Option “2” is correct. Tundra is a type of biome where the tree growth is hindered by low temperatures and short growing seasons. In tundra, the vegetation is composed of dwarf shrubs,sedges and grasses, mosses, and lichens.
104. Which of the following has maximum diurnal temperature difference?
1. Desert
2. Mountains
3. Plateau
4. Ocean
Option “1” is correct. The diurnal temperature range (DTR) is the difference between the daily maximum and minimum temperature. Desert areas typically have the greatest diurnal temperature variations.
105. Which of the following state receives rainfall due to western disturbances?
1. Punjab
2. West Bengal
3. Kerala
4. Gujarat
Option “1” is correct. Western disturbance refers to a system of low pressure that moves from west to east, bringing moisture from Eurasian water bodies, and is responsible for winter rain in northwestern India and snowfall in the Himalayan tracts. It usually brings rain during the winters but also during the pre-monsoon period. Punjab receives rainfall due to western disturbances.
106. Why does Western Ghats and Eastern Ghats both receive sufficient rainfall but Deccan Plateau receives scanty rainfall?
1. It is a rain shadow area
2. It is located parallel to wind direction
3. It is away from the coast
4. Rain bearing clouds are absent
Option “1” is correct. A rain shadow is a dry area on the leeward side of a mountainous area (away from the wind). Deccan Plateau falls in a rain shadow area thus it receives scanty rainfall.
107. Which of the following is NOT a primary green house gas in the earth’s atmosphere?
1. Methane
2. Ozone
3. Nitrous oxide
4. Hydrogen
Option “4” is correct. A greenhouse gas (GHG) is a gas in an atmosphere that absorbs and emits radiation within the thermal infrared range. This process is the fundamental cause of the greenhouse effect. The primary greenhouse gases in Earth’s atmosphere are water vapor, carbon dioxide, methane, nitrous oxide, and ozone.
108. The World’s largest island is –
1. Greenland
2. Iceland
3. New Guinea
4. Madagascar
Option “1” is correct. Greenland is the worlds largest island with an total area of 836,109 sq mi ( 2,166,086 sq km).
