This is a science worksheet designed to help students understand the geological processes of weathering, erosion, and deposition by matching images to their correct definitions.
The task is to categorize six images into one of three columns: Weathering, Erosion, or Deposition. The worksheet provides clear definitions at the bottom:
-
Weathering: Breaking Rocks
-
Erosion: Moving rocks and dirt
-
Deposition: Rocks and dirt stop moving
I will analyze each image one by one to determine which process it illustrates.

Image 1: Cracked Stone in Grass
-
First, look closely: This image shows a flat stone with visible cracks, sitting on green grass. The cracks suggest the rock has been physically broken apart.
-
Next, find information: Based on the definition "Breaking Rocks," this is a classic example of physical weathering, where forces like plant roots or temperature changes cause rocks to fracture.
-
Then, review the findings: This image belongs in the
Weathering column.

Image 2: Rocks Rolling Down a Hillside
-
First, look closely: This is a cartoon-style drawing showing several rocks tumbling down a steep slope, indicated by motion lines.
-
Next, find information: The definition for Erosion is "Moving rocks and dirt." This image directly depicts rocks being moved from one place to another by gravity.
-
Then, review the findings: This image belongs in the
Erosion column.
---
Image 3: Hammer Breaking a Rock
-
First, look closely: A hammer is shown striking a rock, causing it to shatter into smaller pieces.
-
Next, find information: While this is an artificial, human-caused action, it visually represents the concept of "Breaking Rocks," which is the definition of weathering. In geology, weathering can be physical (mechanical), and this is a direct illustration of that.
-
Then, review the findings: This image belongs in the
Weathering column.
---
Image 4: Pickaxe Striking a Rock
-
First, look closely: A pickaxe is hitting a large boulder, with small fragments flying off.
-
Next, find information: Similar to the hammer image, this is another depiction of breaking rock. Although done by a tool, it serves as an educational analogy for mechanical weathering.
-
Then, review the findings: This image belongs in the
Weathering column.

Image 5: Muddy River Flowing Through a Canyon
-
First, look closely: This photo shows a fast-flowing, muddy river cutting through a canyon. The water is visibly carrying sediment.
-
Next, find information: The definition for Erosion is "Moving rocks and dirt." Rivers are primary agents of erosion, transporting soil and rock particles downstream.
-
Then, review the findings: This image belongs in the
Erosion column.
---
Image 6: Hoodoos (Tall, Thin Spires of Rock)
-
First, look closely: These are tall, thin spires of rock, known as hoodoos, standing in a desert landscape. They are formed over long periods.
-
Next, find information: Hoodoos are formed by a combination of weathering (which breaks the rock) and erosion (which removes the material). However, their final shape is the result of deposition and the accumulation of more resistant rock layers on top. The key point is that these formations represent places where material has *stopped moving* and has been left behind after surrounding softer rock was eroded away. This fits the definition of "Rocks and dirt stop moving."
-
Then, review the findings: This image belongs in the
Deposition column.

Final Categorization
Based on the analysis, here is the correct placement for each image:
-
Weathering:
- Cracked Stone in Grass
- Hammer Breaking a Rock
- Pickaxe Striking a Rock
-
Erosion:
- Rocks Rolling Down a Hillside
- Muddy River Flowing Through a Canyon
-
Deposition:
- Hoodoos (Tall, Thin Spires of Rock)
This solution correctly matches each visual example to its corresponding geological process as defined by the worksheet.
