Subtitle 1: If there is no obvious seasonal change in the river runoff in the figure, the following statement is incorrect ()
A. The seasonal variation of salinity at point A is very obvious
B. The river is located in the temperate marine climate zone
C. Cold current flows along the coast of the mainland
D. The area shown in the figure is located in the Southern Hemisphere Topic 2: At 1:30 a.m. Beijing time on November 3, 2011, "Tianguan 1" and "Shenzhou 8" achieved their first docking, so the following statement is correct ()
A. Xiaohua in place B watched the live broadcast at 12:30 on November 3
B. On that day, Wuhan sunrise in the northeast and sunset in the northwest
C. At this time, the sun height decreases from the point located at (11 ° S, 83 ° W) to the surrounding
D. At noon in Beijing this day, the shadow length of a building is short and will gradually increase
Best answer:
Subtopic 1: A
Subtitle 2: C
Answer analysis:
Subtitle 1: Since there is no obvious seasonal change in the river runoff in the figure, it indicates that the precipitation in this area is relatively uniform in the year. Combined with its latitude location, it is known that it is a temperate marine climate. The figure is located in the west bank of the 40 ° - 60 ° continent in the southern hemisphere; According to the distribution law of ocean current, there is cold current passing by the coast; The salinity of Jiadi is mainly affected by surface runoff, with little seasonal variation.
Subtitle 2: 1:30 am Beijing time on the 3rd, and 12:50 am local time on the 2nd; This is the winter half year of the Northern Hemisphere. On that day, Wuhan sunrise in the southeast and sunset in the southwest; According to the information in the question stem, at this time, the direct sunlight point is roughly located at (11 ° S, 83 ° W), and the sun height decreases from the point located at (11 ° S, 83 ° W) to the surrounding; At this time, the sun directly shines on the southern hemisphere, and the shadow length of a building at noon in Beijing is longer and gradually increases along with the southward movement of the direct sunlight point.
Test core:
Globe: people imitate the shape of the earth and reduce it in a certain proportion to make a model of the earth - the globe.
(1) The earth axis - the imaginary axis of the earth's rotation (2) The poles - the earth axis passes through the earth's center and intersects the earth's surface at two points. The point pointing to the North Star is called the North Pole; The opposite of the North Pole is called the South Pole.
(3) Equator - a large circle on a globe that is equidistant from the north and south poles.
Longitude and latitude lines: Longitude and latitude lines are drawn on the globe and map in order to determine the position and direction on the earth. There is no longitude and latitude line on the ground. The line connecting the north and south poles is called longitude. The line perpendicular to the longitude is called the weft line. A weft line is a circle of unequal lengths. The longest latitude line is the equator. Because longitude indicates the north-south direction, it is also called meridian. According to international regulations, the longitude passing through the original site of the British Greenwich Observatory is called the 0 ° longitude, also called the prime meridian. On the earth, the longitude indicates the north-south direction, and the latitude indicates the east-west direction.
(1) Latitudinal line: a circle circling the earth in the east-west direction.
(2) A line connecting the north and south poles and perpendicular to the latitude line.
