百度试题 结果1 题目Which layer of the Earth is the thickest? A. Crust B. Mantle C. Inner core D. Outer core 相关知识点: 试题来源: 解析 B。本题考查地球结构的知识。地幔是地球中最厚的一层。地壳相对较薄,内核心和外核心也不如地幔厚。
How far is the Earth's outer core from the crust? What layer lies directly above the Earth's inner core? What are the properties of Earth's inner core? How wide is the Earth's mantle? What material makes up Earth's inner core?
Mantle: It lies below the crust and is up to 2900 km thick. It consists of hot, dense, iron and magnesium-rich solid rock. Core: It is the center of the earth and is made up of two parts: the liquid outer core and solid inner core. The outer core is made of nickel, iron and...
Inner Core: The Inner Core is the layer beneath the mantle and forms the earth's center with a radius of about 122000M. A high temperature of 5700 K is almost close to the sun's temperature. The inner core's composition is Iron and nickel alloy and other elements. Answer and Explanati...
“We sort of think the outer core is stirring up the inner core, but the mantle’s trying to keep it aligned — maybe that’s why it’s oscillating,” he said. The latest discoveries about the inner core have fueled vigorous disagreements among the world’s top Earth scienti...

The traditional view of the Earth’s interior has the crust (where we live), the upper and inner mantle, the outer core, and the inner core; wrapped around each other like layers of an onion. But now textbooks will need to be revised. It turns out there’s an inner,innercore. ...
data on the viscosity of iron as the inner core surface manifestation of a thermally-driven flow, with a positive correlation among compressional speed and attenuation and temperature. Although the outer-core convection controls the heat flux across the inner core boundary, the internally driven ...
Surprise! Earth has a secret hidden layer. Scientists are trying to chart this mysterious boundary deep inside Earth's inner core.
