下图示意某内陆地区地形和气温分布。读图回答1～3题。1.该地区位于()A.北半球B.南半球C.低纬度D.中纬度2.a、b两条等温线气温相差约()A.3℃B.6℃C.5℃D.2.1℃3.x和z纬度相差2°,甲、乙、丙、丁四地年太阳辐射总量最高的是()A.甲B.乙C.丙D.丁解析:本题主要考查影响气温分布和太阳辐射总量的主要因素,图中的等温线和纬线都没有具体的数值,因此对学生的读图分析能力和逻辑推理能力要求较高。第1题:关于此题的答案,教辅书和互联网上有两种观点,一种观点认为应该是南半球,此观点认为同一海拔高度的甲、丙两地,甲的气温比丙高,所以甲的纬度比丙低,因此该地位于南半球。另一种观点认为应该是北半球,此观点认为同一海拔高度的甲、丙两地,甲的气温比丙高,是因为甲是山谷的阳坡,故该地位于北半球。
The figure below shows the inland terrain and temperature distribution. Read the answer to 1 ~ 3 questions. 1. The area is located in (A.) Northern Hemisphere B. Southern Hemisphere C. Low latitude D. Mid-latitude 2.a, b Two isothermal temperature difference between the temperature () A.3 ℃ B.6 ℃ C.5 ℃ D.2.1 ℃ 3.x and z latitude difference of 2 °, A, B, C, D four years the highest total solar radiation is (A) A B. B C. C D D. Analysis: The main test questions affect the temperature distribution And solar radiation total amount of the main factors, the figure isotherms and latitudes have no specific values, so the students ability of reading graph analysis and logical reasoning ability demanding. Question 1: There are two views on the answer to this question, supplementary books and on the Internet. One view is that the southern hemisphere should be considered. This view suggests that the temperatures in A and C at the same altitude are higher than those in C, A latitude lower than C, so the site is located in the southern hemisphere. Another view that should be the northern hemisphere, this view that the same altitude A, C, A temperature higher than C, because A is the sunny valley of the valley, so the site is located in the northern hemisphere.
