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。
题目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。本题考查地球内部结构。地幔是地球内部体积最大、质量最大的一层,其厚度远远大于地壳、外核和内核。
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。

Oceanic Crust: Thinner, about 5-10 km thick, primarily composed of Denser mafic rocks like basalt, diabase, and gabbro. It forms the ocean floors. The Mantle The mantle is the thickest layer of Earth, making up about 84% of the planet’s volume. It extends from the bottom of the crus...
Earth's Layers: The Earth is made up of four major layers: the crust, the mantle, the outer core, and the inner core. The crust is the thinnest portion, while the mantle is the thickest. Answer and Explanation:1 The hottest layer of the Earth is its innermost layer, the inner core....
The Earth is made up of several layers. Which layer is the thickest? A. Crust B. Mantle C. Core D. Ocean 相关知识点: 试题来源: 解析 B。解析:地球由地壳、地幔、地核组成。地幔是地球最厚的一层。地壳是地球最外层较薄的一层。地核分为内核和外核,也没有地幔厚。海洋不属于地球的结构层。

Mantle: The mantle is the next layer downwards towards the Earth’s core. It’s the thickest layer of the Earth at nearly 2900 km. It’s a semi-molten solid that can deform like a plastic. The top of the layer is hard like rock, but the bottom of the layer is beginning to melt ...
