How are Earth’s inner core and outer core similar to each other and different from each other quizlet?
How are Earth's inner core and outer core similar to and different from each other? The inner core and outer core are both composed mainly of an iron-nickel alloy. However, the outer core is liquid, whereas the inner core is solid.
How is the outer core similar to the inner core of the geosphere?
Both the inner and outer cores consist primarily of iron and nickel. They're extremely hot, with temperatures ranging from 7200–9000℉ (4000–5000℃). The inner core is under intense pressure, which keeps it solid despite high temperatures. Outer Core: The outer core, which is liquid, is about 1300 miles (2092 km) thick.
Does the outer core and inner core have the same chemical composition?
The Earth has an outer core (liquid) and an inner core (solid). They are not chemically distinct from each other, but they are chemically distinct from the mantle. The core is mainly composed of nickel and iron.
What is the main difference between the two parts of the core?
Earth has a core, but this is really two distinct parts: the inner core and the outer core. Both parts of the core are made up of mostly iron and some nickel. The difference is that in the inner core, those minerals are solid and in the outer core, they're liquid.
Which of the following is a major difference between Earth’s inner core and outer core?
Which of the following is a major difference between Earth's inner core and Earth's outer core? The inner core is solid and the outer core is liquid.
How does the density of the Earth’s core compare to the other layers of the Earth?
The density increases in layers that are closer to the core of the Earth. The density increases in layers that are closer to the surface of the Earth.
What are the two common element present in the inner and outer core?
The solid inner core is made of mainly iron crystals with small amounts of nickel and heavier elements such as gold and platinum. The liquid outer core is a nickel iron alloy with small amounts of heavier elements.
What is the inner and outer core made of?
The inner core is mainly iron and is thought to be in the form of huge iron crystals. The outer core is liquid and is mainly an iron/nickel alloy. The core also contains small quantities of heavier elements. The inner core is solid with density up to 13 gm/cc, at the center.
How are the Earth’s layers alike and different?
Both the inner and outer core are made up of mostly iron and a little bit of nickel. The inner core is solid, while the outer core is liquid. This liquid flowing deep down below us is what produces Earth's electromagnetic current. And, it's pretty hot in the core – about as hot as the surface of the sun!
What is the difference of the inner and outer core?
The temperature of the inner core is far above the melting point of iron. However, unlike the outer core, the inner core is not liquid or even molten. The inner core's intense pressure—the entire rest of the planet and its atmosphere—prevents the iron from melting.
How do the inner core and outer core differ quizlet?
How do the inner core and outer core differ? The inner core is solid, whereas the outer core is liquid.
What is the main difference between Earth’s outer core and inner core quizlet?
What is the principal difference between the inner core and outer core? The inner core is liquid while the outer core is solid.
How does the density of the outer and inner core compare to the rest of the Earth?
The core is composed mostly of iron (80%) and some nickel. The density of the inner 'solid' core is between 9.9-12.2 g/cm3 and the outer core's density is between 12.6-13 g/cm3.
What do the outer and inner core work together to create for the Earth?
The Earth's magnetic field — created by the convection of hot liquid metal within the outer core — undergoes slight fluctuations roughly every decade. The inner core's rotation rate has also been shown to fluctuate on a similar timescale.
What is the composition of the inner and outer cores and is each one in solid or liquid form?
The core is the centre of the earth and is made up of two parts: the liquid outer core and solid inner core. The outer core is made of nickel, iron and molten rock….The core.

Is the inner core solid or liquid?
solid The core of the Earth is made up mainly of iron, in an outer liquid layer and an inner solid layer. The outer core is where the circulating conducting liquid generates the geodynamo, responsible for our magnetic field.
What are the inner and outer core made of and what makes them different?
The inner core is mainly iron and is thought to be in the form of huge iron crystals. The outer core is liquid and is mainly an iron/nickel alloy. The core also contains small quantities of heavier elements. The inner core is solid with density up to 13 gm/cc, at the center.
What is Earth’s outer layer similar to other than an egg?
The crust of the earth is broken into pieces, like the cracked shell of a hardboiled egg. The mantle of the earth is like the egg white, and the core of the earth lies in the center, like the egg yolk. The earth's brittle crust is broken into pieces that geologists call plates.
What characteristic of the outer core makes it unique among the layers of Earth?
The center of the Earth is made up of two layers, the outer core and the inner core. The outer core is the third layer of the Earth. It is the only liquid layer, and is mainly made up of the metals iron and nickel, as well as small amounts of other substances. The outer core is responsible for Earth's magnetic field.
What is the main difference between the inner and outer core of the Earth?
The temperature of the inner core is far above the melting point of iron. However, unlike the outer core, the inner core is not liquid or even molten. The inner core's intense pressure—the entire rest of the planet and its atmosphere—prevents the iron from melting.
Which of the following is a major difference between Earth’s inner core and Earths outer core?
Which of the following is a major difference between Earth's inner core and Earth's outer core? The inner core is solid and the outer core is liquid.
Which 2 elements are mainly found in the inner and outer core?
Unlike the mineral-rich crust and mantle, the core is made almost entirely of metal—specifically, iron and nickel. The shorthand used for the core's iron-nickel alloys is simply the elements' chemical symbols—NiFe.
Does Earth have 2 cores?
What we usually call our “inner core” is usually perceived as the centre of our planet, and its innermost layer. But turns out, the inner core has an inner core of its own! The traditional understanding of Earth puts forward four layers – the crust, the mantle, the outer core, and the inner core.
What are the internal layers of the Earth and how are they different from each other?
The inner core is solid, the outer core is liquid, and the mantle is solid/plastic. This is due to the relative melting points of the different layers (nickel–iron core, silicate crust and mantle) and the increase in temperature and pressure as depth increases.
Is the inner core hot?
Inner Core The inner core is a hot, dense ball of (mostly) iron. It has a radius of about 1,220 kilometers (758 miles). Temperature in the inner core is about 5,200° Celsius (9,392° Fahrenheit). The pressure is nearly 3.6 million atmosphere (atm).
What are 5 facts about the outer core?
Planet Earth
- Temperature. The Outer Core is about 4000-5000 degrees Celsius. The Inner Core is so hot it causes all the metal in the Outer Core to melt into liquid magma.
- Thickness. The Outer Core is about 2200 km thick. …
- Magnetism. Because the outer core moves around the inner core, Earth's magnetism is created.
What are the similarities of an egg to Earth’s internal structure?
The inside of the earth is layered something like an egg. Both have a thin, brittle shell. The crust of the earth is broken into pieces, like the cracked shell of a hardboiled egg. The mantle of the earth is like the egg white, and the core of the earth lies in the center, like the egg yolk.
What are the basic characteristics of the two parts of the Earth’s core?
The core is made of two layers: the outer core, which borders the mantle, and the inner core. The boundary separating these regions is called the Bullen discontinuity. Outer Core The outer core, about 2,200 kilometers (1,367 miles) thick, is mostly composed of liquid iron and nickel.
