The 3 R's of Recycling are Reduce, Reuse, and Recycle. This means that we should try to reduce the amount of waste we produce, reuse items whenever possible instead of throwing them away, and recycle materials that can be made into new products. By following these principles, we can help conserve resources, reduce pollution, and protect the environment.

Acid rain is a form of air pollution that occurs when emissions from burning fossil fuels, industrial processes, and other sources react with the atmosphere to produce sulfuric acid and nitric acid. These acidic compounds can be carried long distances by the wind, leading to transboundary pollution. Therefore, it is true that acid rain can become a problem in different countries due to this transboundary pollution.

Factories cause pollution by dumping chemicals into rivers and lakes. This practice contaminates the water sources, leading to water pollution and negatively impacting aquatic life. Chemicals released into the water can also seep into the soil, affecting plant life and potentially entering the food chain. This pollution can have detrimental effects on ecosystems and human health.

The Earth Day began in 1970. This day is observed annually on April 22nd to raise awareness about environmental issues and promote conservation. The first Earth Day in 1970 was a significant event that mobilized millions of people across the United States to demonstrate for a sustainable and healthy environment. Since then, Earth Day has become a global movement with various activities and initiatives focused on protecting the planet and promoting environmental responsibility.

Gaylord Nelson is the correct answer for the question "Who invented Earth Day?" Gaylord Nelson was a U.S. Senator who founded Earth Day in 1970. He was inspired to create a national day of environmental awareness after witnessing the devastating effects of an oil spill in Santa Barbara, California. Earth Day has since become a global event celebrated on April 22nd each year, promoting environmental protection and sustainability.

Each and every individual has a responsibility to protect the environment because it is a collective effort that requires everyone's participation. Each person's actions, no matter how small, can have a significant impact on the environment. By being conscious of our daily activities and making sustainable choices, such as reducing waste and conserving resources, we can contribute to the overall protection of the environment. It is not solely the responsibility of the government, NGOs, or specific environmental protectors, but rather a shared responsibility that starts with each and every individual.

The amount of glacial ice on Earth directly correlates to sea levels. Glacial ice is formed from compacted snow over thousands of years, and when it melts, it contributes to the rise in sea levels. As more glacial ice melts, the sea levels increase, posing a significant threat to coastal areas and low-lying islands. Therefore, the amount of glacial ice on Earth is closely linked to the fluctuation of sea levels.

Hydro energy refers to the generation of electricity using the force of running water, such as rivers or waterfalls. This renewable energy source harnesses the kinetic energy of moving water to drive turbines, which in turn generate electricity. It is a clean and sustainable form of energy that does not produce greenhouse gas emissions or contribute to air pollution. Hydro energy is widely used around the world and plays a significant role in meeting the global demand for electricity.

Exposure to radon gas is a well-known risk factor for developing lung cancer. Radon is a radioactive gas that is released from the decay of uranium in soil, rocks, and water. When inhaled, radon particles can damage the cells lining the lungs, leading to the development of cancer over time. Therefore, the correct answer is lung cancer.

Burning fossil fuels for energy is a major cause of acid rain. When fossil fuels such as coal, oil, and natural gas are burned, they release pollutants like sulfur dioxide and nitrogen oxides into the atmosphere. These pollutants then react with water, oxygen, and other chemicals to form sulfuric acid and nitric acid, which fall back to the Earth as acid rain. This acid rain can have harmful effects on the environment, including damaging forests, lakes, and buildings, and also contributing to the acidification of water bodies.

Clearing land for agriculture, ranching, and mining is a major cause of deforestation. When land is cleared for these purposes, it involves cutting down trees and removing vegetation, which results in the loss of forest cover. Agriculture requires large areas of land to grow crops and raise livestock, while mining involves the extraction of minerals and resources from the earth. Both activities often involve the destruction of forests to make way for these operations. This leads to habitat loss, biodiversity decline, and disruption of ecosystems, contributing to deforestation.

Fossil fuels are organic fuels derived from ancient plants and animals. This means that they are formed from the remains of plants and animals that lived millions of years ago. Over time, the remains were subjected to heat and pressure, which transformed them into fossil fuels such as coal, oil, and natural gas. These fuels are non-renewable resources and are widely used for energy production in society.

While tornadoes, volcanoes, and hurricanes are all examples of random natural disruptions, an annual wild fire is not. Annual wild fires occur predictably and are a natural part of certain ecosystems, such as grasslands or forests. They often serve as a necessary process for the renewal and regeneration of these ecosystems. Therefore, an annual wild fire is not considered a random natural disruption like the other options.

Sulfur dioxide and nitrogen oxide mix with water in the air to form acid rain. When fossil fuels are burned, they release these pollutants into the atmosphere. Sulfur dioxide is produced by burning coal and oil, while nitrogen oxide is produced from the combustion of fossil fuels in vehicles and power plants. These pollutants then react with water vapor in the air to form sulfuric acid and nitric acid, which fall back to the Earth's surface as acid rain. This acidic precipitation can have harmful effects on the environment, including damaging vegetation, contaminating water sources, and corroding buildings and infrastructure.

Glass can be recycled and remanufactured indefinitely without wearing out. Unlike other materials, glass does not degrade or lose its quality during the recycling process. It can be melted down and reshaped repeatedly without any loss in its physical or chemical properties. This makes glass a highly sustainable and environmentally friendly material, as it can be continuously reused without the need for additional raw materials.

The event that sparked Earth Day was an oil spill. This environmental disaster brought attention to the devastating effects of pollution on the planet, leading to increased awareness and activism for environmental conservation. Earth Day was subsequently established as a way to raise awareness and promote actions to protect the Earth and its natural resources.

Bio-diesel is the correct answer because it is an alternative fuel that is made from soya-beans, palm oil, and other plants. It is a renewable source of energy and can be used as a substitute for traditional diesel fuel. Bio-diesel is considered to be more environmentally friendly as it produces lower emissions compared to regular diesel fuel.

Greenhouse gases, such as carbon dioxide and methane, are essential for maintaining the Earth's temperature and making it habitable. These gases trap heat from the sun in the atmosphere, creating a natural greenhouse effect. Without them, the Earth would be too cold to support life. Therefore, greenhouse gases are necessary for keeping the Earth warm.

Radon is a radioactive gas that can accumulate in homes. It is colorless, odorless, and tasteless, making it difficult to detect without proper testing. Radon can seep into buildings through cracks in the foundation, walls, or floors, and can become trapped indoors, especially in poorly ventilated areas. Prolonged exposure to radon gas is a significant health risk, as it is the second leading cause of lung cancer after smoking. Therefore, it is crucial to regularly test for radon levels in homes and take necessary measures to mitigate its presence.

Earth's size does not cause periodic disruptions on Earth. The other factors listed - Earth's tilt, Earth's orbit, and Earth's wobble - all contribute to various natural phenomena such as seasons, climate patterns, and changes in the length of daylight throughout the year. However, Earth's size itself does not directly cause any periodic disruptions.
