What dense center of earth is made of solid iron and nickel?
The dense center of the Earth is known as the core, and it is divided into two parts: the inner core and the outer core. The inner core is mainly composed of solid iron and nickel, while the outer core is a liquid layer made up of molten iron and nickel.
What is the 2 layer of earth?
Well, it starts off like this: It starts at thesurface. then the crust. then the mantle. then the outer core and last, the inner core.
Is the earth made up off nickel?
Outer core - Predominantly liquid iron and nickel. Inner Core - Nobody knows, until they dig to the center of the earth. If anyone tells you otherwise, then they're lying. We need facts, not ridiculous beliefs from "experts".
What are the characteristics of the earths outer core?
The Outer Core is made up of a liquid iron and nickel alloy. This creates the earth's magnetic field. It is in a liquid form due to the intense heat given off by the inner core (which is 5500C due to the decay of radioactive elements such as uranium inside) It is roughly 2300 metres thick.
What are some physical characteristics of the earths outer core?
The Outer Core is made up of a liquid iron and nickel alloy. This creates the earth's magnetic field. It is in a liquid form due to the intense heat given off by the inner core (which is 5500C due to the decay of radioactive elements such as uranium inside) It is roughly 2300 metres thick.
What is earths core made out off?
Iron (85%) and Nickel (5%). 10% Oxygen, Silicon and smaller amounts of siderophile elements.
What areas under the earth do earthquake waves bounce off?
Every discontinuity inside the earth can reflect seismic waves. These occur between major layers (crust, mantle, outer core, inner core) and are named after scientists (Mohorovicic and Gutenberg for example).
How earth behaves as an electromagnet?
Because the inner core of Earth is a solid sphere suspended in the gravitational center of the liquid outer core. Both cores are an alloy made up of mainly nickel and iron. This alloy is conductive and the inner core is spinning at a different rate in the outer core. This difference in angular momentum creates a huge electric dynamo, which in turn creates a strong magnetic field. If and when the core of the earth completely cools to a solid the dynamo effect will cease, and our magnetic field will collapse. If there is any atmosphere that remains at this time, it will be boiled off into space by our suns solar wind. The water will eventually follow the way of the atmosphere and the surface of earth will begin to look like the surface of Mars.
What is earths liquid?
The only liquid layer of Earth is the outer core, composed of liquid iron and nickel. Deep in the Earth's interior is an iron and nickel core. The center of that core is solid, but there is a layer a thousand miles or more think that is liquid. Above the core is mantle material that is not necessarily considered liquid, because it is so viscous. Earth has an outer solid crust.
What are some of the differences and similarities between the mantle crust and the core?
Crust- The crust is the thinnest layer of the Earth and is from 0-50 km deep. The crust is not one whole rather it’s separated into different pieces called the plates. The earth’s crust is also the lightest layer, it’s rocky and rigid. Mantle- The mantle of the Earth is the largest and the layer that takes up most of the space-2900 km deep. The mantle is mostly made up of magma and molten rocks because of the heat given off by the core. Core- The core is the hottest, second biggest and inner most layer of the earth. It mainly consists of solid iron and nickel. The heat in the core is what causes the mantle to be in fluid form. The core is really hot heating up from 3500 C to more than 6000 C Compare- The similarities of the three types of layers are- The three layers help to support the structure of the Earth. The mantle and the core are really hot and the two biggest layers. Both the Mantle and crust are solid. Contrast- The difference is that the crust of the earth is made out of soil and rocks while the mantle consists of lava and molten rocks, finally the core is made up of solid iron and nickel. All the layers are made up of different natural materials.
What have happened to the original rocks?
They were recycled by the Earth core or blown off Earth by meteors
Where is thermal energy made?
thermal energy is made in numerous places, such as the earth's core, your body and space heaters. any where you feel heat is giving off thermal energy.
