1. TOPOGRAPHIC MAPS Part 2
A NEW WAY TO VIEW THE WORLD!

2. Topographic map examples
Sometimes topographic maps show islands

3. Sometimes topographic maps show canyons

4. Sometimes they show mountains.

5. Sometimes they are simple
Sometimes they are complicated

6. Sometimes they show many landforms over a large region.
Sometimes they show a single landform in detail.

7. Weathering: Erosion: Weathering and Erosion
The physical or chemical break down of rock due to water, wind, or ice
Erosion:
The relocation of sediment by wind, water or ice

8. Mountain Weathering and Erosion
If weathering and erosion occur, contour lines on a topographic map may change.
For a mountain, contour lines may become more spread out. This happens as the elevation becomes less steep as rock material is broken down (weathering) and carried away (erosion).

9. Canyon Weathering and Erosion
For a canyon, contour lines may become closer together. This happens as the elevation becomes more steep as rock material is broken down (weathering) and carried away (erosion).

10. Deposition: Deposition
Solid fragments of rock that come from the weathering of rock, are eroded, and then deposited by wind, water, ice, or gravity.

11. Deposition & Deltas
As sediments are carried by rivers, they may build up and create deltas at the mouth of a river.
Topographic maps of the area may show evidence of delta formation as contour lines form a “V” shape.
