Geography · Grades 4–7
Landforms and physical processes
A landform is a feature; a process helps create or change it.
Understand the idea
Distinguish shape and process
A landform is a feature; a process helps create or change it.
Trace material
Weathering breaks material down; erosion transports it; deposition leaves it elsewhere.
Use evidence over appearance
A single image may not establish how a feature formed.
Worked examples

erosion

deposition
Try it yourself
A river's source is

- the deepest ocean trench
- every point where it floods
A river's mouth is

- always the highest mountain
- where it enters another body of water
- the river's northernmost point
Explain the difference between weathering and erosion.
