Weathering Erosion Deposition Revision

Name:

Date:

Rock formations showing weathering and erosion

🎯 Learning Intentions & Success Criteria

We are learning to: Understand how weathering, erosion and deposition shape our Earth's surface

Success Criteria - I can:

✓ Define weathering, erosion and deposition

✓ Give examples of each process in Australia

✓ Explain how these processes work together to change landscapes

✓ Identify which process is happening in different scenarios

📚 Part 1: Key Definitions & Multiple Choice

1. Weathering is the breaking down of rocks into smaller pieces. Which is the BEST example of weathering in Australia?

Water carrying sand down the Murray River

Tree roots cracking rocks in the Blue Mountains

Sand building up on Bondi Beach

Wind moving dust across the Nullarbor Plain

2. Erosion is the movement of weathered rock pieces. Which of these shows erosion? (Choose ALL that apply)

Waves washing sand away from a beach

Wind carrying red dirt in the outback

A glacier moving rocks down a mountain

Salt crystals forming in rock cracks

3. Deposition occurs when eroded materials are dropped in a new location. The best example is:

Uluru being carved by wind over millions of years

Soil and rocks building up in river deltas

Limestone caves forming underground

Granite breaking apart due to temperature changes

4. Complete the sequence: Weathering → _____________ → Deposition

Formation

Erosion

Sedimentation

Transportation

✏️ Part 2: Understanding & Application

5. Explain how the three processes (weathering, erosion, deposition) work together to create a river delta. You may look up an example of the river delta. Use the words: break down, carry, drop

6. A student observes pebbles at the bottom of a cliff after a storm. Which process moved the pebbles there?

Process: _________________

Explain your reasoning: ________________________________________________

7. DEEPEN: Compare how weathering happens differently in tropical North Queensland versus the cold Snowy Mountains. Give one example for each location.

8. EXTENSION - Higher Order Thinking: Predict what would happen to Australia's coastline if there was no deposition for 100 years. Justify your prediction using scientific reasoning.
