The Earth has different layers. The outer layer is called the crust. Which layer is below the crust? A. The mantle B. The core C. The atmosphere D. None of the above 相关知识点: 试题来源: 解析 A。地壳下面是地幔。B 选项地核在更深处;C 选项大气层不是在地球内部。
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。
这个句子其实是:an opening in the earth's crust which hot or melted rock and steam erupt from, erupt from“从……喷射出”的意思,from是不能被省略的,因为一般陈述句语序是“hot or melted rock and steamerupt froman opening in the earth's crust”, ...
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。
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。反馈 收藏 ...
Which of the following is caused by the movement of the Earth's crust? A. Volcano B. Tides C. Typhoon D. Thunderstorm 相关知识点: 试题来源: 解析 A。本题考查自然现象的成因。火山(Volcano)是由地壳运动引起的。潮汐(Tides)主要是由于月球和太阳对地球的引力作用。台风(Typhoon)是一种大气环流现象...
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。
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,地幔比地壳厚很多。选项B,地幔不是完全固态且静止的...
百度试题 结果1 题目Which layer of the Earth is the thickest? A. Crust B. Mantle C. Core 相关知识点: 试题来源: 解析 B。解析:在地球的结构中,地幔是最厚的一层,地壳相对较薄,地核虽然重要但不是最厚的,所以答案是B。反馈 收藏
