FAQs on Ocean Circulation Waves Tides & Current Video Lecture - Geography for Class 7
| 1. What is ocean circulation? |  |
Ans. Ocean circulation refers to the movement of water in the world's oceans, including the surface currents driven by winds, the deep ocean currents driven by density differences, and the global conveyor belt system that circulates heat and nutrients around the globe.
| 2. How are waves formed in the ocean? | |
Ans. Waves in the ocean are formed by the transfer of energy from the wind to the water surface. As wind blows across the water, it creates friction, causing ripples to form. These ripples then grow into waves due to the continuous transfer of energy from the wind.
| 3. What causes tides in the ocean? | |
Ans. Tides in the ocean are primarily caused by the gravitational pull of the Moon and, to a lesser extent, the Sun. The gravitational force of the Moon creates a bulge in the water on the side of the Earth facing the Moon, resulting in a high tide. On the opposite side of the Earth, there is also a high tide due to the centrifugal force caused by the rotation of the Earth.
| 4. How do currents affect marine life? | |
Ans. Currents play a crucial role in shaping marine ecosystems and influencing the distribution and movement of marine life. They help transport nutrients, larvae, and other organisms, which can affect the feeding and reproductive patterns of marine organisms. Currents also influence the mixing of water masses, which can impact the availability of oxygen and other essential elements for marine life.
| 5. What is the significance of the global conveyor belt system? | |
Ans. The global conveyor belt system, also known as thermohaline circulation, plays a vital role in regulating Earth's climate. It transports heat from the tropics to the polar regions, helping to moderate temperature differences. Additionally, it transports nutrients and oxygen, affecting the distribution of marine life and influencing various climate patterns, such as the El Niño Southern Oscillation.
