What are two reasons families might choose to settle in certain landforms?
They may seek fertile soil for agriculture or access to resources like the ocean for fishing.
In what ways have the people of Rio de Janeiro adapted to their mountainous landscape?
In what ways have the people of Rio de Janeiro adapted to their mountainous landscape?
They have developed a cable car system to navigate the terrain and built homes that accommodate the mountainous environment.
How does alluvial deposition contribute to landform development?
How does alluvial deposition contribute to landform development?
Alluvial deposition occurs when rivers carry sediment and deposit it along their banks, shaping new landforms like deltas.

Study Notes
Landforms and Their Influence
- Landforms significantly impact where people live and what they do.
- People often settle near fertile land, like river valleys or deltas, for agriculture or other purposes.
- Harsh climates or rugged terrain, like the Sahara Desert or Himalayas, discourage settlements.
- Landforms affect jobs and culture.
- For example, mining may thrive in areas with rich mineral deposits.
- Varying landscapes also influence languages, as seen on New Guinea.
Types of Landform Creation
- Glaciers create large U-shaped valleys by carving and crushing rock sediment.
- Water is a major erosive force, carving canyons and coastlines.
- Rivers create floodplains via alluvial deposition.
- Rivers also create deltas by depositing sediment and forming land at the point where they meet the sea.
- Sediment deposition from flowing water leads to new landforms.
Living with Landforms
- People in Rio de Janeiro have adapted to their mountain and bay environment.
- Rich mineral deposits in locations such as the Colorado mountains lead to specific industries like mining.
