地球的结构The Earth might seem like a rock ball, but it's actually made up of four very different parts. These parts are called the inner core(核心), the outer core, the mantle(地幔), and the crust(地壳).The inner core is at the center of the Earth. It's a hard ball of hot ...
The Earth's magnetic field pushes charged particles from the sun toward the North and South poles. The outer core of the Earth is made of iron which functions as a planetary magnet. 2. Which of the following is NOT a benefit of the Earth having a magnetic field?
The Internal Structure of the Earth:The Earth is made up of three main layers namely the crust, mantle, and core. The crust is the outer solid layer. The two inner layers are the mantle and core, respectively.Answer and Explanation: ...
varying function of pressure at pressures beyond 0.4 脳 10 6 million atmospheres in all three planets; ( c ) the outer core of the Earth is a high-pressure modification of ultrabasic rock; ( d ) each planet has an inner core chemically distinct from the matter in the outer core.doi...
Next comes the mantle, the thickest layer, which makes up about 67% of the earth's mass. Then there is a liquid outer core, including iron and nickel mostly. Finally there is an inner core, which is believed to be solid and mainly made up of iron-nickel alloy.It's difficult to ...
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, ...
It has a thin outer layer or crust where we live. And this includes our continents and the ocean floors. Then beneath that there's another layer called the mantle. And beneath that, is the Earth's core – over 6000km below the surface. ...
The planet Earth is made up of layers, some solid and some molten. Starting at the crust, take a trip to the Earth's inner core and learn about what each layer is made out of, until finally reaching the center of the Earth.
The Earth is composed of three layers: the crust, mantle and core. Crust(地壳) a thin layer of rock on the Earth's surface Mantle(地幔) hot, slow-moving rock below the crust and surrounding the core Outer core (外核) Inner core (内核) Core (地核) extremely hot, liquid iron mixed ...
