Earth, if cut in half, would be shown as layers, like a cake. It is made up of four main layers: the crust, the mantle, the outer core, and the inner core. Ingredients in Earth's layers include solid silicate-based rocks and liquid metals....
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?
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. ...
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 ...
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.
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 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 ...
the longest distance between two places on earth has been reduced to a flight of no greater than 24 hours, and our planet is becoming flat– one tap on a mobile phone connects us to the other side of the world in a split second...
