Since I can't view or access images directly, I can’t see the specific pictures you’ve uploaded. However, based on your description and the structure of the worksheet, it appears to be a science activity where students are asked to identify physical or chemical changes associated with various processes or images.
Let’s go through each row in the table and fill in the missing information based on common scientific understanding of the processes listed. If your images match these descriptions, this should help you complete the worksheet correctly.
---
- Name: Ice Melting
- Type (Physical/Chemical): Physical
- Description: Ice changing from solid to liquid water without altering its chemical composition (H₂O remains H₂O).
> 🔹 *Physical change because no new substance is formed.*
---
- Name: Wind Abrasion
- Type (Physical/Chemical): Physical
- Description: The process by which wind carries sand or other particles that wear away rock surfaces over time.
> 🔹 *Physical change—rock is broken down mechanically, but no chemical reaction occurs.*
---
- Name: Carbonation of Limestone
- Type (Physical/Chemical): Chemical
- Description: Rainwater absorbs carbon dioxide to form carbonic acid, which reacts with limestone (calcium carbonate) to produce calcium bicarbonate, dissolving the rock.
> 🔹 *Chemical change—new substances are formed (e.g., calcium bicarbonate).*
---
- Name: Glacial Abrasion
- Type (Physical/Chemical): Physical
- Description: Rocks embedded in glaciers scrape against bedrock, wearing it down through friction.
> 🔹 *Physical change—mechanical erosion without altering chemical identity.*
---
- Name: Food Weighing
- Type (Physical/Chemical): Physical
- Description: Measuring the mass of food using a scale. No change in the substance's composition occurs.
> 🔹 *Physical change—only measurement, not transformation.*
---
- Name: Exfoliation
- Type (Physical/Chemical): Physical
- Description: The peeling off of outer layers of rock due to pressure release (often after overlying rock is eroded), commonly seen in granite domes.
> 🔹 *Physical change—rock breaks apart due to stress, not chemical alteration.*

| Name | Type (Physical/Chemical) | Description |
|-------------------------|--------------------------|-------------|
| Ice Melting | Physical | Solid water turns into liquid water; no new substance formed. |
| Wind Abrasion | Physical | Wind carries particles that erode rock surfaces mechanically. |
| Carbonation of Limestone| Chemical | Carbonic acid reacts with limestone to dissolve it. |
| Glacial Abrasion | Physical | Glaciers grind rock surfaces, causing mechanical wear. |
| Food Weighing | Physical | Measuring mass without altering the food’s composition. |
| Exfoliation | Physical | Outer layers of rock peel off due to pressure release. |

✔ Summary:
- Physical Changes: Involve changes in state, shape, or size—no new substances.
- Chemical Changes: Involve reactions forming new substances.
If your images depict these processes accurately, then the above answers should match perfectly.
