Explained Answers
Q1 – B) Mount Kilimanjaro. Kilimanjaro in Tanzania is the highest mountain in Africa. Mount Kenya is second in Africa.
Q2 – C) Volga. The Volga is the longest river in Europe. The Danube is the second longest, the Rhine is shorter, the Seine flows through Paris.
Q3 – C) Mariana Trench. The Mariana Trench in the Pacific is the deepest oceanic trench in the world.
Q4 – C) Sicily. Sicily is the largest island in the Mediterranean Sea. Sardinia is second, Cyprus and Crete are smaller.
Q5 – C) Methane. Methane is a greenhouse gas. Nitrogen and oxygen make up most of the atmosphere but are not greenhouse gases in this sense, and argon is inert.
Q6 – B) El Nino. El Nino is the warming of the central and eastern Pacific that disrupts weather patterns. La Nina is the cooling phase.
Q7 – B) The Sun. Solar energy drives evaporation, and therefore the water cycle.
Q8 – A) Mangrove forests. Mangroves protect coasts by slowing waves and holding soil. Deserts, grasslands and tundra do not play this coastal role.
Q9 – C) Brazil. Brazil holds the largest share of the Amazon rainforest, with Peru and Colombia holding smaller shares.
Q10 – C) Antarctic desert. Counting cold deserts, the Antarctic desert is the largest desert in the world. The Sahara is the largest hot desert.
Q11 – B) Thames. The Thames flows through London. The Seine flows through Paris, the Danube through Central Europe, the Rhine through Germany and the Netherlands.
Q12 – B) Tugela Falls. Tugela Falls in South Africa is the highest waterfall in Africa and among the highest in the world. Victoria Falls is wider and more famous, but lower.
Q13 – C) Indian Ocean. The Indian Ocean lies between Africa to the west and Australia to the east.
Q14 – B) Natural gas. Natural gas is a fossil fuel and non-renewable. Geothermal, tidal and biomass energy are renewable in the usual classification.
Q15 – C) Troposphere. Most weather occurs in the troposphere, the lowest layer of the atmosphere.
Q16 – B) Rain gauge. A rain gauge measures rainfall. A barometer measures pressure, an anemometer measures wind speed, a hygrometer measures humidity.
Q17 – C) Anemometer. An anemometer measures wind speed. A barometer measures pressure, a thermometer measures temperature, an altimeter measures altitude.
Q18 – B) Great Barrier Reef. The Great Barrier Reef off Australia is the largest coral reef system in the world.
Q19 – B) Biodiversity. Biodiversity is the variety of plant and animal life in an area. An ecosystem is the interacting community and environment, a habitat is where an organism lives.
Q20 – B) Reusing glass bottles. Reusing glass bottles reduces waste. Burning plastic, dumping waste in rivers and burying metal do not reduce waste in the same way.
