Review Questions

• How does the Indian Ocean influence the climate of nearby regions?
  • The Indian Ocean significantly influences the climate of nearby regions through the monsoon winds that bring seasonal rainfall to countries like India and Bangladesh. The monsoons are critical for agriculture as they provide much-needed water during dry periods. This climatic pattern not only affects weather conditions but also has socio-economic implications for millions of people who rely on these rains for their livelihoods.
• Discuss the ecological significance of coral reefs in the Indian Ocean and their contribution to marine biodiversity.
  • Coral reefs in the Indian Ocean are among the most biodiverse ecosystems on Earth. They provide habitat for thousands of marine species, including fish, mollusks, and crustaceans. The health of these reefs is vital for local economies that depend on fishing and tourism. However, they face threats from climate change, pollution, and overfishing, making their preservation essential for maintaining marine biodiversity.
• Evaluate the impact of maritime trade routes in the Indian Ocean on global economics and politics.
  • Maritime trade routes in the Indian Ocean have historically been pivotal for global economics and politics due to their role in connecting major economies across continents. These routes facilitate the exchange of goods such as oil, spices, and textiles. Control over these routes can shift geopolitical power dynamics among nations. The strategic importance of ports along these routes has led to competition among countries for influence and access, significantly shaping international relations in recent decades.
