth's axis is tilted at an angle of approximately 23.5 degrees. During December, the Southern Hemisphere is tilted towards the Sun. As a result, the Sun's rays are more concentrated over the Southern Hemisphere. This concentration of solar radiation leads to warmer temperatures.
• If a city had fewer hours of daylight (option 1), it would tend to be cooler (less solar energy input). The winter solstice (option 2) in the Southern Hemisphere would mean less solar radiation (since the winter solstice is the day with the least amount of daylight in a hemisphere). The Sun reaching its highest point in the sky (option 4) is related to the summer solstice, but the key factor for warm weather is the high concentration of solar rays which is a result of the Earth - Sun geometry (tilt) causing more direct sunlight in the Southern Hemisphere in December.

Answer:

There is a high concentration of the Sun’s rays in that region.
