在野外的山上、河流边或道路旁,到处都可以看到各种各样、颜色各异的石头。石头,在地质学领域称为岩石,是地壳的主要构成部分。根据形成的原因,我们可以将岩石分为沉积岩、火山岩和变质岩三大类型。在地球表面分布最广的是沉积岩,约占地球表层岩石的70%。沉积岩又称水成岩,是地球表层岩石的风化物和火山喷发物经水流、冰川或风的搬运,沉积在水下或陆地表面,再经成岩作用而形成。沉积岩最典
In the wild mountains, riverside or the road, everywhere you can see a variety of different colors of stone. Stones, termed rocks in the field of geology, are the main components of the crust. According to the reason, we can divide the rock into three types: sedimentary rock, volcanic rock and metamorphic rock. The most widely distributed on the Earth’s surface is sedimentary rocks, accounting for about 70% of the Earth’s surface rock. Sedimentary rocks are also called diagenetic rocks. They are the weathered materials and volcanic eruptions of the Earth’s surface rocks that are transported by water, glaciers or winds, deposited on underwater or land surfaces, and then formed through diagenesis. Sedimentary rock the most classic
