2、 。中部有地下水丰富的 盆地。（2）河流：发源于大分水岭的 河是澳大利亚最长的河流，注入 。3、澳大利亚的气候（提示：读图8.38）（1）主要气候类型有：61569; 、61570;_、 61571; 、 。（2）气候分布特点：至西向东呈 分布。4、澳大利亚特有动物有很多，主要有： 、 、鸭嘴兽、鸸鹋等，其中登上澳大利亚国徽的是 、 。澳大利亚因此被三合作探究探究主题：为什么只有在澳大利亚才有如此多的古老生物呢？材料：在两亿年前的中生代时期，由于板块的运动使大陆开始分裂、漂移。其中美洲漂移最快，最慢的是澳大利亚，这是个漫长的过程。大约在6500万年前，澳大利亚大陆与其他大陆彻底地分开。由于长期

3、孤立于南半球的海洋之中，这里自然环境比较单一，生物演化十分缓慢。许多古老的生物种类保留至今，它们是这块古老大陆演变的见证。（1）大陆漂移说：阅读材料，澳大利亚大陆大约在什么时候已与其他大陆分离？（2）独特的位置：观察78页图8.34，澳大利亚这个国家独自占有澳大利亚大陆，是世界上独占一块大陆的国家。澳大利亚大陆长期地存在于南半球的海洋上，这对生物的进化会产生什么影响？（3）和澳大利亚大陆一样，长期处于孤立状态的南极大陆为什么特有生物却很少呢？四巩固提升1、关于澳大利亚的叙述错误的是（ ）a大洋洲面积最大，人口最多的国家b世界上唯一独自占有一个大陆的国家c全国最大的河流是墨累河d西部是南北纵列的
