在高中地理教学中,地球运动的意义一直是学生学习中的一个难点,尤其是太阳高度问题。然而太阳高度的变化是有其自身规律的,我们在学习中只要真正理解其变化的规律,很多问题就可以轻松地解决。本文列举一些实例分析、说明太阳高度的变化规律,希望能对同学们有所帮助。一、关于太阳高度的日变化例1我国甲地中学生某一天观测太阳高度的变化,并将观测结果绘成图1,甲地学生发现此日测得的最高太阳高
In high school geography teaching, the significance of earth movement has been a difficult point in student learning, especially the issue of the sun’s altitude. However, the changes in the solar altitude have their own laws. As long as we truly understand the laws of their changes in learning, many problems can be easily solved. This article lists some examples to illustrate the changing law of the sun’s height, hoping to help students. I. Diurnal Variation of Solar Altitude 1 A high school student in a high school in a country observes the changes of the sun’s altitude on a certain day and plots the results as shown in Figure 1. A high school student found the highest solar elevation measured on that day
