Urgent High School Geography Problems Canopy growth direction Sunrise direction

1.The flag-shaped canopy on the island of Hawaii generally points to the southwest

The latitude of Hawaii Island is about 20°N, and it is affected by the northeast trade winds all year round, and the buds on the windward side of the trees on the island are damaged by the wind, so there are no branches on the windward side. The buds on the leeward side survive more because they are less affected by the wind, and form a flag-shaped tree! Therefore, the canopy of flag trees on the island generally points southwestward.

2.What seasons correspond to spring, summer, autumn and winter in the Northern Hemisphere and in the Southern Hemisphere? [Autumn, winter, spring and summer].

This question is easier, when it is summer in the northern hemisphere, the sun shines directly on the northern hemisphere, and the southern hemisphere is winter; When the sun shines directly on the southern hemisphere in winter in the northern hemisphere, it is summer in the southern hemisphere; The opposite is true for spring and summer in the northern and southern hemispheres.

3: How to determine the direction of sunrise in a certain place?

We must first know the geographical location of Kunlun Station, which is on the Antarctic continent, with a latitude and longitude of 80 degrees 25 minutes 01 seconds south latitude and 77 degrees 06 minutes 58 seconds east longitude.

1. [The sun shines directly on the equator].

Rule 1: On the equinox of spring and autumn, the sunrise and sunset directions all over the world rise from the east and set from the west except for the north and south poles.

2. [The sun shines directly on the Northern Hemisphere].

Rule 2: When the sun shines directly on the Northern Hemisphere, the sun rises from the northeast and sets from the northwest except for the polar day and polar night regions around the world, and the closer the latitude of the direct sun point is to the Tropic of Cancer, the more northerly the sunrise and sunset will be; The higher the latitude, the more northerly the sunrise and sunset.

3. [The sun shines directly on the Southern Hemisphere].

Rule 3: When the sun shines directly on the southern hemisphere, except for the polar day and polar night regions, the sun rises from the southeast and sets from the southwest, and the closer the latitude of the direct sun point is to the Tropic of Capricorn, the more southerly the sunrise and sunset will be; The higher the latitude, the more southerly the sunrise and sunset.

From the above analysis, it can be seen that the orientation of sunrise and sunset in various places depends not only on the latitudinal position of the direct sun point, but also on the local latitudinal position. The latitudinal position of the direct sun point determines whether the sunrise and sunset are southernerly or northerly, and how far southward or northerly they are. It is not difficult to see that on the same day, the orientation of sunrise and sunset observed around the globe is consistent in the direction of south or north, regardless of the position of the hemisphere.

The level of latitude will affect the degree to which the sunrise and sunset are in a southerly or northerly direction. When the sun shines directly in the Northern Hemisphere, the higher the latitude, the more northerly the sunrise and sunset; When the sun shines directly in the Southern Hemisphere, the higher the latitude, the more southerly the sunrise and sunset will be.

Hope it helps!

1.Wind direction (not so sure, it feels like it).

2.[Autumn, winter, spring and summer].

3.Looking at the shadow of the sun, the northern hemisphere cannot face south, (do not look at the special circumstances, excluding the area within the Tropic of Capricorn) seems to rise in the east, regardless of the northern and southern hemispheres, but only know that Venus is the sun in the west.

Question 1, when the sun shines directly on the Northern Hemisphere, the sunrise in the northeast and the sunset in the northwest in various parts of the northern hemisphere Basic knowledge needs to be memorized. BE is in the Northern Hemisphere, so the summer solstice is sunrise in the Northeast.

Question 2. At 3:20 a.m. Beijing time on July 14, the time converted to Rio de Janeiro (22°57 s, 43°12 W) is about 3:20 11 hours At 16:20 on the 13th, in the afternoon, the sun was moving westward in the city.

The third question, the symmetry point, is 22 days apart from July 14 to June 22, so the other time is June 22 22 days around June 1.
