The Earth’s inner core is a huge metal ball,2,500kmwide. Made mainly of iron, the temperature of the ball is5,000°Cto6,000°C– that’s up to 6,000 times hotter than our atmosphere and scorching enough to make metal melt! The metal at the inner core stays solid because of the ...

he Earth's structure is made up of several layers. The crust is the outermost layer on which we live. Right beneath 1 the mantle (地幔), a warm, semi-liquid layer of rock. This is 2 by a thin shell of liquid iron that forms the outer core. 3 , there is a solid inner core, ...
The next layer in the earth's structure is the mantle making up about 80% of the earth's total volume. The mantle is similar to the core in that it has two layers. There is the inner mantle, which is about 1,600 miles thick, and the outer mantel, which is what bursts up as ...
This probably resulted in the formation of the earth's layers.然后,固态地球的内部变得炽热、熔融,引起某些物质上升到地球表面,其结果也许就形成了地层。 相关短句/例句 structure of the Earth's interior地球内部结构 1.It includes several research areas: the structure of the Earth′s interiors using ...

SAR mental imagery provides data on the exposed bedrock, layers of vegetation, and therefore the overburden found within the space. The dominant parameter determinant however a given rock unit can seem in a microwave radar image is its surface texture. Rock units break down differentially, leading...

We suggest that as a consequence, having shorter (36 nm) and wider (55 nm) hemidiscoidal PBS or even shorter rod-shaped PBS (height = 16 nm)25 became more advantageous in crown Cyanobacteria because they enable tighter packing of thylakoid membrane layers and higher energy transfer ...
