The accumulated geophysical data for the Gulf of Mexico, combined with the known geology, make a number of maps possible which serve to define the modern geosyncline and provide some evidence as to its inception. The velocities and depths of interfaces observed in seismic reflection and refraction...
The boundary between the Earth's crust and mantle is called _. A. Moho discontinuity B. Gutenberg discontinuity C. Lehmann discontinuity D. Conrad discontinuity 相关知识点: 试题来源: 解析 A。解析:地壳和地幔之间的边界被称为莫霍面(Moho discontinuity)。古登堡面(Gutenberg discontinuity)是地幔和外核...
The Earth's Crust and Mantle presents the deformations of the Earth's crust, which are attributed to mantle currents. This book explores the gravity observations, which give indications about the way in which the masses in the Earth are distributed. Comprised of five chapters, this book starts...
The mantle of the Earth is _. A. the outermost layer B. between the crust and the core C. the innermost layer D. made up of the atmosphere 相关知识点: 试题来源: 解析 B。解析:地幔位于地壳和地核之间。选项A,地球的最外层是地壳;选项C,地球的最内层是地核;选项D,地幔与大气没有关系,大气...
A. It is as thin as the crust B. It is completely solid and has no movement C. It can flow slowly over a long period of time D. It has the same composition as the crust 相关知识点: 试题来源: 解析 C。解析:地幔在长时间内能够缓慢流动,这也是板块运动的动力来源之一。选项A,地幔比地壳...
A. The mantle B. The ocean C. The forest 相关知识点: 试题来源: 解析 A。解析:Mantle(地幔)位于地壳(the crust)和地核(the core)之间。海洋(the ocean)是地球表面的水体,森林(the forest)是地球表面的植被,它们都不在地壳和地核之间,所以B和C选项错误。
Continental and oceanic crust on the upper earth mantle 大陆地壳由多个层组成,其总体成分为中间值(SiO2 wt% = 60.6)。[5] 大陆地壳的平均密度约为 2.83 g/cm3 (0.102 lb/cu in),[6] 密度低于构成地幔的超镁铁质材料,后者的密度约为 3.3 g/cm3 (0.12 lb/cu in)。 大陆地壳的密度也低于大洋地壳,其...
