Study Notes
Valleys
- Valleys are low-lying landforms between hills or mountains.
- Valleys form due to erosion, the natural process of water wearing down rocks and soil.
- Water flowing down mountains carves V-shaped channels.
- Glaciers create U-shaped valleys.
- Valleys usually have pleasant climates, making them good places to live.
- Water from rivers in valleys provides resources for human settlements.
Plains
- Plains are broad, flat landforms with little elevation change.
- Plains are made by factors such as water, ice, and magma.
- Plains are excellent farmland because the soil is fertile.
- Plains near seas/oceans are called coastal plains.
- Plains made by rivers, wind and erosion are called erosional plains.
- Plains cover about a third of Earth's land area.
Plateaus
- The text refers to a plateau, the Lasithi plateau in Crete Island, Greece, as an example of flat land.
- The sides of plateaus in picture B are called cliffs.
