B. It is between the crust and the outer core. C. It has no influence on volcanic eruptions. D. It is the coldest part of the E. arth. 相关知识点: 试题来源: 解析 B。解析:地幔位于地壳和外核之间。A选项,地幔并不是完全固体,它具有一定的可塑性;C选项,地幔中的岩浆活动对火山喷发有很大...
The thickest part of the Earth's _ is under the continents. A. crust B. mantle C. core D. hydrosphere 相关知识点: 试题来源: 解析 A。解析:地球地壳(crust)在大陆下面最厚。地幔(mantle)没有这种在大陆下最厚的情况;地核(core)是地球中心部分,与大陆下最厚无关;水圈(hydrosphere)是地球表面的水...
Earth - Core, Crust, Mantle: Earth’s outermost, rigid, rocky layer is called the crust. It is composed of low-density, easily melted rocks; the continental crust is predominantly granitic rock (see granite), while composition of the oceanic crust corres
Thermochemical mantle plumes are an integral part of Earth’s dynamic interior. More than 18 mantle plumes appear to originate from the deepest regions in Earth’s mantle. Mantle plumes influence surface processes, including continental break-up and mass extinctions. The location of two large low-...
Everything that happens at the surface of the Earth — the building of mountain ranges, the formation of ocean basins, volcanism and even changes in sedimentation patterns — is a response to events taking place within this part of the mantle. In addition, this is also the zone in which ...
二、 课文再现The Earth is actually comprised of three layers-crust, mantle and core. The thin layer of rock on the Earth's surface is crust. below 1.is mantle, and core is the2.(inner) part of the Earth. However. scientists haven't reached the mantle3.yet in that the intense ...
1. 地幔:依据震波速度之不连续性,可将地球内部分成(由上而下):地壳(EarthCrust),地幔(Mantle)及地核(Core)三带. 此分带与上述分圈不同. 软流圈大致相当于上部地幔,中心圈大致相当于下部地幔及地核. 2. 2. 斗篷:她在1998年装置作品斗篷(mantle)给我重重的一击. 现在美国迈阿密艺术博物馆. 看看那女人身后的...
Seismic images of Earth’s interior have revealed two continent-sized anomalies with low seismic velocities, known as the large low-velocity provinces (LLVPs), in the lowermost mantle1. The LLVPs are often interpreted as intrinsically dense heterogeneities that are compositionally distinct from the ...
主语中的top和solid并列修饰part of the mantle。C为该句的同义替换,故正确。 结果二 题目 The Earth comprises three principal layers: the dense, iron-rich core, the mantle made of (硅酸盐) that are semi-molten at depth, and the thin, solid-surface crust. There are two kinds of crust, a ...
Earth’s spin axis slowly moves relative to the crust over time. A 120-year-long record of this polar motion from astronomical and more modern geodetic measurements displays interannual and multidecadal fluctuations of 20 to 40 milliarcseconds superimpos
