1. what happens to the riverbed as water is poured on it?

2. is the water breading down the riverbank an example of (circle one) weathering, erosion, or deposition?
3. as the water flows down the pan, it carries little pieces of sand. is this an example of (circle one) weathering, erosion, or deposition?
4. the sand particles gathered at the bottom of the sheet tray are examples of (circle one) weathering, erosion, or deposition.
independent practice:
read each of the following scenarios. circle key words in the scenario. decide whether the scenario is describing weathering erosion or deposition.
| scenario: | w, e, d.. why? |
| ---- | ---- |
| flood water pounding against a canyon wall and wearing it down | |
| rain washing away soil from a hillside | |
| layers of sediment forming at the bottom of the ocean | |
| a mudslide flowing down a steep hill | |
| glaciers dropping rock and sand to form terminal moraines | |
| waves dropping sand on the beach | |
| caves being formed by acid rain dissolving underground limestone | |

Accepted Answer

# Brief Explanations:
1.  When water flows over a riverbed, it picks up and moves small sediment particles, gradually wearing away the riverbed and shaping it over time.
2.  Weathering is the breakdown of rock/soil in place; erosion is moving broken material; deposition is dropping material. Breaking down a riverbank in place is weathering.
3.  Carrying sand particles via flowing water is the movement of sediment, which is erosion.
4.  Sand gathering at the bottom of a tray is sediment being dropped and left behind, which is deposition.
For the independent practice:
- Weathering (W) = breaking down material in place; Erosion (E) = moving broken material; Deposition (D) = dropping/leaving sediment in a new location.
# Answer:
1.  The water will erode the riverbed, picking up and moving small sediment particles, gradually shaping and deepening it over time.
2.  weathering
3.  erosion
4.  deposition

### Independent Practice:
| Scenario | W, E, D.. Why? |
|----------|----------------|
| Flood water pounding against a canyon wall and wearing it down | W; Breaks down rock in place |
| Rain washing away soil from a hillside | E; Moves soil to a new location |
| Layers of sediment forming at the bottom of the ocean | D; Sediment settles and accumulates |
| A mudslide flowing down a steep hill | E; Moves broken soil/rock downhill |
| Glaciers dropping rock and sand to form terminal moraines | D; Glaciers deposit sediment they carried |
| Waves dropping sand on the beach | D; Waves deposit sand they transported |
| Caves being formed by acid rain dissolving underground limestone | W; Dissolves rock in place |
