Weathering
Erosion
Deposition
Glaciers

NY Landscapes

2. How does Groundwater work?
                                                                              
Water falls to the ground and infilitrates the soil. It finally stops when it hits the bedrock.

3. Characteristics of the soil
Permeability: How quickly water passes through a surface (Larger the better)
Porosity: open space in the soil (size doesn’t matter)
Capillarity: upward movement of water in the ground (Smaller the better)
Runoff: water found on the surface

4. What is the soil horizon?
Soil Horizon is a profile of the ground and how the bedrock is transformed into fertile soil.
A: Topsoil: Fertile: Humus/ organic materials
B: Middle: Mineral Enriched
C: Bottom Solid Bedrock

5. What is weathering? Breakdown of a substance. Physical-smaller pieces
Climate: Cold & Moist
Chemical- change
Climate: Warm & Moist

6. What is Erosion? Erosion: Movement of materials Chief Agent: Water
Rivers move sediments Table pg6
Move fastest in straight middle
Curve fastest outside bend

7. ESRT pg 6

8. What is deposition? Deposition:Settling of Sediments Factors:
Size, Shape, Density
Horizontal: Largest sediments closest to the mouth
Vertical: Largest sediments on the bottom

9. How are landscaped shaped?
By the deposition and erosional processes.

10. How do places that were affected by Glaciers Look?
Glaciers: Unsorted sediments in ground
Rocks have striations (Scratches)
Valleys are “U” Shaped

11. How do places that were affected by water look?
Water: Sediments sorted. Either vertical or horizontally
Sediments are smoother, rounder and smaller
Valleys are “V” Shaped
