答案:D more>> most分析:考点是最高级的使用;由于有 Of all the elements 对比较范围进行了限定,因此要用最高级,将 more 改为 most;全句也是一个倒装结构,正常的语序是 Oxygen is known to be the most common of all the elements in the Earth’s crust.翻译:在地壳的所有元素中,氧被认为是最多的。
This is a table that shows the elemental chemical composition of the Earth's crust. Keep in mind, these numbers are estimates. They will vary depending on the way they were calculated and the source. 98.4% of the Earth's crust consists ofoxygen, silicon, aluminum, iron, calcium, sodium, ...
Compared with the present, the distribution of elements in the Earth's interior in the early days was ___. A. more uniform B. more scattered C. less complex D. more concentrated in the crust 相关知识点: 试题来源: 解析 A。解析:和现在相比,早期地球内部元素分布更均匀。在地球形成早期,物质...

About 98 per cent of the total crust of the earth is composed of eight elements like oxygen, silicon, aluminium, iron, calcium, sodium, potassium and magnesium, and the rest is constituted by titanium, hydrogen, phosphorous, manganese, sulphur, carbon, n
The earth's crust is defined as the solid outer shell of the earth,and delimited fromthe top,the earth rigid surface,down deep to the Mohorovicic discontinuity.By such adefinition,the abundance of chemical elements in the crust is recalculated by a newmethod,named the regional geochemical meth...
Figure 1 shows theabundance of elements in Earth’s crust. Figure 1. The Elite Eight Elements. The elements are listed along the x-axis and the percentage is on the y-axis. All numbers are approximate. Oxygen is just below 50 percent; silicon is just about 25 percent. Calcium is 5 per...
The elements in the outermost surface of the Earth, the crust, are found mostly in trace amounts. Oxygen, the most abundant element in earth's crust, is nearly half of the crust's mass. Other abundant elements are silicon, aluminum, iron, calcium, sodiu
Heavy elements such as iron, nickel pooled to form the Earth's core; oxygen, silicon, aluminum, slightly lighter elements remain in the surface to form a crust. Intense volcanic activity in the Earth release of lighter gas to form different from today's early at 翻译结果2复制译文编辑译文...
The evaluation of the abundances of chemical elements in the Earth’s crust is a pivotal geochemical problem. Its first solutions in the early 20th century formed the empirical groundwork for geochemistry and justified concepts about the unity of the material of the Universe, the genesis of the...
