MOVEMENT IN MANTLE CAUSES VOLCANIC ERUPTIONS AND EARTHQUAKES. THE CORE,BENEATH THE MANTLE,IS THE DEEPEST AND HOTTEST LAYER OF THE EARTH.IT IS ALMOST ENTIRELY MADE OF METAL.IT HAS TWO LAYER: THE INNER CORE AND THE OUTER CORE. THE OUTER CORE BORDERS THE MANTLE. THE INNER CORE IS SHAPED LIKE A BALL.
Q. What are 4 characteristics of the core?

Q. What are 5 facts about the core?
5 Facts About the Earth’s Inner Core
- It’s Almost The Size of the Moon. The Earth’s inner core is surprisingly large, measuring 2,440 km (1,516 miles) across.
- It’s Hot…Really Hot.
- It’s Mostly Made of Iron.
- It Spins Faster Than the Surface of the Earth.
- It Creates a Magnetic Field.
Q. What is the function of the earth’s core?
The Earth’s core comprises a solid inner core and liquid outer core, both made mostly of iron. Outside of these parts are the mantle, then the crust on which we live. Earth scientists have theorized that the Earth’s core is responsible for the planet’s magnetic field as well as plate tectonics.
Q. What is the main component of Earth’s core?
Unlike the mineral-rich crust and mantle, the core is made almost entirely of metal—specifically, iron and nickel. The shorthand used for the core’s iron-nickel alloys is simply the elements’ chemical symbols—NiFe. Elements that dissolve in iron, called siderophiles, are also found in the core.
Q. Can we reach the Earth’s core?
But we’ve never been to the planet’s core. The central point of the Earth is over 6,000km down, and even the outermost part of the core is nearly 3,000 km below our feet. The deepest hole we’ve ever created on the surface is the Kola Superdeep Borehole in Russia, and it only goes down a pitiful 12.3 km.
Q. How close to the Earth’s core have we been?
Verne’s characters only made it a few miles down but the idea that anyone could even contemplate travelling to the Earth’s core had been dismissed before Victorian times. In fact even today, the furthest we’ve drilled into the Earth is around 12km, while the distance to the centre is over 500 times further, at 6,370km.
Q. Where is Earth’s crust thickest?
The crust is thickest under high mountains and thinnest beneath the ocean. The continental crust consists of rocks such as granite, sandstone, and marble.
Q. Can a meteor hit the sun?
No asteroids have ever been observed to hit the Sun, but that doesn’t mean that they don’t! Orbits within in a Kirkwood gap are not stable, and any asteroid whose orbit wanders into such a region will eventually get pulled into a different orbit, which may take it into the inner solar system.
