Let’s solve each part step by step.

---

Part 1: Label the diagram

We are given these terms to use:
→ crust, inner core, lithosphere, mantle, outer core

Looking at the Earth diagram:

- a) points to the very center → that’s the inner core
- b) points to the layer just outside the inner core → that’s the outer core
- c) is already labeled as lithosphere (which includes the crust and top of the mantle)
- d) points to the thick middle layer → that’s the mantle
- e) points to the thin outermost layer → that’s the crust

So:
a) inner core
b) outer core
c) lithosphere (already filled)
d) mantle
e) crust

Part 2: Write the terms for the definitions

a) the central layer of the geosphere → inner core
b) the thickest layer of the geosphere → mantle (it’s much thicker than crust or cores)
c) the solid outer part including crust and top of mantle → lithosphere
d) the top layer of the geosphere → crust
e) the layer around the central layer → outer core (surrounds the inner core)

---

Part 3: Correct one mistake in each sentence

a) “The core is the centre of the geosphere.”
→ Mistake: It should be inner core, not just “core” (since there are two cores).
✔ Correction: The inner core is the centre of the geosphere.

b) “The lithosphere is made up of the crust and the part of the mantle.”
→ Mistake: It’s the top part of the mantle, not just “part”.
✔ Correction: The lithosphere is made up of the crust and the top part of the mantle.

c) “The part of the Earth is called the geosphere.”
→ Mistake: Should say “The solid part...” because geosphere = solid Earth.
✔ Correction: The solid part of the Earth is called the geosphere.

d) “The is made up of magma.”
→ Mistake: Missing word — it should be “The mantle” (magma comes from melted rock in the mantle).
✔ Correction: The mantle is made up of magma. *(Note: Actually, mantle is mostly solid but can flow; magma forms when parts melt. But for this level, we’ll go with common simplification.)*
Wait — actually, better correction: Magma is found in the mantle, but the mantle isn’t *made* of magma. Maybe the intended error is missing subject? Let’s re-read: “The ___ is made up of magma.” Most likely they mean asthenosphere or just accept “mantle” as simplified. But since “mantle” is in our word bank, and often taught this way, we’ll go with:
✔ Correction: The mantle is made up of magma. *(Accepting curriculum-level simplification)*

Actually — let’s check standard teaching: Often, students are told the mantle contains magma or is semi-molten. So yes, “mantle” fits here.

e) “Magma is semi- rock.”
→ Mistake: Should be “semi-molten rock” or “semi-solid”? Wait — magma is molten rock. Lava is magma on surface. But “semi-rock” doesn’t make sense. Probably meant “semi-molten” — but actually, magma is fully molten. Hmm.

Wait — perhaps the mistake is “semi-” — maybe it should be “molten rock”, without “semi-”. Because magma is liquid/molten, not semi.

But sometimes it’s described as “semi-fluid”. However, looking at common corrections:

Actually, in many textbooks, magma is defined as “molten rock”, so “semi-” is wrong.

✔ Correction: Magma is molten rock. (Remove “semi-”)

But the instruction says “correct one mistake”, so if we remove “semi-”, then it becomes “Magma is rock.” which is incomplete.

Better: Change “semi-” to “molten” → “Magma is molten rock.”

Yes.

Alternatively, if they expect “semi-solid”, that’s incorrect for magma — magma is liquid.

I think best correction: Replace “semi-” with “molten”

So: Magma is molten rock.
