Consider the following countries:
I. Bolivia
II. Brazil
III. Colombia
IV. Ecuador
V. Paraguay
VI. Venezuela
Andes mountains pass through how many of the above countries?

Correct Answer:

(d) Only five

Explanation of the Correct Answer:

The Andes Mountains, the longest continental mountain range in the world, extend along the western edge of South America, passing through seven countries: Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile, and Argentina.

Let’s analyze each of the countries mentioned:

1. Bolivia – Yes
   • The Altiplano Plateau, a high plain in the central Andes, spans much of Bolivia.
2. Brazil – No
   • Brazil is east of the Andes; it has highlands and plateaus but not the Andes.
3. Colombia – Yes
   • The Andes enter Colombia from Ecuador and split into three branches (Cordilleras).
4. Ecuador – Yes
   • The Andes run through the center of the country.
5. Paraguay – No
   • Located to the east of the Andes, Paraguay is part of the interior lowlands.
6. Venezuela – Yes
   • The Andean Cordillera begins in western Venezuela.

Why Other Options Are Incorrect:

• (a) Only two – Incorrect; at least five countries listed have the Andes.
• (b) Only three – Incorrect; five countries are correct.
• (c) Only four – Incorrect; one more (Venezuela) also has Andes.
• (d) Only five – Correct, as Brazil and Paraguay are not crossed by the Andes.

  • Length: ~7,000 km
  • Countries crossed: Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile, Argentina
  • Important features: Altiplano Plateau, Machu Picchu, Atacama Desert (rain shadow)
• Orogeny:
  • The Andes are formed due to the subduction of the Nazca Plate beneath the South American Plate.

Current Relevance:

• The Andes are central to climate patterns, hydroelectric power, biodiversity, and mineral resources in Latin America.
• Regions in the Andes are also prone to earthquakes and volcanic activity.
