Question

1. use information from the link above to complete the chart and questions. scroll down to the subheadings “outer core” and then “inner core” and then “magnetism”

	thickness (km)	made of what metals?	temperature range (°c)	liquid or solid state?
inner core			6,200 celsius

1. why is the inner core in a solid state rather than a liquid state given the extremely high temperatures?

1. which layer creates the earth’s magnetic field?

review questions

1. what is the deepest, hottest layer?
2. which layer has both a soft semi - solid part and a solid part?
3. which layer is completely in a liquid state?
4. list the 3 layers that are in a completely solid (rigid) state:

1. in general, as depth increases, how does temperature and pressure change inside the earth?

1. if you could travel the following distances, in what layer of the earth would you find yourself?

Explanation:

1. Without the link - for reference, we can't fully complete the chart. But generally, the outer core thickness is about 2,200 km, it is made of iron and nickel, temperature range is 4,000 - 5,500°C and it is liquid. The inner core thickness is about 1,220 km, made of iron and nickel, temperature is about 5,200°C and it is solid.
2. The inner core is solid due to the extremely high pressure at the Earth's center which overcomes the effect of high temperature that would otherwise cause it to melt.
3. The outer core creates the Earth's magnetic field through the movement of the liquid iron - nickel alloy (dynamo effect).
4. The inner core is the deepest and hottest layer.
5. The mantle has both a soft semi - solid (asthenosphere) part and a solid (lithosphere) part.
6. The outer core is completely in a liquid state.
7. The crust, the lithospheric part of the mantle, and the inner core are in a completely solid (rigid) state.
8. As depth increases inside the Earth, both temperature and pressure increase.
9. Without specific distances given, we can't answer. But for example, if within 0 - 50 km, it's the crust; if deeper than 2,900 km, it could be the inner or outer core depending on the exact depth.

Answer:

1. Outer Core: Thickness - 2,200 km, Metals - Iron and Nickel, Temperature Range - 4,000 - 5,500°C, State - Liquid; Inner Core: Thickness - 1,220 km, Metals - Iron and Nickel, Temperature - 5,200°C, State - Solid
2. High pressure at the Earth's center makes it solid despite high temperature.
3. Outer Core
4. Inner Core
5. Mantle
6. Outer Core
7. Crust, Lithospheric part of mantle, Inner Core
8. Both temperature and pressure increase.
9. No specific distances provided, can't answer.
