The core. The core consists of two parts, the outer core, which is liquid iron mixed with a few other things, and the inner core, which is a mass of solid iron about the size of the moon. The inner core is solid, rather liquid, because of the overwhelming pressure at the center of the earth, which would make it very dense. The mantle is made of rock that is dense but still fairly flexible and the crust is made mainly of materials that are less dense than rest of the earth's interiors.
Also, think of it this way: you have an empty glass which you will pour three different liquids into. The liquids are add are water, corn syrup, and vegetable oil. It doesn't matter which order you pour them into, but in the end, the oil will stay mainly on top, the water in the middle, and the corn syrup at the bottom. This is because the oil is the least dense of the three liquids and the corn syrup is most dense, leaving the water in the middle. The same sort of principle applies to the earth's interior: the denser the material, the farther down it will go. Thus the core is the densest.
The reason for the most dense material going to the bottom relates to gravity. Say you have two objects. They are the exact same size (same volume and everything) but one is denser than the other (meaning it has a greater mass.) The greater the mass of an object, the greater the effect that gravity has on it (the reason why of the two objects, the denser one would feel heavier.) So naturally, the heavier object will tend to fall furthest to the bottom if given the chance. Hope this helped

core... the crust is the thinnest by the way.... and mantle the second thickest....

The core.
Unless you find the Earth was hollow, you could pull it inside out.
