What has a seismology taught us about the earth interior?
Through Seismology, or through studying earthquakes, we have been able to find that the Earth's interior is composed of three layers: Crust, Mantle and Core. The core is further divided into outer core and inner core.
What roll does the layers of the earth play in life?
If there wasn't a boiling hot inner core, then the Earth would implode, or cave in on itself. If there wasn't a mantle, there would be no shield protecting us from Earth's fiery core. And if there wasn't a Crust, then what would you be standing on? Nothing!
Is the inner core of the earth is made up of solid iron and nickel and is approximately 1200 kilometers in diameter?
Yes. Because the inner core is made out of nickel and iron (two of the three magnetic elements, the other being cobalt), it rotates and generates Earth's magnetic field, which protects us from solar radiation in outer space.
Why is earths outer core important?
A2. The Inner Core of the Earth is composed of nickel and iron and other heavy elements, many of which are radioactive. Lord Kelvin (of temp fame) studied this problem of the source of the earth's internal heat, but as radioactive generation of heat was yet to be discovered, his calculations were in error.The Inner Core has a temperature of about 5800 deg C, similar to the surface of the Sun! Because of the pressure, the Inner Core of the Earth is solid.The Outer Core has a similar composition, but, under less pressure, it is liquid.And above this again is the magma, which drives tectonic plates, volcanoes and the like. Electrical currents generated in the cooler magma and running roughly parallel to the equator, are responsible for most of Earth's magnetic field.[BTW, his given name was William Thomson, and upon his elevation to the peerage he chose the name of the small stream, the Kelvin that runs by Glasgow University, as his peerage name. ]
What is the outer core'?
The outer core is a layer of molten metal that surrounds the inner core. The outer core lies at a depth from 2900 km to 5150 km. It's composed of liquid iron and nickel along with small amounts of lighter elements, with temperatures ranging from 4,000 degrees C to 6,100 degrees C near the boundary with the inner core.The Earth's outer core:is composed primarily of liquid iron and nickelextends from a depth of 1,806 to 3,219 miles from the surfacecomprises 30.8 percent of Earth's masstemperatures range from 7,200-11,000 Fcontrols Earth's magnetic field which protects us from the sun's solar windsis in a liquid state
Is the earth's inner core solid?
Yes the refraction path of the p-wave tells us that the earths inner core is solid.
How do the ozone layer affect earth?
The core protects the Earth by making a magnetic field and the ozone so there can be life on Earth. The mantle keeps the core moving and hot. The Crust protects the core like a hard outer shell. the inner core acts as a energy room for the earth.
Facts about the earths core?
The Inner core is the last layer in the earth surface and is what gives the earth its magnetic field. the outer core is liquid nickel and iron but the inner core is 80% solid iron and 20% solid nickel,gold,platinum, and uranium. the inner core is so far in the earth surface we can not reach it we can tell its there by seismic waves.

Is the inner core of earth solid and made primarily of iron?
No. The SUN's core is Hydrogen and Helium. The EARTH's core is Iron and Nickel.

What layer of the earth is the life layer?
The kayer that protects life on Earth is the Crust. All the layers together are the Crust, Mantle, Outer Core, and Inner Core.

What things have a core?
apples and Earth have a core
What are the differences of crust and mantle?
The Earth is made up thus: Inner core, outer core, mantle, crust. We live on the crust, with semi-plastic molten rock forming much of the mantle beneath us.
Is earth inner core Very dense?
No one is exactly sure how dense the core of the earth is. All we know is that the core is solid of an unknown density probably the density of a hard rock, and is denser than water for sure.ans2. Studies of the behaviour of seismic waves have given us some ideas about the inner core. It is probably a nickel-iron mixture, with other heavy metal contamination. The heat due to radioactive decay has raised the temperature to 5700 deg C, but it is solid because of the pressure. Some of the temperature is due to gravitational pressure.The inner core possibly rotates slightly faster then the lithosphere, though opinion is not agreed on this.
