FAQs on Waves and Tides Video Lecture - Geography Class 11 - Humanities/Arts
| 1. What causes waves in the ocean? |  |
Ans. Waves in the ocean are primarily caused by the wind blowing across the surface of the water. The friction between the air and the water creates ripples, which then develop into larger waves. Other factors such as the gravitational pull of the moon and the sun, as well as underwater earthquakes and volcanic eruptions, can also generate waves.
| 2. How do waves transfer energy? | |
Ans. Waves transfer energy through the oscillation of particles in a medium, such as water. As a wave passes through the water, the particles move in a circular or elliptical motion, but their overall position remains relatively unchanged. This transfer of energy is known as mechanical wave propagation.
| 3. What is the difference between ocean tides and waves? | |
Ans. Ocean tides and waves are both related to the movement of water, but they have distinct causes and characteristics. Tides are primarily caused by the gravitational pull of the moon and the sun, resulting in the rising and falling of water levels along coastlines. Waves, on the other hand, are primarily caused by wind or other disturbances at the surface of the water, resulting in the movement of water particles up and down or back and forth.
| 4. How do tides affect coastal ecosystems? | |
Ans. Tides play a crucial role in shaping and influencing coastal ecosystems. The changing water levels associated with tides create unique habitats for various species of plants and animals, including salt marshes, tide pools, and mangrove forests. Tidal currents also help distribute nutrients and oxygen, impacting the growth and survival of marine organisms.
| 5. What are some popular recreational activities associated with waves and tides? | |
Ans. Waves and tides offer numerous recreational activities for people to enjoy. Surfing, boogie boarding, and bodyboarding are popular water sports that rely on ocean waves for thrill and excitement. Tidal pools provide opportunities for exploring marine life during low tides, while activities such as beachcombing, beach volleyball, and sunbathing are commonly enjoyed along coastal areas influenced by tides.
