A. Major Oceans & Marginal Seas:

• Pacific Ocean: Largest and deepest ocean; contains the Mariana Trench and the Pacific Ring of Fire.
• Atlantic Ocean: S-shaped ocean; busiest commercial shipping highway; contains the Mid-Atlantic Ridge.
• Indian Ocean: Only ocean named after a country; bordered by Asia, Africa, and Australia.
• Marginal Seas:
  • Mediterranean Sea: Enclosed sea separating Europe and Africa.
  • Red Sea: Narrow sea separating Africa and the Arabian Peninsula, linked to the Mediterranean via the Suez Canal.
  • Caspian Sea: World\'s largest inland body of water (saline lake).
  • Caribbean Sea: Tropical sea east of Central America.

B. Crucial Straits and Gulfs:

• Strait of Gibraltar: Narrow maritime strait connecting the Atlantic Ocean with the Mediterranean Sea, separating Spain (Europe) from Morocco (Africa).
• Strait of Malacca: Vital commercial choke-point connecting the Indian Ocean with the South China Sea, between Malaysia and Sumatra (Indonesia).
• Bering Strait: Narrow strait separating Asia (Russia) from North America (Alaska).
• Gulf of Mexico: Large oceanic gulf bounded by North America, Mexico, and Cuba.
• Persian Gulf: Strategic gulf between the Arabian Peninsula and Iran, shipping lane for world petroleum.

A. Major Mountain Ranges:

• The Himalayas (Asia): Young fold mountains containing the world\'s highest summit: Mount Everest ($8,848.86\text{ m}$).
• The Andes (South America): The longest continental mountain chain in the world ($7,000\text{ km}$), running along the entire western coast of South America (highest peak: *Aconcagua*).
• The Rocky Mountains (North America): Major cordillera stretching across western Canada and the United States.
• The Alps (Europe): Major European mountain system (highest peak: *Mont Blanc*).
• The Urals (Russia): Low ancient mountain chain marking the traditional geographical boundary separating Europe from Asia.

B. Major Plateaus:

• Tibetan Plateau (Asia): Highest and largest plateau on Earth (elevation $> 4,500\text{ m}$), nicknamed the "Roof of the World".
• Deccan Plateau (India): Triangular volcanic basalt plateau covering southern India.
• Colorado Plateau (North America): Arid plateau famous for the Grand Canyon cut by the Colorado River.

C. Major World Rivers:

• The Nile (Africa): Longest river in the world ($6,650\text{ km}$), flowing north into the Mediterranean Sea.
• The Amazon (South America): World\'s largest river by water discharge volume and drainage basin, flowing east across Brazil into the Atlantic.
• The Mississippi-Missouri (North America): Largest river system in North America, forming a bird\'s-foot delta in the Gulf of Mexico.
• The Yangtze / Chang Jiang (Asia): Longest river in Asia ($6,300\text{ km}$), flowing eastward across China into the East China Sea.

A. Standard Global Lines to Plot:

• Equator ($0^\circ$): Traverses northern South America (Ecuador, Colombia, Brazil), Central Africa (Congo, Kenya), and Indonesia.
• Tropic of Cancer ($23.5^\circ\text{ N}$): Passes through Mexico, Sahara (Egypt), Saudi Arabia, India (Gujarat, Rajasthan, MP, Chhattisgarh, Jharkhand, West Bengal, Tripura, Mizoram), and southern China.
• Tropic of Capricorn ($23.5^\circ\text{ S}$): Passes through northern Chile/Argentina/Brazil, Southern Africa (Namibia, South Africa, Mozambique), and Australia.
• Prime Meridian ($0^\circ\text{ Longitude}$): Runs through Greenwich (UK), France, Spain, Algeria, Mali, and Ghana.
• International Date Line ($180^\circ$): Runs through the Pacific Ocean, zig-zagging around the Aleutians and Fiji.

B. Standard Cartographic Color Conventions:

• Blue: Water bodies (Oceans, seas, gulfs, lakes, and rivers).
• Brown: Mountains, mountain peaks (triangles $\blacktriangle$), and hilly uplands.
• Yellow / Orange: Plateaus and arid semi-desert regions.
• Green: Lowlands, river plains, deltas, and agricultural plains.
