人们吃西瓜总喜欢把西瓜一分两半,人们去研究分析地球上的某种因素时,也喜欢把地球分成两个半球,当然各种半球的划分各有所用,各有标准。现分述如下: 南半球与北半球以赤道为分界线,赤道以北为北半球,赤道以南为南半球。南北半球冬、夏气候正好相反,即北半球过夏天、南半球则过冬天。在北半球内,陆地占39.3%,主要包括亚洲的大部分、欧洲、北美洲、南美州北部和非洲的北半部;海洋占

When people study and analyze certain factors on the earth, they also like to divide the earth into two hemispheres.
