Explanation:

Tidal energy is a form of renewable energy that is generated by the movement of tides. It is one of the least exploited sources of energy, but it has the potential to make a significant contribution to the world's energy needs. Tidal energy is generated by building dams at narrow openings of the sea.

How does it work?

When the tide comes in, water is allowed to flow into a reservoir through turbines. The turbines then spin, generating electricity. When the tide goes out, the water flows back out of the reservoir, again turning the turbines and generating electricity.

Advantages of Tidal Energy:

- Tidal energy is a renewable source of energy that is not dependent on fossil fuels. It does not produce any harmful pollutants or greenhouse gases, making it an environmentally friendly source of energy.

- Tidal energy is predictable and reliable. Tides are caused by the gravitational pull of the moon and the sun, and their patterns can be accurately predicted. This means that tidal energy can be harnessed consistently, unlike wind or solar energy, which can be unpredictable.

- Tidal energy is a constant source of energy. Unlike wind or solar energy, which are intermittent, tidal energy is generated continuously, making it a reliable source of energy.

Disadvantages of Tidal Energy:

- The construction of tidal energy plants can be expensive and disruptive to marine life. The building of dams can create barriers for fish and other marine animals, disrupting their migration patterns.

- Tidal energy plants can only operate in areas where there are large tidal differences. This limits the areas where tidal energy can be harnessed.

- Tidal energy plants can be affected by extreme weather conditions, such as storms and hurricanes, which can damage the turbines and other equipment.

Conclusion:

Tidal energy has the potential to make a significant contribution to the world's energy needs. It is a reliable and predictable source of energy that is environmentally friendly. However, the construction and operation of tidal energy plants must be carefully managed to minimize the impact on marine life and to ensure that the plants can operate safely and efficiently.

For example, the Pacific Ocean is connected to the Atlantic Ocean through the Panama Canal, and the Arctic Ocean is connected to the Atlantic Ocean through the Greenland Sea.

Conclusion:
Based on the analysis of the statements, we can conclude that statement 1 is false and statement 2 is true. Therefore, the correct answer is option 'B' - 2 only.

Tropical Deciduous Forests and Coniferous Trees in India

Introduction:
India is known for its rich biodiversity and diverse forest cover. Tropical Deciduous Forests and Coniferous Trees are two of the major types of forests found in India.

Tropical Deciduous Forests:
Tropical Deciduous Forests, also known as Monsoon Forests, are the most widespread forest in India. These forests are found in regions with a distinct wet and dry season. The trees shed their leaves during the dry season to conserve water and grow new leaves during the wet season. Some of the common trees found in these forests are Sal, Teak, Neem, Mahua, and Bamboo.

Coniferous Trees:
Coniferous Trees are a type of evergreen tree that produce cones instead of flowers. These trees are found in temperate regions with cold winters and mild summers. In India, the varieties of coniferous trees found in temperate forests are Pine, Silver Fir, Spruce, and Cedar.

Correct Statement:
Both statements are correct. Tropical Deciduous Forests are the most widespread forest in India. Coniferous Trees, including Pine, Silver Fir, Spruce, and Cedar, are found in temperate forests in India.

To be classified as a dwarf planet, an astronomical object needs to meet certain conditions. Let's discuss each condition in detail:

1. Mass enough to assume a nearly round shape:
- The first condition for an object to be considered a dwarf planet is that it must have enough mass to assume a nearly round shape. This means that the object's gravity should be strong enough to pull it into a spherical or spheroidal shape.
- Spherical or spheroidal shapes are formed when an object's gravity pulls it equally in all directions, resulting in a balanced shape. This is why planets, including dwarf planets, are generally round.
- An object that does not have enough mass to pull itself into a round shape, like many asteroids or irregularly shaped rocks, would not be classified as a dwarf planet.

2. Should not be a moon:
- The second condition for an object to be considered a dwarf planet is that it should not be a moon. Moons are natural satellites that orbit planets or other celestial bodies.
- While moons can be spherical or spheroidal in shape, they do not meet the definition of a dwarf planet because they orbit around larger bodies.
- For example, the Moon is not classified as a dwarf planet because it orbits around the Earth.

3. Has cleared the neighbourhood around its orbit:
- The third condition for an object to be considered a dwarf planet is that it must have cleared the neighbourhood around its orbit.
- This condition refers to the ability of an object to dominate its orbit by clearing out debris, such as smaller objects or asteroids, from its path.
- Planets and dwarf planets have enough gravitational influence to either absorb or deflect other objects in their orbit, clearing the area around them.
- Objects that have not cleared their orbit, such as asteroids or comets, are not considered dwarf planets.

Based on the above conditions, the correct answer is option 'A' - 1 and 2 only. The object must have enough mass to assume a nearly round shape and should not be a moon. The condition of clearing its orbit (condition 3) is not necessary for an object to be classified as a dwarf planet.

Renewable resources are resources that can be replenished or reproduced naturally within a relatively short period of time. These resources are considered sustainable because their availability is not limited and they can be used indefinitely without depleting their supply. Some examples of renewable resources include solar energy, wind energy, hydropower, biomass, and geothermal energy.

Renewable resources are commonly contrasted with non-renewable resources, which are finite in supply and cannot be replenished once they are depleted. Non-renewable resources, such as fossil fuels (coal, oil, and natural gas), minerals, and metals, take millions of years to form and cannot be replaced within a human lifespan.

The characteristics of renewable resources that make them sustainable and environmentally friendly are as follows:

1. Natural replenishment: Renewable resources have the ability to regenerate or replenish themselves over time. For example, solar energy is constantly being produced by the sun, wind energy is generated by the movement of air masses, and hydropower is generated by the water cycle.

2. Low environmental impact: Renewable resources generally have a lower impact on the environment compared to non-renewable resources. For instance, using solar panels to generate electricity produces no greenhouse gas emissions, while burning fossil fuels for energy results in the release of carbon dioxide and other pollutants.

3. Reduced dependence on non-renewable resources: Utilizing renewable resources helps to reduce our reliance on non-renewable resources, which are finite in supply. This can help to mitigate the negative environmental and economic consequences associated with the extraction and use of non-renewable resources.

4. Potential for local production: Many renewable resources can be harnessed at a local level, allowing communities to generate their own energy and become more self-sufficient. This decentralization of energy production can enhance energy security and reduce dependence on centralized power grids.

Overall, renewable resources play a significant role in promoting sustainable development and addressing global challenges such as climate change and energy security. By harnessing these resources and transitioning to a renewable energy economy, we can create a more sustainable and resilient future.

Deforestation is the incorrect answer because it does not contribute to the conservation of natural resources. In fact, deforestation is the opposite of conservation as it involves the clearing or removal of forests or trees, leading to the depletion of natural resources. Let's discuss this in more detail.

1. Preventing wastage:
- One effective way to conserve natural resources is by preventing wastage. This includes reducing, reusing, and recycling materials to minimize the use of resources and decrease the amount of waste generated.
- By practicing responsible consumption and adopting sustainable habits, individuals and businesses can help conserve natural resources.

2. Save Water:
- Water conservation is crucial for the sustainable use of this valuable resource. By adopting water-saving measures such as fixing leaks, using efficient irrigation systems, and practicing responsible water usage, we can conserve water resources.
- Conserving water not only helps preserve freshwater sources but also reduces energy consumption associated with water treatment and distribution.

3. Deforestation:
- Deforestation refers to the clearance of forests or trees, usually for the purpose of agriculture, urbanization, or logging. This activity leads to the loss of forest ecosystems, biodiversity, and valuable natural resources.
- Deforestation contributes to environmental degradation, soil erosion, loss of habitat for wildlife, and increased greenhouse gas emissions. It disrupts the natural balance of ecosystems and negatively impacts the availability of resources such as timber, fuelwood, and medicinal plants.

4. Afforestation:
- Afforestation refers to the process of establishing forests in areas where there were none before. It involves planting trees and nurturing their growth.
- Afforestation is an effective way to conserve natural resources as it helps restore ecosystems, prevent soil erosion, enhance biodiversity, and mitigate climate change by sequestering carbon dioxide.
- Forests provide numerous benefits, including the provision of timber, fuelwood, food, and medicinal plants. They also regulate water cycles, maintain soil fertility, and provide habitat for a wide range of species.

In conclusion, while preventing wastage, saving water, and afforestation are effective ways to conserve natural resources, deforestation is an activity that depletes these resources. It is essential to prioritize sustainable practices and protect our natural resources for the well-being of current and future generations.

In 1993, the industry that was de-reserved was the mining of copper and zinc. This means that the government relaxed its control over this industry and allowed private players to participate and invest in it. The de-reservation of this industry was a significant step towards liberalization and opening up of the Indian economy.

The de-reservation of the mining of copper and zinc industry had several implications and benefits for the Indian economy:

Promotion of Private Investment:
- The de-reservation allowed private players to invest in the mining of copper and zinc industry, encouraging competition and promoting private sector participation.
- This led to increased investment in the industry, which resulted in technological advancements and improved productivity.

Economic Growth:
- The mining of copper and zinc industry plays a crucial role in the Indian economy as these minerals are essential for various industries like construction, manufacturing, and infrastructure development.
- With the de-reservation, the industry witnessed growth, leading to increased production and availability of these minerals, which in turn contributed to the overall economic growth of the country.

Job Creation:
- The de-reservation of the industry created employment opportunities as private players expanded their operations and hired more workforce.
- This helped in reducing unemployment and improving the livelihoods of people associated with the mining sector.

Efficiency and Competitiveness:
- Prior to the de-reservation, the mining of copper and zinc industry was largely controlled by government-owned companies.
- The entry of private players brought in market competition, leading to increased efficiency and competitiveness in the industry.
- Private players often bring in new technologies and management practices, which can result in improved productivity and cost-effectiveness.

Overall, the de-reservation of the mining of copper and zinc industry in 1993 was a significant step towards liberalization and opening up of the Indian economy. It promoted private investment, economic growth, job creation, and improved efficiency and competitiveness in the industry.

Overview of Deciduous Forests
Deciduous forests are characterized by trees that shed their leaves seasonally, adapting to changing climate conditions. The statements provided discuss key features of these forests.
Analysis of Statement 1
- Rainfall Range: Statement 1 claims that deciduous forests are found in regions where rainfall is between 70 and 200 cm.
- Correctness: This statement is somewhat misleading. While deciduous forests do require significant rainfall, the typical range is more accurately around 75 to 150 cm for moist deciduous forests, and they can tolerate slightly lower amounts in dry deciduous forests. Thus, it does not fully capture the specific range for all types of deciduous forests.
Analysis of Statement 2
- Classification Based on Water Availability: Statement 2 asserts that deciduous forests are divided into moist and dry deciduous types based on the availability of water.
- Correctness: This statement is accurate. Moist deciduous forests are typically found in regions with higher rainfall and are rich in biodiversity, while dry deciduous forests endure longer dry periods and have a different set of flora and fauna adapted to these conditions.
Conclusion
Given the analysis:
- Statement 1 is not entirely correct due to the ambiguity in the rainfall range.
- Statement 2 is correct as it accurately describes the classification based on water availability.
Thus, the correct answer is b) Only 2.
