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。
Of these 250 are said to be plentifulon the earth. Only 25 minerals are found on the earth's surface and in most surface rocks.Most of them are made of only eight elements.Eight Major Elements of the Earth's Crust found in ... ...
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, ...
[1](b)Using the information in Figure 1, suggest the most common compound found in the Earth's crust.[1](c)Using your knowledge of the reactivity series, suggest the relationship between the year of discovery of the metals and the reactivity of the metals in Table 1...[1](d) Using ...
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...
The outermost surface of the Earth is called the lithosphere, or crust. This rigid layer contains both the oceans and landmasses. Most elements are found in only trace amounts within the earth's crust, but several are abundant. Elements and Compounds ...
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 pe...
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
It’s something about strontium isotopes in plants and soils, the teeth of rodents wherever he strolled, volcanic deposits, ancient remains of the earth’s crust, and Kik’s DNA. It probably would take a hundred pages to describe the processes used to determine facts about Kik’s remarkable...
