What did you use to represent a river?

Answer explanation

✅ Correct Answer: Water

🌊 Explanation:
Water best represents a river because rivers are made of moving water that can wear away land over time.

What landform was created due

to weathering and erosion?

• Valley
• Hill
• Canyon
• Plateau

Answer explanation

✅ Correct Answer: a) Canyon

⛰️ Explanation:
A canyon forms when moving water slowly cuts deep into land over a long period of time.

Canyon's are also called V-Shaped Valleys due to the shape looking close to a V.

What agent of change was

responsible for the landform?

• Water
• Volcanoes
• Ice
• Wind

Answer explanation

✅ Correct Answer: a) Water

💧 Explanation:
The agent of change is what causes the land to change. In this lab, moving water caused erosion. Erosion means to move!

What are the limitations of your model? Select ALL that apply!

• Size

• Materials

• Agent of Change

• Amount of Time

Answer explanation

✅ Correct Answers:

• a) Size

• c) Amount of Time

• d) Materials

⏳ Explanation:

• The model is much smaller than a real canyon

• The model forms in minutes, not millions of years

• The materials are not real rock

⚠️ These are common model limitations.

However, you should have used water as the agent of change just like how real life canyons/v-shaped valleys are formed.

What are the advantages of your model? Hint: Did your model create the correct landform? Use some of the same materials? Use the same agent of change as the real process would?

Answer explanation

✅ Strong Answer Should Include:

• It used the correct agent of change (water)

• It created the correct landform (canyon)

• It showed erosion happening

🌟 Big Idea:
Even if models aren’t perfect, they help us see processes that take a long time.

What factors and processes lead to the formation of a canyon?
A canyon forms through ______​ and ______ ​ by the moving water of a river over time.​

Word Bank: Weathering, Erosion, Deposition

Answer explanation

✅ Correct Answer:
A canyon forms through weathering and erosion by the moving water of a river over time.

🧠 Explanation:

• Weathering breaks down rock

• Erosion moves the broken pieces away

• Together, they slowly create deep landforms

Did a delta form at the mouth

(end) of the river? Why or why

not?

Answer explanation

9. Did a delta form at the end of the river? Why or why not?

✅ Expected Explanation:
A delta forms when sediment is deposited at the end of a river.
If water slowed down and dropped sediment, a delta could form.
If not, there was not enough sediment or time.

🌍 Key word: Deposition

What is the reason why this canyon was formed?

• wind movement

• water movement

• ice movement

• hot springs

Answer explanation

10. Why was this canyon formed?

✅ Correct Answer: b) water movement

💦 Explanation:
Canyons are carved by moving water, not heat, wind, or ice in this lab.
