SSC CGL Tier-I Exam: Geography And Science Quiz!

In the troposphere layer, the temperature decreases with increasing altitude. This phenomenon is known as the lapse rate. The correct answer states that the temperature decreases at a rate of 1°C for every 165m of height. This means that for every 165 meters of upward movement in the troposphere, the temperature drops by 1 degree Celsius.

Extra-tropical cyclones can originate over both land and sea because they are large-scale weather systems that form in the mid-latitudes. These cyclones are often associated with fronts and can develop over areas where there is a significant contrast in temperature and moisture between the land and sea. As warm and cold air masses interact, they create the conditions necessary for the formation of these cyclones. Therefore, extra-tropical cyclones can form over both land and sea, making the answer "Land and Sea both" correct.

Chlorofluorocarbons (CFCs) gas is used in refrigerators. CFCs were commonly used as refrigerants in older models of refrigerators and air conditioners. However, due to their harmful effects on the ozone layer, the use of CFCs has been phased out and replaced with more environmentally friendly alternatives.

The River Mekong passes through China, Cambodia, and Thailand. This can be inferred from the given options, as the only answer choice that includes all three countries is "China, Cambodia, and Thailand."

The Kiel Canal connects the North Sea to the Baltic Sea.

China is the largest tea producing nation because it has a long history and tradition of tea cultivation and consumption. It has vast tea plantations and a large workforce dedicated to tea production. China's diverse climate and geography provide favorable conditions for growing different types of tea. The country is known for producing a wide variety of teas, including green tea, black tea, oolong tea, and white tea. China's tea industry is well-established and has a significant impact on its economy, making it the top tea-producing nation globally.

The correct answer is France and Germany. The Maginot Line was a defensive line of fortifications built by France along its border with Germany in the 1930s. It was designed to prevent any future invasions from Germany and to protect France from potential attacks. The line consisted of a series of underground bunkers, artillery positions, and obstacles, but it ultimately failed to stop the German invasion during World War II.

Sodium thiosulphate is used in photography as a fixing agent. After the film is exposed to light, it is developed using chemicals like sodium carbonate or sodium sulphate. However, these chemicals only develop the image temporarily. To make the image permanent, it needs to be fixed using sodium thiosulphate. This chemical removes the unexposed silver halide molecules from the film, preventing further exposure to light and ensuring the image remains intact. Therefore, sodium thiosulphate is the correct answer for the chemical used in photography.

All of the listed gases, including sulphur dioxide, carbon monoxide, and oxides of nitrogen, are inhaled by humans on traffic roads. These gases are produced as byproducts of burning fossil fuels in vehicles and are released into the air. Inhaling these gases can have harmful effects on human health, including respiratory problems and increased risk of cardiovascular diseases. Therefore, it is important to reduce vehicle emissions and improve air quality to minimize the exposure to these gases.

Schleiden and Schwann are credited with propounding the cell theory. Matthias Schleiden, a botanist, concluded that all plants are made up of cells, while Theodor Schwann, a zoologist, extended this idea to animals and stated that all living organisms are composed of cells. Their combined work laid the foundation for the cell theory, which states that cells are the basic structural and functional units of all living organisms.

Carbon dioxide is used in fire extinguishers because it is a non-flammable gas that displaces oxygen, effectively suffocating the fire. When carbon dioxide is released onto a fire, it creates a blanket of gas that reduces the oxygen levels, making it difficult for the fire to continue burning. Additionally, carbon dioxide is also effective in cooling down the fire, further aiding in extinguishing it.

Both AIDS and Gonorrhea are sexually transmitted diseases. AIDS is caused by the human immunodeficiency virus (HIV) and can be transmitted through sexual contact, as well as through blood transfusions, sharing needles, and from mother to child during childbirth or breastfeeding. Gonorrhea is a bacterial infection that is primarily transmitted through sexual contact with an infected person. Both diseases can have serious health consequences if left untreated, highlighting the importance of practicing safe sex and getting tested regularly.

The correct answer is option 1, 4, 2, 3. This means that the correct match for the Biosphere Reserve and its location in the States/UT is as follows: Similipal - Odisha, Dibru-Saikhowa - Assam, Dehang Debang - Arunachal Pradesh, and Nokrek - Meghalaya.

Goa is the most urbanized state in India because it has the highest percentage of its population living in urban areas compared to the other options. Urbanization refers to the process of increasing the proportion of people living in urban areas as opposed to rural areas. While Maharashtra, Karnataka, and Tamil Nadu are also highly urbanized states, Goa has the highest urbanization rate.

Silicon is required for solar energy conversion because it is a semiconductor material that has the ability to absorb and convert sunlight into electricity. It is the most commonly used material in solar panels due to its high efficiency in converting solar energy into usable electricity. Silicon's unique properties allow it to create an electric field when exposed to sunlight, which leads to the generation of an electrical current. This makes silicon an essential element for harnessing solar energy and producing renewable electricity.

Tungsten's chemical symbol is W.

Corbett is not part of the World Network of Biosphere Reserves based on the UNESCO Man and the Biosphere (MAB) Programme list. The other options, Nilgiri, Gulf of Mannar, and Sundarbans, are all part of the World Network of Biosphere Reserves.

Alnico is the correct answer because it is an alloy made from aluminum, nickel, and cobalt. It is commonly used for making magnets due to its high magnetic strength and resistance to demagnetization. Alnico magnets are known for their stability and ability to retain their magnetic properties even at high temperatures. This makes them suitable for various applications, including electric motors, generators, and loudspeakers. Iron ore, pure steel, and stainless steel are not used for making magnets.

The correct answer for this question is option 1 corresponds to Punan, option 2 corresponds to Kazzak, option 3 corresponds to Magyar, and option 4 corresponds to Maori.

Grapes are correctly matched with tartaric acid. Tartaric acid is a naturally occurring organic acid found in grapes, and it is responsible for the tart taste in grapes. It is commonly used in winemaking as it helps to balance the flavors and stabilize the wine. Therefore, the correct match is Grapes - tartaric acid.
