Name the shipping canal joining Pacific and Atlantic Oceans.
Show Hint
Don't confuse it with the Suez Canal, which is located in Egypt (connecting the Mediterranean and Red Seas).
Solution and Explanation
• Shipping canals are artificial waterways constructed to create shorter maritime routes.
• They significantly reduce the time and cost of transporting goods across the globe.
Step 1: Identify the narrow land bridge
Point D is located at the narrow isthmus of Central America. This is the geographical point that connects the continents of North America and South America.
Step 2: Identify the canal through the isthmus
The Panama Canal was constructed across this isthmus to connect the Atlantic Ocean (via the Caribbean Sea) and the Pacific Ocean. It was opened in 1914 and uses a system of locks to move ships across the higher terrain of the interior.
Step 3: Analyse its trade significance
The canal saves ships approximately \( 13,000\ km \) of travel by avoiding the long and dangerous journey around the southern tip of South America (Cape Horn). It is a cornerstone of world trade, particularly for traffic between the eastern USA and Asia.

Hunting and Food Gathering
The earliest human beings depended on their immediate environment for their sustenance. They subsisted on: (a) animals which they hunted; and (b) the edible plants which they gathered from forests in the vicinity. Primitive societies depended on wild animals. People located in very cold and extremely hot climates survived on hunting. The people in the coastal areas still catch fish though fishing has experienced modernisation due to technological development. Many species, now have become extinct or endangered due to illegal hunting (poaching). The early hunters used primitive tools made of stones, twigs or arrows so the number of animals killed was limited. Gathering and hunting are the oldest economic activity known. These are carried out at different levels with different orientations. Gathering is practised in regions with harsh climatic conditions. It often involves primitive societies, who extract both plants and animals to satisfy their needs for food, shelter and clothing. This type of activity requires a small amount of capital investment and operates at very low levels of technology. The yield per person is very low and little or no surplus is produced.- Examine the role of climate, water availability, and soil fertility on the distribution of world population.
