The earth's core contains radioactive elements and as these decay they release heat. This heat keeps the earth's core hot.

True or false gravity comes from the center of the earth?

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.


Is Venus a permanent magnet?

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.


Why is there so much more of these metals at the core than the Earth's crust?

The Earth's core contains significantly more of certain metals, such as iron and nickel, due to the process of differentiation during the planet's formation. As the Earth cooled, heavier elements sank to the center under the influence of gravity, forming the dense core, while lighter materials rose to form the crust. Additionally, the high pressure and temperature at the core facilitated the accumulation of these metals, which are less stable in the crust under surface conditions.


Why is iron core of the earth solid?

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.


What would happen if the force of gravity were to disappear suddenly?

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.

What will happen to people and animals if their is no sunlight?

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.


What would happen if the Earth's core cooled?

If the Earth's core cooled, it would lead to a decrease in the planet's magnetic field, which protects us from harmful solar radiation. This could result in more exposure to radiation, affecting our atmosphere and potentially causing disruptions to technology and communication systems.


Where is the earth center of gravity?

The center of gravity of Earth is at its core, which is near its geometric center. It is the point where the gravitational pull on an object can be considered to act.


Does the earth get its gravity from the inner core?

Partially. Every bit of mass on and within Earth contributes to its gravity.


Is there gravity at the center of the Earth?

Yes, there is gravity at the center of the Earth. The force of gravity is present throughout the entire planet, including at its core.


What lies at the centre of gravity and earth?

The Earth's Core lies at the centre.


Where is the force of gravity located on the Earth?

it is found in the core.


Can you dig through the Earth's core and escape the central gravity there if you found a way to withstand the heat?

No, it is not possible to dig through the Earth's core as it is made up of extremely hot and molten materials that would make any attempt to withstand its heat impossible. Additionally, the gravity at the Earth's core is likely to be much stronger and escaping it would not be feasible.


Does gravity push us toward the earth?

gravity pulls us towards the centre (core) of the earth. because bears.

Why do you feel the affects of gravity more when you are here on Earth than you would out in space?

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.


Is gravity a core in the center of the earth?

Gravity is not a physical object that can be located at the core of the Earth; rather, it is a fundamental force of nature that is caused by the mass of objects. The core of the Earth is predominantly composed of iron and nickel, and it is the immense mass of the Earth itself that generates the gravitational force we experience.
