What are 2 differences between the inner core and outer core?

What are 2 differences between the inner core and outer core?

Main Difference: The main difference between the inner core and outer core of the earth is that inner core of the earth is the innermost layer of our planet, whereas outer core is the layer that surrounds the inner core.

Which of the following is a major difference between Earth inner core and earth 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 are the inner core and outer core similar?

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.

Which is solid inner core or outer core?

The inner core is solid, the outer core is liquid, and the mantle is solid/plastic. The metallic nickel–iron outer core is liquid because of the high temperature. However, the intense pressure, which increases towards the inner core, dramatically changes the melting point of the nickel–iron, making it solid.

What do the outer and inner core have in common?

The inner core is solid and is 90% iron, but the outer core is a liquid…and it’s a good thing it is! More on that later. The outer core is made of a mixture of iron and nickel, with smaller amounts of silicon and oxygen.

What is one similarity and one difference between the inner core and the outer core?

OThey are both a mixture of iron and nickel, but the inner core is solid and the outer core is liquid. Both parts of the core are much hotter than the boiling point of iron, its the very high pressure down there that stops them becoming gaseous iron and nickel.

Do the inner and outer core have the same chemical composition?

The inner core and the outer core are made up of similar stuff chemically (both are made mostly of iron, with a little nickel and some other chemical elements)–the difference between them is that the outer core is liquid and the inner core is solid.

What are 2 facts about the outer 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. As Earth spins on its axis, the iron inside the liquid outer core moves around.

What is in Earth’s 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).

Why is Earth’s inner core solid and outer core liquid?

Earth´s inner core and outer core are both made of an iron-nickel alloy. As you go deeper in the Earth both temperature and pressure increases. Although the inner core is very hot, it is solid because it is experiencing very high pressure. The pressure in the outer core is not high enough to make it solid.

Why is the Earth’s inner core solid?

The inner core is solid because it is made of very dense, or heavy, materials – like iron and nickel. Even though it is very hot, these materials don’t “melt” very easily, so they stay solid.

What is the difference between Earth’s core and outer core?

Key Differences The innermost part or layer of the earth is called as the inner core of the earth, whereas the layer that surrounds the inner core is known as the outer core of the earth. The earth’s inner core has a solid nature due to high pressure on it while the outer core of the earth is liquid in nature.

What are the two layers of the earth’s core?

The innermost layer is known as core and is further divided into two layers, i.e., the inner core and the outer core. The inner core is made up of a solid ball of iron and nickel due to high pressure in it whereas, the outer core is made up of liquid iron and nickel.

What is the temperature in the inner core?

Summary Table Inner Core Outer Core Innermost layer of Earth Surrounds the inner core Solid ball of iron and nickel Made of liquid iron and nickel Has a radius of 1,220 kilometers or 768 Approximately 2,300 kilometers or 1,400 Temperature estimated to be about 5,400 Hottest region is about 3,730-7,730 degr

What is the radius of the inner core of the Earth?

The inner core is located 6,371 kilometers (3,958 miles) deep beneath the surface, and its temperature is estimated to be about 5,400 degrees Celsius or 9,800 degrees Fahrenheit. The radius of the inner core is about 1,220 kilometers or 768 miles. What is the Outer Core of the Earth?
