No our earth has a crust>mantle>core> and an inner core.
Oh GOD, no!All planets have a full core and it's ussually liquid.The iron core it's what actually creates the magnetic field that supports Earth's atmosphere and deflects particles in the solar wind.A planet cannot be hollow because of gravity.The interior of the Earth, like that of the other terrestrial planets, is divided into layers by their chemical or physical (rheological) properties. The outer layer of the Earth is a chemically distinct silicate solid crust, which is underlain by a highly viscous solid mantle. The crust is separated from the mantle by the MohoroviÄŤiÄ‡ discontinuity, and the thickness of the crust varies: averaging 6 km under the oceans and 30â€“50 km on the continents. The crust and the cold, rigid, top of the upper mantle are collectively known as the lithosphere, and it is of the lithosphere that the tectonic plates are comprised. Beneath the lithosphere is the asthenosphere, a relatively low-viscosity layer on which the lithosphere rides. Important changes in crystal structure within the mantle occur at 410 and 660 kilometers below the surface, spanning a transition zone that separates the upper and lower mantle. Beneath the mantle, an extremely low viscosity liquid outer core lies above a solid inner core.The inner core may rotate at a slightly higher angular velocity than the remainder of the planet, advancing by 0.1â€“0.5Â° per year.
No, the Earth, and all other planets, are solid.Not only is this verifiable in numerous ways, including the mass, the temperature, and the magnetic field of the Earth, but a hollow planet is completely contradictory to gravity and couldn't naturally form under the laws of physics.
No it's not Hollow.Where does Lava come from?What's heating the interior off the planet?Our Earth has a molten core. You get taught this in like primary school. Here is a picture:http://www.google.co.uk/imgres?imgurl=http://i.bnet.com/blogs/earths-molten-core.jpg&imgrefurl=http://www.bnet.com/blog/sec-filings/more-bp-gulf-oil-spill-conspiracies-flourish-8212-from-algae-farms-to-armed-dolphins/472&h=363&w=335&sz=19&tbnid=mLYM0HyDk4N6ZM:&tbnh=2 34&tbnw=216&prev=/images%3Fq%3Dearths%2Bcore&zoom=1&q=earths+core&hl =en&usg=__3NiIqrLEFauCEY8-Cxc2WeelNmg=&sa=X&ei=28iPTM3nF5GUjAevxcCDDQ&ved=0C B4Q9QEwAQAnd here is some writing:Beneath the mantle is the Earth's core. The Earth's core consists of a fluid outer core and a solid inner core. Because the outer core contains iron, when it flows it generates a magnetic field. This is the source of the Earth's magnetic field. Structure of the EarthGeophysics, which studies the physics of the Earth, has led to many significant discoveries about the Earth and its make-up. Seismologic studies of the Earth have uncovered new information about the interior of the Earth that has helped to give credence to plate tectonic theory. Geophysical studies have revealed that the Earth has several distinct layers. Each of these layers has its own properties. The outermost layer of the Earth is the crust. This comprises the continents and ocean basins. The crust has a variable thickness, being 35-70 km thick in the continents and 5-10 km thick in the ocean basins. The crust is composed mainly of alumino-silicates. The next layer is the mantle, which is composed mainly of ferro-magnesium silicates. It is about 2900 km thick, and is separated into the upper and lower mantle. This is where most of the internal heat of the Earth is located. Large convective cells in the mantle circulate heat and may drive plate tectonic processes. The last layer is the core, which is separated into the liquid outer core and the solid inner core. The outer core is 2300 km thick and the inner core is 1200 km thick. The outer core is composed mainly of a nickel-iron alloy, while the inner core is almost entirely composed of iron. Earth's magnetic field is believed to be controlled by the liquid outer core.
No. All the planets are more or less solid and tend to become denser towards their cores (for at least a couple of different reasons). It would be next to impossible to have any large cavity in the interior of a planet, since no material is strong enough to hold up the immense pressure of the planet's surface, and so the planet would just collapse inwards anyway.
