Overview of Weathering and Erosion concept map showing agents of erosion and types of mass movement.

Let’s go step by step to fill in the blanks using the word list:
gravity, water, rock slides, mudflows, creep, mechanical, ice

---

Step 1: Look at “Weathering” section

Weathering is caused by two main types:

- One side says: “ice wedging and living organisms is ___” → This describes mechanical weathering (breaking rocks without changing their chemistry). So blank 1 = mechanical

- The other side says: “natural acids and oxygen is chemical” → That’s already filled. Good.

Step 2: “Agents of erosion” include four things

We know one is wind. What are the other major agents?

From the word list: water, ice, gravity

So blanks 2, 3, 4 should be: water, ice, gravity — order doesn’t matter as long as they’re all there.

But let’s match them logically:

Usually we say: water, wind, ice, gravity → so:

Blank 2: water
Blank 3: ice
Blank 4: gravity

(You could swap 3 and 4, but this is standard.)

Step 3: “Types of mass movement include”

Mass movement means stuff moving downhill due to gravity.

Given clues:

- “soil particles moving downhill, or ___” → that’s creep (slow movement) → blank 5 = creep

- “wet sediment moving downhill, or ___” → that’s mudflows → blank 6 = mudflows

- “sediment moving along curved surfaces, or slump” → already given

- “rock layers breaking loose, or ___” → that’s rock slides → blank 7 = rock slides

Now let’s double-check all words from the list are used:

Word list: gravity, water, rock slides, mudflows, creep, mechanical, ice

Used:

1. mechanical ✔
2. water ✔
3. ice ✔
4. gravity ✔
5. creep ✔
6. mudflows ✔
7. rock slides ✔

Perfect — all words used once.

Final Answer:
1. mechanical
2. water
3. ice
4. gravity
5. creep
6. mudflows
7. rock slides
