三、岩石圈的研究目的和意义是什么?答:岩石圈的研究是一项基础研究,其主要目的在于:查明地壳的结构和构造,了解地壳的成因和演化.岩石圈的研究可分成以下课题:岩石圈结构与物理地质;地壳的应力状态;应变积累和释放;隆起和下沉;岩石圈板块的运动和内部变形,以及岩浆的生成、侵入和喷出.由于大陆上每一次构造活动均留下了它本身的痕迹,因此造成多次重叠的褶皱、断裂和块状构造.那么利用大洋地壳和上地幔
A: The research on lithosphere is a basic research, the main purpose of which is to find out the structure and structure of the crust and understand the genesis and evolution of the crust. The research of lithosphere can be divided into The following topics are addressed: lithosphere structure and physical geology, crustal stress state, strain accumulation and release, uplift and subsidence, lithospheric plate motion and internal deformation, and the formation, intrusion, and eruption of magma. As each continent on the structure Activities have left its own mark, resulting in multiple overlapping folds, fractures and massive structure. Then the use of oceanic crust and the upper mantle
