Environment Of India Quiz: Trivia!

Chlorofluorocarbons (CFCs) are used for refrigeration purposes. CFCs are a type of synthetic compound that can absorb and release heat very efficiently, making them ideal for use in refrigeration systems. They are commonly used as refrigerants in air conditioning units, refrigerators, and freezers. CFCs have high stability and low toxicity, which makes them suitable for this application. However, it has been discovered that CFCs contribute to ozone depletion, and their use has been phased out in many countries due to environmental concerns.

The Montreal Protocol is an international treaty that aims to protect the ozone layer by phasing out the production and use of substances that deplete it, such as chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs). It was adopted in 1987 and has been successful in reducing the production and consumption of ozone-depleting substances worldwide. Therefore, the correct answer is Ozone Layer.

Haryana has the lowest sex ratio in India according to the census of 2011. This means that there are fewer females compared to males in the state. The sex ratio is an important indicator of gender equality and reflects the social and cultural dynamics of a region. The low sex ratio in Haryana may be attributed to factors such as gender discrimination, preference for male children, and practices like female feticide and infanticide.

The Amazon Rain Forest is known as "The lungs of the planet earth" because it produces approximately 20% of the world's oxygen. It is the largest tropical rainforest in the world, covering an area of about 5.5 million square kilometers. The dense vegetation in the Amazon Rain Forest absorbs carbon dioxide through photosynthesis and releases oxygen, making it vital for maintaining the Earth's oxygen levels. The forest also plays a crucial role in regulating the climate by storing large amounts of carbon dioxide, a greenhouse gas that contributes to global warming.

Ladakh is the correct answer because it is a region known for being the native place of the species of Yak (ox) and the Bharal. Yak and Bharal are commonly found in the high-altitude regions of Ladakh, where the climate and terrain are suitable for these species. Uttarakhand, Himachal Pradesh, and Tamil Nadu do not have the same geographical conditions as Ladakh, making Ladakh the most likely region for these species to be native to.

Thorn forests and scrubs have thick and small leaves to minimize evaporation. This is because these plants are typically found in arid and dry regions where water is scarce. The small size and thickness of the leaves help to reduce the surface area through which water can be lost through evaporation, thus conserving moisture. Additionally, the thick leaves also help to protect the plant from excessive heat and sunlight, further reducing water loss.

Humpback whales can produce the loudest sound among any living creatures. They are known for their complex and haunting songs, which can travel for long distances underwater. These songs are used for communication and mating purposes. The sound produced by humpback whales can reach up to 188 decibels, which is louder than a jet engine. This ability to produce such loud sounds is due to their large size and specialized vocal organs.

The Ganga-Brahmaputra Delta is famous for the occurrence of Mangrove forests in India. This delta is formed by the confluence of the Ganges and Brahmaputra rivers and is located in the states of West Bengal and Bangladesh. The delta region has a unique ecosystem that supports the growth of mangrove forests. Mangroves are salt-tolerant trees that thrive in coastal areas with brackish water. The Ganga-Brahmaputra Delta provides the perfect conditions for mangroves to flourish, making it a significant habitat for these unique and important ecosystems.

Brazil is considered to have the world's first sustainable bio-fuels economy because it has made significant advancements in the production and use of biofuels, particularly ethanol derived from sugarcane. Brazil has a long history of utilizing biofuels, with the government implementing policies and incentives to promote the use of ethanol as a renewable energy source. The country has a vast amount of arable land suitable for sugarcane cultivation, which has allowed Brazil to become a global leader in biofuel production. Additionally, Brazil's biofuel industry has contributed to job creation, energy security, and reduced greenhouse gas emissions.

Transport is the largest emitter of greenhouse gases in India because it includes emissions from vehicles such as cars, trucks, buses, and motorcycles. These vehicles run on fossil fuels like petrol and diesel, which release carbon dioxide and other greenhouse gases when burned. The high number of vehicles on Indian roads, coupled with inadequate public transportation infrastructure and a growing population, contribute to the significant emissions from the transport sector.

Water vapor is the most abundant Green House Gas (GHG) in the earth's atmosphere. It is present in large quantities due to the continuous evaporation of water from oceans, lakes, and other bodies of water. Water vapor plays a crucial role in the Earth's climate system as it acts as a greenhouse gas, trapping heat and contributing to the greenhouse effect. While carbon dioxide is also a significant greenhouse gas, water vapor surpasses it in terms of abundance in the Earth's atmosphere. Nitrogen Dioxide and Sulphur Dioxide are not greenhouse gases and do not contribute significantly to the greenhouse effect.

The atmosphere is located up to a height of 10 kms in the Polar latitudes. This is because the Polar regions experience colder temperatures and lower atmospheric pressure compared to other latitudes. As a result, the atmosphere is thinner and extends to a lower height in these regions.

The main contributors to e-waste in the world are refrigerators/freezers, washing machines, dishwashers (I), small household appliances such as toasters, coffee makers, irons, hairdryers (II), and personal computers, telephones, mobile phones, laptops, printers, scanners, photocopiers (III). Gas cylinders, chimneys, and home appliances (IV) are not considered electronic appliances and therefore not contributors to e-waste.

The correct answer is Ranganathittu Sanctuary. This sanctuary is visited by the endangered species Siberian Crane every year.

Rainwater harvesting is important because it helps to reduce the consumption of groundwater. By collecting, filtering, storing, and using rainwater, people can rely less on groundwater sources for various purposes, such as irrigation. This is especially crucial in areas where groundwater is limited or overused. Rainwater harvesting systems are being adopted by many people globally as a sustainable solution to conserve water resources and reduce the strain on groundwater reserves.
