Question

1. the lithosphere contains part of the crust and the upper mantle. what does lithosphere mean? 4. what part of the earth can be found in the lithosphere? 5. how can the lithosphere move? now, click on the asthenosphere 6. how does the rock move in the asthenosphere? now, click on the mantle. 7. what layers make up the mantle? 8. how thick is the mantle? now, click on the outer core. 9. the outer core is \molten\. what do you think that means? 10. the core is responsible for what? lastly, click on inner core. 11. is the inner core a liquid or solid? why? 12. how hot is the inner core? now, exit out of this section and go to: label the earth diagram (http://www.enchantedlearning.com/subjects/astronomy/activities/label/labelearth.shtml) label and color the earth diagram

Explanation:

1. The term "lithosphere" comes from Greek, where "lithos" means stone. It refers to the rigid, outermost shell of the Earth.
2. The lithosphere contains the crust and the uppermost part of the mantle.
3. The lithosphere moves due to convection currents in the asthenosphere below. These currents cause the tectonic plates (which make up the lithosphere) to move slowly over time.
4. In the asthenosphere, rock moves in a semi - plastic manner due to high temperature and pressure, allowing for slow deformation and flow.
5. The mantle is made up of the upper mantle and the lower mantle.
6. The mantle is about 2,900 kilometers (1,800 miles) thick.
7. "Molten" means that the outer core is in a liquid state, composed mainly of iron and nickel that are melted due to high temperatures.
8. The core is responsible for generating the Earth's magnetic field, among other things.
9. The inner core is solid. The extreme pressure at the center of the Earth keeps the iron - nickel material in a solid state despite high temperatures.
10. The inner core is extremely hot, with temperatures reaching about 5,500 °C (9,932 °F).
