Question

1. which 2 layers make up lithosphere?
2. where is the crust thicker, oceans or continents?
3. where is the crust denser, oceans or continents?
4. what is the outer core believed to be made up of?
5. what is the inner core believed to be made up of?
6. what 2 layers of the earth are either partially or totally melted?
7. between which 2 layers do you find the moho?
8. what rock is continental crust made up of?
9. what rock is oceanic crust made up of?
10. why are there???s on this chart? what does this mean?
11. what happens to the temperature as you travel deeper into the earth?
12. what happens to pressure as you travel deeper into the earth?
13. why do we call the asthenosphere \the plastic mantle\?
14. what are the 3 layers of the mantle?
15. plates move together or apart at mid ocean ridges?
16. plates move together or apart at trenches?
17. mountains are found at mid ocean ridges or trenches?

Explanation:

1. The lithosphere combines the rigid outer layers.
2. Confirmed correct: continental crust is thicker.
3. Oceanic crust is denser due to composition.
4. Confirmed correct: outer core is iron-nickel.
5. Confirmed correct: inner core is iron-nickel.
6. These layers have molten/partially molten material.
7. The Moho is the boundary between crust and mantle.
8. Confirmed correct: continental crust is granite.
9. Confirmed correct: oceanic crust is basalt.
10. The "???" indicate missing data to research/fill.
11. Confirmed correct: temperature increases with depth.
12. Pressure increases due to overlying rock weight.
13. The asthenosphere has a plastic, deformable texture.
14. Corrected: mantle layers are top asthenosphere, middle/lower stiff mantle.
15. Mid-ocean ridges are divergent plate boundaries.
16. Trenches are convergent plate boundaries.
17. Trenches are linked to mountain formation via subduction.

Answer:

1. Crust and Stiffer Mantle
2. CONTINENTS
3. Oceans
4. IRON AND NICKEL
5. IRON AND NICKEL
6. Asthenosphere and Outer Core
7. Crust and Stiffer Mantle (Mantle)
8. GRANITE
9. BASALT
10. They mean the data is missing and needs to be researched or filled in.
11. IT INCREASES
12. It increases (becomes greater)
13. It has a plastic, partially molten texture that can slowly deform.
14. Asthenosphere, Stiffer Mantle (Upper Mantle, Lower Mantle)
15. Apart
16. Together
17. Trenches
