在中学世界地理课本中,有几处提到大陆漂移、板块构造,裂谷以及火山和地震等方面的内容,其中有些现象是大家所熟习的,有些问题可能接触的不多,教学中可能存在一定困难。兹就我们学习过程中有关“板块构造学说”的一些粗浅体会,向同志作一概括介绍,供教学中参考。 In the Middle School World Geography textbook, there are several references to the contents of continental drift, plate tectonics, rifting and volcanoes and earthquakes, some of which are familiar to us, some of which may be of little or no contact with one another, may exist in teaching Must be difficult. Here are some of the superficial experiences we have learned about the “tectonic plate tectonics” and give a general introduction to the comrades for reference in teaching.
