Answer the questions about the direction of sunrise in detail!

Under the irradiation of sunlight, objects always have their own shadows (except in the case of direct sunlight), and the orientation of the shadows is related to the orientation of the sun. At the same time, at different latitudes, the direction of the sun is different; At different times in the same latitude, the sun faces differently. Therefore, the direction of the shadow has day and night and seasonal changes. 1. The sun shadow direction of different solar terms in the same region (taking the northern hemisphere as an example) (1) The sun shadow direction in the equatorial region. In the equatorial region, the sun rises and sets vertically all year round, and the latitude of the rising and setting direction of the sun is the latitude of direct sunlight. & lt/SPAN>。 & lt/p & gt； Equatorial sunrise direction Sun direction Sun direction Sun direction Sunset direction Sun shadow direction Summer to southwest due north 66 34' due south northwest spring and autumn equinox due west zenith 90 due east winter to southeast northwest due south 66 34' due north southwest northeast (2) The direction of the "bisector" sun shadow on the Tropic of Cancer is the latitude from equator to polar day and night, and the higher the latitude, the direction of the sun rising and setting. Tropic of Cancer Sunrise Azimuth Sunset Azimuth Sunset Azimuth Sunset Azimuth Sunset Azimuth Sunset Azimuth 90 No Northwest Southeast Vernal Equinox Due East due West due South 66 34' Due North due East Winter to Southeast due Northwest due South 43 08' Due North Southwest Northeast (3) The direction of "bisection" of the sun shadow on the Arctic Circle begins to appear on extreme days, and the sun rises and falls in due north. Sunrise direction in Arctic Circle Sun direction Sun direction Sunset direction Sun shadow direction Summer to Sun due north due south 46 52' vernal equinox and autumnal equinox due east due west due south 23 26' due north due west due east winter to solar night without sunrise and sunset (4) The direction of sun shadow in Arctic is during the extreme day, in the Arctic, because the eye horizon of the sun is always parallel to the horizon on Sunday, it is simultaneous. At the vernal equinox and autumnal equinox, the poles are equally divided day and night. At this time, the height of the sun is 0, just below the horizon.

Arctic sunrise azimuth, sun shadow azimuth, sun shadow azimuth, summer solstice, no due south 23 26', due south at the vernal equinox, due south 0 due south at the winter solstice, no sunrise and sunset at night, and sun shadows in different regions of the same solar term (taking the southern hemisphere as an example) (1) When the sun shadows in different regions of the southern hemisphere face the vernal equinox, the sun shines directly at the equator, and the world is equally divided day and night. That is, at the vernal equinox, the height of the sun is reduced from 90 to 0, the sun shadow faces noon, the sun shadow faces sunset, the sun shadow faces due east and west of the equator, the zenith is 90 without due west, the tropic of Capricorn is due north 66 34' due south and due west, the Antarctic circle is due east and due west 23 26' due south and due west, and the southeast pole is due north and due north (2 The sun in the equatorial region rises vertically from due east to north at 23 26' and sets vertically from due west to north at 23 26'. The higher the latitude, the greater the deviation from due east to due north. In the extreme night, the sunrise and sunset just shrink to a point, which is located in the north.

Sunrise azimuth to sun azimuth in summer, shadow azimuth and sunset azimuth 66 34' due south, northwest, southeast, due north of tropic of Capricorn, northeast, southwest, northeast, southeast, due north of tropic of Capricorn 43 08' due south, and there is no sunrise and sunset in Antarctic polar night (3) The sun points directly at tropic of Capricorn in different parts of the southern hemisphere from winter to sun, and polar days appear in Antarctic circle and its interior. The higher the latitude, the greater the angle of sunrise and sunset due east and south, and the sunrise and sunset are due south when they reach the polar circle. Sunrise azimuth to sun azimuth and sunset azimuth in winter Sun azimuth 66 34' due north, southeast, southwest, northeast, tropic of Capricorn, southeast, northwest, zenith 90 without southwest, northeast, Antarctic circle due north, 46 52' due south, due north, south pole, no sunrise and sunset, and the sun is all located at 23 26' due north.
