Review Questions

• How does the Atlantic Ocean influence global climate patterns?
  • The Atlantic Ocean significantly influences global climate patterns through its currents, such as the Gulf Stream. This current transports warm water from the tropics to higher latitudes, which helps moderate temperatures in regions like Western Europe. Additionally, the ocean acts as a heat reservoir, impacting weather systems and contributing to phenomena like hurricanes and cyclones in the Atlantic basin.
• What are some key ecosystems found in the Atlantic Ocean, and how do they contribute to marine biodiversity?
  • The Atlantic Ocean is home to various key ecosystems, including coral reefs, deep-sea habitats, and estuaries. These ecosystems support a rich diversity of marine life by providing essential services such as breeding grounds for fish, nurseries for juvenile species, and food sources for a wide range of organisms. The health of these ecosystems is crucial for maintaining marine biodiversity and ensuring sustainable fisheries.
• Evaluate the economic importance of the Atlantic Ocean to coastal nations and discuss potential challenges they face.
  • The Atlantic Ocean is economically vital for coastal nations due to its role in shipping trade routes, fishing industries, and tourism. Countries bordering the Atlantic rely on its resources for jobs and revenue generation. However, challenges such as overfishing, pollution, and climate change threaten these economic benefits. Coastal nations must find sustainable ways to manage their marine resources while addressing these environmental issues to ensure long-term economic stability.
