FAQs on Ocean Currents Video Lecture - Geography Class 11 - Humanities/Arts
| 1. What are ocean currents and how do they form? |  |
Ans. Ocean currents are the continuous, directed movement of seawater. They are mainly formed by three factors: wind, temperature, and salinity. Winds blowing over the ocean surface create surface currents, while differences in temperature and salinity create density differences, leading to deep ocean currents.
| 2. How do ocean currents affect climate? | |
Ans. Ocean currents play a crucial role in regulating Earth's climate. They transport heat from the equator towards the poles, redistributing warmth and influencing regional temperature patterns. For example, the Gulf Stream carries warm water from the tropics to western Europe, resulting in milder climates compared to regions at similar latitudes.
| 3. What are the major ocean currents and where are they located? | |
Ans. Some major ocean currents include the Gulf Stream, the North Atlantic Drift, the California Current, the Kuroshio Current, and the Antarctic Circumpolar Current. The Gulf Stream flows along the eastern coast of the United States, the North Atlantic Drift influences Europe's climate, the California Current runs along the western coast of North America, the Kuroshio Current affects Japan's climate, and the Antarctic Circumpolar Current encircles Antarctica.
| 4. How do ocean currents impact marine life? | |
Ans. Ocean currents have a significant impact on marine life. They influence the distribution of nutrients, oxygen, and food particles, shaping ecosystems and determining the movement patterns of various marine species. Some species rely on specific currents for transportation, while others use currents to find food or reproduce.
| 5. What are the potential consequences of changes in ocean currents due to climate change? | |
Ans. Climate change can alter ocean currents, potentially leading to various consequences. Changes in ocean circulation patterns could disrupt marine ecosystems, affecting the distribution and abundance of species. Additionally, altered currents may impact weather patterns, including changes in rainfall and storm intensity, which can have cascading effects on both marine and terrestrial environments.
