Major Concepts in The W.E.D. Unit:
How is Earth's Lithosphere effected by interactions with the atmosphere and
hydrosphere?
- What is weathering?
- When does weathering occur?
- How do climate factors (moisture and temperature) effect the type and rate
of weathering?
- How does particle size effect the rate of weathering of a material?
- How does the mineral composition of a rock effect its rate of weathering?
What are the products of the weathering process?
- What is the composition of soil?
- How do soil horizons develop?
- How does human activity effect the distribution and quality of soil?
How are products of weathering transported?
- What is the difference between erosion and deposition?
- In New York State, how does the amount of residual material compare to the
amount of transported material?
- What is the primary FORCE that drives all agents of erosion?
- What is considered to be the dominant AGENT of erosion acting on Earth at
this time?
- How does the velocity and discharge of a stream effect its carrying
capacity?
- How does the shape of a stream channel effect where erosion and deposition
will occur?
- What are the four methods of stream sediment transport?
What factors control the deposition of eroded materials?
- What are the factors that control the rate and pattern of sediment
deposition?
- Explain how water and wind deposit sediment in layers.
- What are some of the natural features that are created by horizontal
and vertical sorting of sediment?
- Compare and contrast glacially deposited sediments from stream and/or
wind deposited sediments.
How is Earth's surface shaped by weathering, erosion, and deposition?
- What are the factors that influence the rate of landscape development and
landscape patterns?
- Which agent of erosion has most greatly altered the landscape of New York
State?
- How does human activity influence landscape development?
- What are the types of stream drainage patterns and the landscapes
associated with them?
