The continental crust has ultimately been extracted from the mantle and knowledge of its composition is therefore fundamental to an understanding of the ch... BL Weaver,J Tarney - 《Nature》 被引量: 724发表: 1984年 The Composition and Evolution of the Continental Crust: Rare Earth Element Evide...
Biomineralization is the process by which living organisms acquired the capacity to accumulate minerals in tissues. Shells are the biomineralized exoskeleton of marine molluscs produced by the mantle but factors that regulate mantle shell building are st
The passage is primarily concerned with discussing 选项: A、the composition of Earth's mantle B、how the Hawaiian Islands were created C、what causes Earth's surface plates to move D、two different mechanisms by which volcanoes are formed ...

What is the composition of the crust under the continents? Continental Drift: The continents as we know them are changing, but at a rate far too slow for humans to perceive as they are floating about on the Earth's mantle. This movement of the Earth's crust results in volcanoes, tsun...
Geochemical picture of the mantle 1.The mantle is depleted in those elements that are found to be concentrated in crust, hydrosphere and atmosphere, relative to the original composition of the mantle. 2.Some material from crust, hydrosphere and atmosphere is re-injected into the mantle. 3.The...
