What is the primary source of energy for tidal power?

  1. Wind

  2. Sunlight

  3. Ocean Waves

  4. Tidal Currents


Correct Option: D
Explanation:

Tidal power harnesses the kinetic energy of moving tidal currents, which are caused by the gravitational pull of the moon and sun on the Earth's oceans.

Which type of tidal power generation system is commonly used in estuaries and rivers?

  1. Barrage

  2. Tidal Stream Generator

  3. Lagoon

  4. Bulb Turbine


Correct Option: B
Explanation:

Tidal stream generators are placed in areas with strong tidal currents to capture the kinetic energy of the flowing water and convert it into electricity.

What is the main advantage of tidal power generation compared to other renewable energy sources?

  1. Predictability

  2. Low Maintenance

  3. High Efficiency

  4. Large-Scale Potential


Correct Option: A
Explanation:

Tidal power generation is predictable because the tides are influenced by the gravitational forces of the moon and sun, allowing for accurate forecasting of energy production.

Which country is a global leader in tidal power generation?

  1. United Kingdom

  2. United States

  3. China

  4. France


Correct Option: A
Explanation:

The United Kingdom has been at the forefront of tidal power development, with several operational tidal power plants and ongoing research projects.

What is the primary environmental concern associated with tidal power generation?

  1. Greenhouse Gas Emissions

  2. Habitat Disruption

  3. Visual Impact

  4. Noise Pollution


Correct Option: B
Explanation:

Tidal power generation can potentially disrupt marine habitats and affect marine life, particularly in areas with sensitive ecosystems.

Which type of tidal power generation system involves constructing a large basin that is filled and emptied by the tides?

  1. Barrage

  2. Tidal Stream Generator

  3. Lagoon

  4. Bulb Turbine


Correct Option: C
Explanation:

Lagoon tidal power systems involve constructing a large basin or lagoon that is filled and emptied by the tides, generating electricity as the water flows in and out.

What is the term used to describe the difference in height between high tide and low tide?

  1. Tidal Range

  2. Tidal Current

  3. Tidal Surge

  4. Tidal Bore


Correct Option: A
Explanation:

Tidal range refers to the vertical difference between the highest and lowest levels of the tide during a tidal cycle.

Which type of tidal power generation system utilizes a bulb-shaped turbine to capture the energy of tidal currents?

  1. Barrage

  2. Tidal Stream Generator

  3. Lagoon

  4. Bulb Turbine


Correct Option: D
Explanation:

Bulb turbines are installed in tidal stream generators to capture the kinetic energy of tidal currents and convert it into electricity.

What is the name of the world's largest tidal power plant?

  1. Sihwa Lake Tidal Power Station

  2. La Rance Tidal Power Station

  3. Annapolis Royal Generating Station

  4. Jiangxia Tidal Power Station


Correct Option: A
Explanation:

The Sihwa Lake Tidal Power Station in South Korea is the world's largest tidal power plant, with a capacity of 254 megawatts.

Which factor significantly influences the amount of tidal energy that can be harnessed at a particular location?

  1. Tidal Range

  2. Wave Height

  3. Wind Speed

  4. Solar Radiation


Correct Option: A
Explanation:

Tidal range plays a crucial role in determining the amount of tidal energy that can be harnessed, as a larger tidal range results in stronger tidal currents and higher energy potential.

What is the term used to describe a large wave caused by a sudden displacement of water, often associated with earthquakes or landslides?

  1. Tidal Range

  2. Tidal Current

  3. Tidal Surge

  4. Tidal Bore


Correct Option: C
Explanation:

Tidal surge refers to a large wave caused by a sudden displacement of water, typically associated with seismic activity or landslides.

Which type of tidal power generation system involves constructing a dam across a tidal estuary?

  1. Barrage

  2. Tidal Stream Generator

  3. Lagoon

  4. Bulb Turbine


Correct Option: A
Explanation:

Tidal barrages are constructed across tidal estuaries to create a difference in water level, allowing for the generation of electricity as the tide rises and falls.

What is the primary environmental benefit of tidal power generation?

  1. Reduced Greenhouse Gas Emissions

  2. Habitat Preservation

  3. Increased Biodiversity

  4. Improved Water Quality


Correct Option: A
Explanation:

Tidal power generation is a clean and renewable energy source that does not produce greenhouse gases, contributing to the reduction of carbon emissions.

Which country has the highest installed capacity of tidal power in the world?

  1. United Kingdom

  2. China

  3. France

  4. South Korea


Correct Option: B
Explanation:

China has the highest installed capacity of tidal power in the world, with several large-scale tidal power plants in operation.

What is the term used to describe the rapid rise of water level caused by the incoming tide?

  1. Tidal Range

  2. Tidal Current

  3. Tidal Surge

  4. Tidal Bore


Correct Option: D
Explanation:

Tidal bore refers to the rapid rise of water level caused by the incoming tide, often forming a wave that travels upstream in rivers or estuaries.
