Why is the inner core solid and the outer core liquid quizlet?

The core is very dense and composed mostly of Iron and Nickel. The Earth’s Inner core is solid because there is so much pressure exerted that it can only exist in the solid form. The outer core is liquid iron and nickel. Rigid means that it is a solid.

What evidence supports the Earth having a solid interior core and liquid outer core?

Density calculations show that Earth’s core is metal. Seismic waves show that the inner core is solid and the outer core is liquid. Metallic meteorites and the magnetic field are also clues about the makeup of the core.

What is the main difference between the inner core and outer core?

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.

Why is the outer core the only layer in Earth that is molten group of answer choices?

Earth’s Outer Core The outer core is the liquid largely iron layer of the earth that lies below the mantle. Geologists have confirmed that the outer core is liquid due to seismic surveys of Earth’s interior.

Why is the inner core solid and the outer core liquid?

pressure is 3,000,000 times more than at sea level in the Earth’s core. The pressure is so great that the metals are squeezed together and they can’t be a liquid. The outer core can be a liquid because at a certain depth, the pressure of the earth above it is not enough to keep it from melting.

Why is the core of the earth 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. Answer 3: It turns out that many materials can be a solid at a higher temperature if the pressure is also higher. Similarly, is Earth’s core solid or liquid?

Is the innermost part of the earth solid?

But the innermost part of the Earth, the core, has been surmised to be solid, without clinching seismic evidence, until now.

What makes up the center of the Earth?

At the center of the Earth is the core, which has two parts. There is a solid inner core composed primarily of iron with a radius of about 1,220 km and a liquid outer core composed of a nickel-iron alloy. The inner and outer core are essentially composed of the same material but pressure makes all the difference.
