The observed correlation between the decade variations in the earth's rotation and geomagnetic secular variation probably can be accounted for by electromagnetic core-mantle coupling as suggested by Bullard long ago. The new observations, combined with a simplified earth model, provide some indications ...
The outer core refers to the liquid layer of the Earth's core, located between the inner core and the mantle. It is primarily composed of iron with some lighter elements, and its high electrical conductivity allows for the generation of a magnetic field. ...
Earlier origin for earth's center: innermost core formed soon after planet did, study finds The resulting PCB permits direct die-attach of high-power RF die, such as GaA and GaN devices, through a cavity in the outer core layers directly to the thermal layer below, and then wire-bonding ...

Which layer of the earth is the thickest? A. The crust. B. The mantle. C. The outer core. D. The inner core. 相关知识点: 试题来源: 解析 B。本题考查对地球结构的了解。地幔是地球最厚的一层。选项 A 地壳较薄,选项 C 外核和选项 D 内核都没有地幔厚。
To answer this question, I survey variants of hard sphere liquid theory by applying them to the Earth’s outer core to determine which of them explains wavespeeds in the outer core best. The variants explored here are the Carnahan-Starling hard sphere model, the Mansoori-Carnahan-Starling-Lela...
题目Which layer of the Earth is the thickest? A. The crust B. The mantle C. The outer core 相关知识点: 试题来源: 解析 B。解析:Mantle(地幔)是地球最厚的一层。Crust(地壳)相对较薄,Outer core(外核)虽然也是地球内部的重要部分,但厚度不及地幔,所以A和C选项错误。
