在新编高一地理教材第三单元《海洋环境》中《海水运动》一节讲述了洋流的形成,其中密度流的成因是一个难点,为了让学生理解其成因,明确其分布,我设计了“密度流成因”演示实验,并分析如下。1密度流原理及演示实验密度流是由于海水密度在水平方向上的不均匀分布引起等压面倾斜 The formation of ocean currents is described in the section “Marine Environment” in the third edition of the GaoYi Geography Textbook “Marine Environment”. The cause of density flow is a difficult point. In order for students to understand their causes and clarify their distribution, I designed The “Generation of Density Flow” demonstration experiment was analyzed as follows. 1 Density flow principle and demonstration experiment Density flow is caused by the uneven distribution of seawater density in the horizontal direction
