正说到冰雪,你会想起什么?是电影《冰河世纪》?还是南极、北极?今天,我们要讲的冰雪故事,是发生在6亿多年前地球上的一次极寒事件。与其相比,电影与南极、北极也不过是小巫见大巫罢了。冰与雪之歌"雪球地球",顾名思义,此时的地球普遍被冰雪覆盖,冷干的空气在苍凉的大陆上肆意驰骋,巨厚的冰层覆盖了广袤的海洋,当时全球的平均气 相似文献

本文以水的内生起源论的观点,概要地介绍了地球上水的起源和水圈的形成问题。地球上水的内生起源论认为,原始地球软流层排气作用是使包括有水汽在内的巨量易挥发性物质由地球软流层排升到地表的根本途径,也是规模宏大的原始海洋形成的基本物源。继原始海洋出现之后,大约在距今30～35亿年,由于地球上生命物质的出现、氮—氧大气圈的形成以及地壳开始分成相对稳定的槽、台区,导致了地球上局部地出现了淡水,并开始出现了巨大规模的水循环运动。从此,陆地地下水便作为天然水的一个循环运动阶段而出现了。 相似文献

数字地球与地球信息科学 总被引：9，自引：1，他引：8
本文从全球信息基础设施(GII)、地球空间数据基础设施(CSDI)、地球空间数据网络集成、科学计算可视化出发,阐述了数字地球面向社会大众与面向地球科学研究的两种不同的功能性构造体系的建立,并结合对于地球信息科学的理论、方法和技术的阐述,分析了数字地球与地球信息科学两者之间的关系。分析结果表明,如果将数字地球构造体系的建立与地球信息科学的研究结合起来,必将极大地推动2l世纪地球科学的发展。 相似文献
