The earth's core contains radioactive elements and as these decay they release heat. This heat keeps the earth's core hot.
It's uncertain why anyone would tell you this, but it's certainly not true; the Earth's gravity is not dependent upon having a molten core.
Yes, the closer you are to the center off the gravitational point the stronger it is. unless you are actually in the center, then you are weightless, because your mass is equal in all directions.
Yes, but we would die first because gravity holds down air (oxygen and nitrogen and other stuff) and if the gravity leaves, then there's no air to breathe. No need to worry. Gravity isn't going anywhere any time soon.
No.-----The earth has an important magnetic field.No, Earth would lose its magnetic field if its molten iron core were not moving. Scientists speculate that Mars had a magnetic field a long time ago but lost it when the planet cooled to the point that its core solidified.
The iron core of the earth is solid because the immense pressure near the center of the earth, due to gravity, keeps the iron in a solid state, even though it is hot.
the term crust is suitable for the layer of the earth we live on because it is the rocks that cooled from the outer core under it.
If there is no Sun Light the Core of the earth would cool, all living organisms would be killed and when the sore of the earth cooled the earth would implode due to a sub-normal reaction between heat and gravity, the gravity would win and implode the earths crust. This would cause a huge super-nova in our galaxy and send earth particles flying through the universe.
in the core
Partially. Every bit of mass on and within Earth contributes to its gravity.
The Earth's Core lies at the centre.
it is found in the core.
Yes, but not for quite the reason you might think. If Earth were the same density throughout, gravity would decrease as you moved toward the center, as more and more of Earth's mass would be above you. However, Earth's density is not uniform. Earth's core is made mostly of iron, which is much denser than the rock that makes up the crust and mantle. So gravity would increase as you got closer to the dense. Once you cross into the core, gravity starts to decrease as described above until you reach the very center, where gravity (at least from Earth) is zero.
gravity pulls us towards the centre (core) of the earth. because bears.
The magnetic core of the earth pulls on the mass of the pencil.
Because gravity is stronger with a bigger object. The greatest effect on the gravity you undergo has to do with the immense electromagnetivity from the Earth's core. There are none of those physical factors in space.

No, gravity is a force of attraction acting between all objects that have mass.
