Q1 Difference between Continent & Country:
Continents are the seven largest pieces of land on Earth. Countries are smaller areas of land inside continents that have their own governments and borders.
Q2 Compass Rose Blank Labels:
E = East (Right)
W = West (Left)
Q4 Oceans Count:
There are 5 major oceans in the world.
Q3 Define "region" in own words:
(Answers will vary) A region is an area where things look similar. For example, a place where people speak the same language, eat similar food, or share the same hot weather.
1. Continent vs. Country: A continent is a huge block of land (7 on Earth); a country is a smaller, self-governing area inside a continent.
2. Region & Example: An area with shared characteristics. Examples: "The Middle East," "The Desert Region," "The Pacific Northwest."
PART 2: MAP READING & NAVIGATION
3. Africa East Travel: Students must write Indian Ocean.

🔑 STUDENT HANDBOOK: PAGE 1 (DO NOW: WATERWAYS)
Q1 Why land trade was difficult:
Moving heavy goods over dry land, deserts, and forests was very slow, expensive, and dangerous because there were no trucks or paved roads.
Q2 Two advantages of rivers:
1. Fresh water and wet fertile soil (silt) for growing food crops.
2. Natural "water highways" to float heavy goods easily on rafts and boats.
Q3 How Phoenicians got rich:
They built deep-water ports on the Mediterranean coast and sailed massive wooden ships to trade luxury items like purple dyes and timber with other countries.
Q4 Landlocked definition:
A country that is completely surrounded by dry land, with no direct access to oceans or seas.

Q1: River Valleys as "Natural Highways"
Boats can carry heavy goods long distances smoothly with river currents, bypassing the strain of dragging items over mountain trails or dry deserts.
Q2: Coastal vs. River Trade
River trade moves back and forth along one single stream flow. Coastal trade uses ships to navigate the open sea in any direction, connecting to many foreign countries.
Q3: Mountains & Deserts Double Effect
• HELP: Act as tall walls (shields) preventing foreign armies from marching in.
• HURT: Block easy overland paths, making trading with neighbor civilizations incredibly slow.
Trading Places: Professional Teacher Guide Page 2 of 2
Timestamp 03:45 QUESTION 3
How can a country's climate (weather patterns) give it a "comparative advantage"?
A. Cold weather makes boats sail ten times faster. B. Having the perfect warm weather to easily grow cash crops like coffee or sugar. C. Having no winds so storms can never start. D. Deserts are the best place to find wheat and rice.

Route Challenge 1: Delicate Silk
📝 Page 3 Challenge 1
🌊 Route 1: Sea Lanes
Takes 4 Months (Long)
Sails across open coastal sea networks. It is a long journey, but waters are calm and merchant vessels can drop anchor in safe island ports regularly.
Danger profile:
🟢 LOW RISK • Safe harbors • Smooth sailing
⛰️ Route 2: Mountain Pass
Takes 2 Months (Short)
Cuts straight across steep rocky mountain ridges. High cliffs have narrow paths, severe blinding snowstorms, and deep caves where bandits lie waiting.
Danger profile:
🔴 HIGH RISK • Snow blocks • Bandit ambush threat!
📝 Answer Page 3 Set 1: Which route protects fragile silk from bumpy mountain trails? Slide 5 of 10
Route Challenge 2: Heavy Gold Caravan
📝 Page 3 Challenge 2
🏜️ Route A: Short Desert Trek
Takes 15 Days (Very Fast)
🔥
Cuts straight through deep sand dunes in a straight line. It is incredibly quick, but there are **zero oases** or freshwater wells along the entire way.
Survival risk:
🔴 EXTREME RISK • Dehydration • Camel death threat
🌴 Route B: Oasis Caravan Route
Takes 30 Days (Slower)
🌴
A winding path through the desert that circles slightly. It takes twice as long, but it directly connects **three natural water oases** to refill water skins.
Survival risk:
🟢 LOW RISK • Steady water • Safe resting camps

Positioning Showdown
Comparing Locations
⚓ Venice (Coastal Sea Portal)
100% WATER ACCESS
Venice is located directly on a deep, sheltered saltwater lagoon of the Adriatic Sea.
• Ships can load and unload goods easily.
• Directly connected to Asia, Africa, & Europe.
👑 Outcome: Became one of the richest empires ever.
🏔️ Switzerland (Inland Mountains)
0% WATER ACCESS
Switzerland is completely landlocked, enclosed by the colossal, icy peaks of the Swiss Alps.
• Ships could not reach them.
• Mountain paths were completely blocked by snow.
❌ Outcome: Slower initial trading growth compared to Venice.

🔑 STUDENT HANDBOOK: PAGE 1 (DO NOW: WORLD SHAPING ROUTES)
Q1 Regions connected by the Silk Road:
It connected China (or Asia) with Europe.
Q2 Why West Africans traded gold for salt:
West Africa had plenty of gold but lacked salt deposits. They desperately needed salt to preserve their meats and survive, making salt as valuable as gold to them.
Q3 How natural geography determines what goods are traded:
Geography controls the resources a country starts with (soil, minerals, weather). If a country has natural gold mines or coastal access, they will trade those items with nations that lack them.
Justify: Silk is extremely fragile and delicate. Shaking it on bumpy, rocky mountain wagon trails (Route 2) would rip or damage it, and snowy trails make it wet. Sea lanes are smooth and protected.
🐪 CHALLENGE SET 2 (Sahara):
• Optimal Route: Route B (Oasis Route)
Justify: Even though Route B takes longer (30 days vs 15), desert heat is lethal. Drivers and camels cannot survive 15 days of zero water. Oasis stops ensure they can drink and stay alive.
Comparative advantage is when a nation's geography makes it cheap and easy to make a specific product. Climate plays a role by providing the perfect heat, sun, or rain to grow specialized crops (like coffee or sugarcane) without expensive greenhouses.
Q2: Venice vs. Switzerland
Venice had much more initial success. Being directly on the sea allowed merchant fleets to load cargo easily and sail directly to foreign markets, while landlocked Switzerland was blocked by towering Swiss Alps and frozen, dangerous mountain gaps.
Q3: Selected Trade Route & Cargo
• Silk Road: Carried delicate Chinese silk, paper, and valuable spices in exchange for European gold and glassware.
• Trans-Saharan: Carried North African mineral salt to West Africa in exchange for precious gold coins and bars.
