Comparing Two World Regions

Overview

This is a self-contained, no-technology substitute packet in which high-school students compare two real world regions — the Sahara region of North Africa and the Amazon Basin of South America — using both physical geography (climate, landforms, rainfall) and human geography (population, settlement, and main economic activities). Working alone with a pencil, students read two short original profiles, study an original comparison figure, complete a compare-and-contrast, trace how physical features shape human activity (a cause/effect), distinguish fact from interpretation and opinion, evaluate a claim, and write an evidence-based comparison about which region's physical geography limits settlement more. The packet supports a ~50-minute standard version and a ~90-minute block version (the block adds a push/pull-factor and land-use profile and extended writing). Prompts are non-partisan and grounded in the evidence in the packet.

Accessible version of the student activity

The full student activity is reproduced below in plain, screen-reader-friendly HTML. It reflows on phones and at 200% zoom. Write your answers on the printed packet. Items marked [BLOCK] are for the ~90-minute version only.

Start (5 minutes) — Observe a region

A region is an area of the world that shares one or more common features. Two short descriptions: Region 1 — "A vast, hot desert of sand, rock, and gravel where rain almost never falls; days are scorching, nights can be cold, and most settlement clusters near scarce water." Region 2 — "A hot, wet lowland covered by the world's largest rainforest, drained by a giant river system, where thick vegetation and heavy rainfall shape daily life." (Type: original descriptions written for this packet.)

1. Write one thing you notice about how the two regions differ in climate (how wet or dry, hot or cool), and predict one way daily life or work might differ between them.
2. Why might a region's climate and landforms affect where people choose to live? Give one reason in your own words.

Build (10–15 minutes) — Read the profiles

Profile A — The Sahara region, North Africa (written for this packet)

Physical geography: the Sahara is one of the largest hot deserts on Earth, spanning much of North Africa. Its climate is hot and extremely dry — many areas get only a few centimeters of rain a year, days are very hot, and clear skies make nights turn cold. The land is sand dunes, bare rock, gravel plains, and scattered mountains, and water is the scarcest resource. Population & settlement: density is very low, and people cluster where water is available — at oases, along rivers such as the Nile at the region's edges, and near wells — while much of the interior is nearly empty. Main economic activities: pastoral herding (camels, goats, sheep), oasis farming of hardy crops such as dates, long-standing trade routes, and today oil, natural gas, and mineral extraction plus some desert tourism. (Type: original explanatory profile.)

Profile B — The Amazon Basin, South America (written for this packet)

Physical geography: the Amazon Basin is a huge lowland in northern South America drained by the Amazon River and its many tributaries, one of the largest river systems in the world by water volume. Its climate is hot and very wet (tropical), with heavy rainfall much of the year and high humidity, supporting the world's largest tropical rainforest over mostly flat terrain. Population & settlement: the deep rainforest has low density, but people commonly settle along the rivers, which act as natural highways; some large cities have grown at key points on the river system, and Indigenous communities have lived across the basin for a very long time. Main economic activities: fishing and river transport, gathering forest products, small-scale and commercial farming, logging, and mining; the rainforest is also globally important for biodiversity and carbon storage, which shapes debates over land use. (Type: original explanatory profile.)

Profile C — Land-use & push/pull factors [BLOCK]

An original summary. A push factor drives people away from a place; a pull factor draws them toward it. In the Sahara, extreme dryness and scarce water push permanent settlement away from the deep interior, while oases and river water pull people toward a few livable spots. In the Amazon Basin, dense forest and flooding can push settlement away from some interior areas, while rivers (for transport and fishing) and jobs in growing cities pull people toward the waterways. Land use differs: the Sahara supports mostly herding, oasis farming, and resource extraction; the Amazon supports fishing, farming, logging, and mining within or around the forest.

Word bank

region

an area that shares one or more common features, such as climate or landforms.

physical geography

the natural features of a place: climate, landforms, water, and vegetation.

human geography

how people live in a place: where they settle and how they work.

climate

the usual pattern of temperature and precipitation in a place over many years.

landform

a natural feature of the land's surface, such as a dune, plain, mountain, or river valley.

population density

how many people live in a given area of land.

settlement

a place where people live; also the pattern of where people choose to live.

oasis

a fertile spot in a desert where water is available at or near the surface.

arid

very dry; receiving little precipitation.

tropical

hot and typically wet; found near the Equator.

push factor

a condition that drives people away from a place.

pull factor

a condition that draws people toward a place.

fact

a statement that can be checked and shown true or false.

interpretation

an explanation of what evidence means; reasoned from facts.

opinion

a personal belief or preference; not proven by evidence.

3. Using Figure 1, fill in the two missing cells: yearly rainfall for the Sahara, and climate for the Amazon Basin.

Apply (20–25 minutes) — Analyze the region

4. Read the figure: (a) which region has the higher yearly rainfall? (b) in which region do people mainly settle along rivers? (c) name one economic activity listed for the Sahara that is not listed for the Amazon.
5. Compare — similarities and differences: give one physical point and one human point for a way the regions are similar and for a way they are different.
6. How do physical features shape human activity? Pick one region and, in 2–3 sentences, trace a chain: name a physical feature, explain how it affects where people live, and name one economic activity it helps make possible.
7. Cause and effect across regions: water shapes settlement in both regions but in opposite ways. In the Sahara water is scarce, so people ____; in the Amazon water is abundant in the rivers, so people ____. Use one detail from each profile.
8. Fact (F), interpretation (I), or opinion (O)? Mark each:
   • a) The Sahara receives very little rain, while the Amazon Basin receives a great deal.
   • b) Because water is so scarce in the Sahara, most people probably live near oases or rivers.
   • c) The Amazon rainforest is a far more beautiful place to live than the desert.
   • d) Rivers in the Amazon Basin are used for transport and fishing.
9. Evaluate a claim: a student claims "Climate is the only thing that matters for how people live in a region — landforms and rivers make no difference." Do the profiles support it? Choose: (A) Yes — the profiles say climate is the only factor; (B) No — the profiles show landforms and rivers also matter (Amazon rivers as transport routes; Sahara oases and mountains shape settlement), not climate alone; (C) The profiles never mention rivers or landforms. Then explain your choice with one detail from a profile.
10. [BLOCK] Using Profile C, name one push factor and one pull factor for settlement in either region, then explain in one sentence how these factors help explain where people live there.

Explain (10–20 minutes) — Claim, Evidence, Reasoning

Question 11. Which region's physical geography places the greater limit on where people can settle — the Sahara or the Amazon Basin? Write a claim that names one region, support it with two pieces of evidence from the profiles or Figure 1, then explain your reasoning. There is no single "right" region — argue from the evidence. Sentence stems: "The region whose physical geography places the greater limit on settlement is ______ because…"; "One piece of evidence is… (from Profile A / B / C or Figure 1)."; "A second piece of evidence is…"; "This evidence supports my claim because…"

[BLOCK] Extended writing: add a land-use analysis (name one main economic activity from each region and explain how the physical geography makes it possible), and a counter-consideration — name one reason someone might argue the other region's physical geography limits settlement more, then explain why you still hold your claim or how it changes.

Close (5 minutes) — ACE

• Articulate: explain in your own words what it means to compare two regions using physical and human geography.
• Connect: point to one line in a profile or one cell in Figure 1 that shows a physical feature, and one that shows a human activity shaped by it; name both.
• Extend: name one region near where you live (or another region you know) and give one way its physical geography shapes how people there live or work.

Continue (optional, ~15 minutes) — Early finisher

Design a settlement: pick one region and choose where you would build a new town. Using only the profiles and Figure 1, name where you would locate it and why — point to a physical feature (an oasis, a river, a mountain edge) and explain how it would support the people who live there, supported by one detail from the packet.

Turn in

Hand in the whole packet with your name, class period, and date, with questions 1–11 and the ACE box answered (skip [BLOCK] items if you did the standard version). Include the optional early-finisher task if you did it.
