About 9 minutes · 3 reading + 6 practice and checks
Time includes reading, practice, and questions. Extra videos or further study are optional.

A fictional region atlas explanation linking landforms, settlement, climate, resources and transport, with a comparison that avoids geographic determinism.

Keep your working files in your own notebook or software. Save a private description, checklist, and work link in My Proof.

What to include

  • Scale/location record.
  • Drainage and divide explanation.
  • Weather/climate comparison.
  • Multi-factor settlement and movement network.
  • Final atlas with count/rate comparisons and missing evidence.

Review and revise

Use these criteria to check your work and choose what to improve.

  • Distance and coordinates use the stated scale/convention.
  • Watershed and climate records preserve outlets, time windows and units.
  • Settlement/network explanation considers access and investment without stereotyping.
  • Final comparison uses correct denominators and names missing causal evidence.

The idea in everyday life

Fictional terrain card: Ridge R divides west/east slopes. West slope→Creek W→River J→Bay B. East slope→Creek E→Lake L. Port lies beside River J. Elevation points along W are 300, 180 and 40 m toward J.

The idea

A watershed is land draining to a common outlet. A divide separates drainage areas; a political border does not automatically do so.

Connect landforms and water — supplied practice

A watershed is land draining to a common outlet. A divide separates drainage areas; a political border does not automatically do so.

Fictional terrain card: Ridge R divides west/east slopes. West slope→Creek W→River J→Bay B. East slope→Creek E→Lake L. Port lies beside River J. Elevation points along W are 300, 180 and 40 m toward J.

  1. 1. Step 1

    Follow the supplied west-side arrows.

    You should see: West slope drains through W and J to B.

  2. 2. Step 2

    Follow the east side independently.

    You should see: East slope drains through E to L, outside the supplied Bay B basin.

  3. 3. Step 3

    Check the west elevation sequence.

    You should see: 300→180→40 m is downslope in the stated direction.

  4. 4. Step 4

    Annotate the basin and a human-use question.

    You should see: Include west slope, W and J in the B basin; ask how upstream land use could affect Port water quality, without asserting contamination.

Now change one thing

Add Stream S on the east slope with an explicitly supplied connection S→J→B. Enter B or L for its outlet.

Your work

What to finish

A labeled drainage chain and basin boundary.

Common mistake

Watch for this

Using a town border as a drainage divide.

How can I tell I understand it?

Trace each supplied drainage connection to its outlet and revise a basin membership claim when a connection changes.
