Read the Schematic Diagram of Solar Illumination (the shaded part in the diagram indicates the night hemisphere, the arrow indicates the rotation direction of the earth, and the dotted line indicates the polar circle) and answer the following questions:

(1) south pole (1)?

(2) Winter solstice (1 min)? 23。 26 (1 min)? Limit day (1 min)

(3)24( 1)? 12( 1)

(4)9 ( 1) 24( 1)?

(5) At noon, the height of the sun is the highest on the tropic of Capricorn, and gradually decreases from north to south (2 points)? The days are short and the nights are long (1 min)

(1) This topic examines the polar top view. According to the clockwise rotation direction of the earth in the picture, it is judged as the top view of the south pole center.

(2) Extreme sunlight appears in the Antarctic Circle and its south, and the sun shines directly on the Tropic of Capricorn, which is the winter solstice in the northern hemisphere, and extreme sunlight appears in the Antarctic Circle and its south.

(3) Point D is located in the Antarctic circle, which is extremely daytime, and point A is located at the equator. The length of day and night is the same throughout the year, and the night time is 12 hour.

(4) According to the chart,: D is 0: 00 or 24:00 at the moment, and it is 9 o'clock at point C.

(5) This question examines the changes in the length of day and night and the height of the sun at noon. When the sun shines directly on the tropic of Capricorn, the distribution law of solar height with latitude at noon decreases from the tropic of Capricorn to the north and south sides respectively. The days in Guangxi are shorter than the nights.
