what is the outer core density

At the center of the Earth lies the core, which is nearly twice as dense as the mantle because its composition is metallic (iron-nickel alloy) rather than stony. … The upper part of the mantle is cooler and more rigid than the deep mantle; in many ways, it behaves like the overlying crust.

What is the density of the crust?

about 2.7 grams per cubic cm
Continental crust is broadly granitic in composition and, with a density of about 2.7 grams per cubic cm, is somewhat lighter than oceanic crust, which is basaltic (i.e., richer in iron and magnesium than granite) in composition and has a density of about 2.9 to 3 grams per cubic cm.

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.

What is hotter inner core or outer core?

The inner core is indeed hotter than the outer core. However, the PRESSURE on the inner core is greater than the pressure on the outer core and the melting point of iron, the main constituent of the core, INCREASES as the pressure goes up.

What color is the outer core?

red
Remember what the colors represent: The inner core is yellow. The outer core is red. The mantle is orange and tan.

Why the density of Earth is highest?

The densest, heaviest elements always sink to the core during planet formation, and gravitation compresses that core to be even denser than it would have been otherwise. … Due to the power of its own gravitation, Earth is compressed by a few percent over what its density would have been without so much mass.

What is the outer core made of kids?

The outer core is the outer layer of the core that is made of liquid iron and nickel. Since it is a liquid, the outer core can spin, and it does. This spinning causes the entire planet to be magnetic (think of a refrigerator magnet).
