What state of matter within the outer core?
cool stuff
What is the movement of the inner core?
it is under so much pressure form the rest of the earth it behaves like a solid.
Which of the earth's layers is a liquid?
Generally speaking, the crust of the earth is a solid. Yes, there are oceans on the earth. Heck, they cover much of the surface. But the crust extends down well below the bottom of the ocean. Earth's crust is up to 70 kilometers deep, which is over 40 miles. The deepest the ocean gets is roughly 7 miles. A link is provided to the Wikipedia article on the earth's structure.
How was information about the inner core determined by scientists?
Seismic wave detection from the boundary between the inner and outer core indicated that the inner core may be solid. Studies of the Earth's magnetic field also indicates properties of the inner core that help form the magnetosphere which protects the planet from solar radiation. There is also evidence provided by the study of the composition of meteorites which were derived from planetary collisions. Much is still unknown, of course.
What is the outer core made of liquid or solid?
Melted iron and nickel alloy. It is too hot near the centre, so it is liquid. But if you want to know if the inner core is solid or liquid, then it is solid, because there is too much pressure from the rest of the Earth
Characteristics of outer planets?
The four outer planets; Jupiter, Saturn, Uranus and Neptune are all much larger than the inner planets. These outer planets have no real surface, they are composed mainly of Hydrogen and helium gas, which gets thicker and thicker until the extreme pressures closer to the core of the planets change the state of the gases. The outer planets are much colder than the inner planets due to their distance from the sun, they take much longer to orbit the sun due to this distance. The outer planets are a lot larger than the inner planets.
How can the inner core be hotter than the outer core but be in solid form while the outer core is in liquid form?
the outer core is not under enough pressure to be solid, but the inner core has so much weight being pressed against is from the mantle, crust, outer core, and gravity that it stays as solid nickel and can not move
How much kilometers is between the inner core and the outer core?
1700 kilometre between it other
What are two divisiosn of the earths core?
, a liquid outer core that is much less viscous than the mantle, and a solid inner core.
What state of matter within the outer core?
cool stuff
What are the layers of the earth about?
There is the Crust, Mantle, Outer core, and Inner core. There isn't really much to them. They are just the layers of the Earth
What is the only part of earths inner structure that is a liquid?
The inner and outer core are made mostly of molten rock and lead, as the very center is solid because of the constant force. The thick mantle is liquid towards the center and is primarily considered to be solid. The outer core is what I would say to be the "only" liquid layer in Earth's structure as the inner core has too much pressure and the mantle had too little heat.
How do inner planets differ?
Inner planets differ from outer planets because they have rocky core (excepting Pluto), and the are much smaller than outer planets, which are bigger and take more time to orbit Sun than inner planets because of their location. Outer planets are farther from the Sun than inner planets.
Which is thicker mantle or crust?
The crust is a thin outer layer. The mantle is much thicker.
Why are objects attracted to the inner core?
Gravity will attract the heavier elements to the core. The inner core is composed mainly of nickel and iron at about 5800oC; but the other heavy elements are there as well. It is solid because of the pressure. The outer core is still much the same composition, but because of less pressure, it is now liquid, but not too different in temperature.
Are the inner planets smaller than the outer planets?
yes the inner planets are much smaller then the outer planets
What is the movement of the inner core?
it is under so much pressure form the rest of the earth it behaves like a solid.
