light and heat(i heard some1 say radiation 1ce but i dont think its true)

∙ 12y agoThe Earth's internal heat comes from a combination of residual heat from planetary accretion (about 20%) and heat produced through radioactive decay (80%).

Is the earths core solidifying and the magnetic field waning so that the atmosphere is stripped away by the solar wind leading to colder winters and hotter summers?
yes
Why do humans live on the outside layer of the earth?
If we did not live on the outer layer of the Earth also known as the crust we would burn to death because it is so hot down below because the core of the Earth is so hot
Convection in the What creates earths magnetic filed?
Earth's molten outer core rotates. That outer core is made up mostly of molten iron. The movement of the molten iron produces the magnetic field.When currents in the outer core force the solid inner core to spin at a slightly faster rate than the rest of the planet causes the Earth to have a magnetic field.
Why is there so much more pressure exerted on the earths core than on the earths surface?
Pressure is the weight of an overlying column of material. The pressure at the core comes from 6400km of overlying rock, which is much denser than air
Can a helicopter or plane get out of the gravitational pull on earth?
That deppends... if you mean the atmosphere which would equal zero gravity than yes but the earths gravitational pull is what keeps the moon where it is so the planes or helicopters wouldn't be able to get completely out of the pull
Is earths core a solid?
no the core of the earth is not solid its pretty much a liquid, since the middle of the earth is so hot, the core is like a lava substance.
What if us as people from earth decided to mine iron and nickel from the earths core?
1. we would never be able to get down to the bottom to the core because we dont have the machineary and if we got past the earths crust hot molten lava would pour out and destroy the country. 2. if we mined the earths core it would be so hot no thing could survive it and we couldn't mine it because it is extremely hard
Why the world will end of 2012?
because most scientist believe that earths core will get so hot that every volcano will explode and cover the whole world with lauve.
What does earth look like inside?
The inside of the Earth has four different layers. The core is the earths heat source, a ball of lava. then there is the outer core, a bit cooler. finally comes another layer of mantle and then the crust (which is the land we walk on).
How is the structure of earth and the structure of a peach similar?
Sorry. The earths core reminds me of an apple. So here goes. In the center of the apple, there is a core, and that is the hardest a biggest part. So that is the earths core. The crust is the skin of the apple, and that is also the thinnest. The rest is the outer core and mantle.
Is earths outer core liquid or solid?
So far as science can deduce, it must be a solid.
What is the earths outter core composed of?
iron and nickel is the answer and so is the inner core. the inner and the outer and together but the outer core is liquid and the inner core is solid
What causes earths dense core?
Because the gravity is pushing the core together more so its more dense.
What metals makes up the core?
The outer core is a layer of the Earth, the second to last layer. It creates the Earths Magnetic field by moving around the inner core. There are two metals that make up the outer core, these two metals are iron and nickel. The inner core is so hot that it melts the nickel and iron turning it into liquid magma.
What is a body wave that can penetrate the earths core?
It's called the P- Wave
Why is the core in the center of the earth hot?
Because, there is so much pressure the core get's extremly hot, and there is lava, and sometimes its yellow.
Does earth's molten core affect gravity?
First: The earths core is not molten, it is a very dense solid mass, kept solid by the intense pressure on it. Second: It is the layer around this core that is molten, and yes it does influence gravity, but more so earths magnetism.
