7.1.3: Digging Deep

I turned in worksheet because you had to draw it.
2.) Density of the force increases as you go deeper below the crust.
3.) The extremely high pressure at the inner core drives the melting point of the iron and other materials up beyond the temperature of the inner core. Therefore that rock remains solid and doesn't melt.
4.)
A.) NO, its the other way around. Rock in the mantle is hotter, nearer to its melting point (through its still solid) and so can move around quite easily rock in the crust is more cooler, like frozen ice adn so its is much harder to move around.
B.) The difference of movement and no movement is that there is movement and no movement.
5.) letter D
6.)
A.) Seismic waves that go straight through Earth make the trip very quickly that tells us about the composition of Earth's center is that Alphine mpr-m850.
B.) s-waves: transverse and they can only travel through solids.
P-waves: longitudinal and they can only travel through solids and liquids.
7.) The Earth's core is thought to be predominantly iron (85%) with some (4-5%) nickel and the remaider.
