The appropriate answer is a. the temperature is high enough but pressure low enough to melt iron. The earth's core is composed of two layers; the inner and outer core. Both layers are composed mainly of iron and nickel. The main difference between the two layers is that the inner core is solid and the outer core is liquid. The inner core is solid because of the pressure created by the overlaying layers; the outer core, mantle and the crust. The inner core is however hotter than the outer core.
From oldest to youngest: I, B, F, M, R, H.
Explanation:
On the picture we can see several layers of rock. Some of the layers have not been disturbed, so the principle of superposition can be applied to them. Some of the layer though have been disturbed by geological processes, so the layers are not at the same level because of it. On top of it, there is also an intrusion that has managed to further cause disturbance through all of the layers.
- The layer I is the oldest, and it is the basis of the others.
- Layer B has formed next, and after that layer F.
- These three layers have been influenced by the formation of fault, where one of their sides has been moving up relative to the other, while the other has been moving down relative to the other.
- Layer M is younger layer, and it can easily be seen as it totally covers the layer F below it.
- On top is layer R, which is the youngest of them all (the layers), and the one that comes out on the surface.
- Layer H is not really a layer, but it is an intrusion, which has formed after magma managed to cut through all the layers and later solidify. It is the youngest formation.

Where, I'm unsure, but when, I think I know. There is a theory that the first asteroid to hit Earth was actually a comet. It wiped out the dinosaurs.
