Alice's fall and her sizes: falling, the centre of the Earth, giants and tiny people, sentence 10

The Earth's centre is a ball of iron and nickel about as hot as the surface of the Sun, and around it is a layer of melted metal, so no tunnel could ever be dug through.

Who acts: centre · What happens: be, melt, dig through · To what, where: ball, layer, tunnel
