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

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.

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

Inner core – High pressure from the other layers at the Earth center makes the inner core solid. Outer core – It is liquid because the temperature is high and there is not enough pressure to make it solid.

Why is it that the inner core is solid and the outer core is liquid Brainly?

Scientists know that the outer core is liquid and the inner core is solid because S-waves stop at the inner core. The strong magnetic field is caused by convection in the liquid outer core.

What is the difference between 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 inner core solid quizlet?

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. Again, it is very dense but because it is in its liquid form it is less dense than solid and forms the outer core. Rigid means that it is a solid.

Why is the 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. Answer 3: It turns out that many materials can be a solid at a higher temperature if the pressure is also higher.

Which of the following is the reason why inner core is solid while outer core is liquid given that both parts have the same chemical composition Brainly?

How is the outer core of the Earth different from the inner core?

How do we know the outer core is liquid?

Scientists figured out that the outer core must be liquid because S waves do not pass through it, but P waves do. The behavior of P and S waves also indicates that the inner core is solid. The speed of seismic waves also depends on the density of the material through which they are traveling.

What is the inner core and outer core made of?

The inner core is surrounded by this layer’s second part: a liquid, outer core that is about 1,355 miles (2,180 km) thick. This region is composed mostly of a nickel-iron alloy and its liquid material rotates faster than Earth’s surface (but in the same direction).
