The ‘Climate’ is the average atmospheric conditions of an area over a considerable period of time. For proper conclusions, observations are needed for a minimum period of :
(a) 5 years
(b) 10 years
(c) 31 years
(d) 35 years
(c) 31 years
Explanation:
Climate is determined based on long-term patterns of temperature, precipitation, and other atmospheric conditions. According to the World Meteorological Organization (WMO), at least 31 years of data are required to establish reliable climatic averages and draw conclusions about an area's climate.
Perspiration is maximum when temperature is :
(a) low and air is dry
(b) low and air is humid
(c) high and air is dry
(d) high and air is humid
(d) high and air is humid
Explanation:
When the temperature is high and the air is humid, the body's ability to cool down through perspiration is reduced because humid air slows the evaporation of sweat. To compensate, the body increases sweat production, making perspiration more noticeable under these conditions.
Match the following :
| A. | Selvas | 1. | Rainy tropical forests | |
| B. | Pampas | 2. | Equatorial rain forests | |
| C. | Savanna | 3. | Temperate grassland | |
| D. | Llanos | 4. | Wet and dry tropical forests |

Correct Answer: (c) 2, 3, 1, 4
Explanation:
Consider the following statements associated with Mediterranean climate :
1. It is so named because it occurs extensively in the periphery of Mediterranean sea.
2. These lands are exposed to hot, dry, land winds during the summer months.
3. The seasonal range of temperatures is considerable less than that in other areas of corresponding latitudes.
Which of these statements are correct ?
(a) 1, 2 and 3
(b) 1 and 2
(c) 2 and 3
(d) 1 and 3
(a) 1, 2, and 3
Explanation:
Nights are cooler in the deserts than in the plains because :
(a) sand radiates heat more quickly than the earth
(b) the sky remains clear most of the time
(c) sand absorbs heat more quickly than the earth
(d) none of the above
(a) sand radiates heat more quickly than the earth
Explanation:
Sand in deserts absorbs heat quickly during the day and radiates it back into the atmosphere just as quickly at night, causing significant drops in temperature. In contrast, plains retain heat longer due to soil and vegetation cover, resulting in warmer nights.
Which one of the following pairs is correctly matched ?
(a) Monsoon Region : Campos
(b) Mediterranean Region : Llanos
(c) Pampas Region : Prairies
(d) Savanna Region : Steppes
(c) Pampas Region: Prairies
Explanation:
The Pampas Region in South America is known for its extensive grasslands, which are similar to the Prairies of North America. The other options are incorrectly matched:
A large number of species are found within a small unit of area of :
(a) mangrove coastal forests
(b) coniferous temperate forests
(c) deciduous monsoon forests
(d) wet evergreen equatorial forests
(d) wet evergreen equatorial forests
Explanation:
Wet evergreen equatorial forests, such as the Amazon rainforest, have the highest biodiversity. Their warm, humid conditions and year-round rainfall support a wide variety of plant and animal species in a relatively small area.
Summers in Western Europe are warmer than those in Eastern Europe because of :
(a) the influence of the warm ocean current
(b) the influence of bright sunshine
(c) the lower mountains terrain
(d) peninsular nature of the continent
(a) the influence of the warm ocean current
Explanation:
The North Atlantic Drift, a warm ocean current, moderates the climate of Western Europe, keeping summers warmer and winters milder. Eastern Europe, farther from the ocean, experiences more extreme temperatures due to its continental climate.
Consider the following statements :
1. In equatorial regions, the year is divided into four main seasons.
2. In mediterranean region, summer receives more rain.
3. In China type climate,rainfall occurs throughout the year.
4. Tropical highlands exhibit vertical zonation of different climates.
Which of these statements are correct ?
(a) 1, 2, 3 and 4
(b) 1, 2, and 3
(c) 1, 2, and 4
(d) 3 and 4
(d) 3 and 4
Explanation:
Consider the following ecosystems :
1. Taiga
2. Tropical evergreen
3. Tropical deciduous
4. Tundra
The correct sequence in decreasing order of the albedo values of these ecosystem is :
(a) 1, 4, 3, 2
(b) 4, 1, 2, 3
(c) 4, 1, 3, 2
(d) 1, 4, 2, 3
(c) 4, 1, 3, 2
Explanation:
Albedo refers to the reflectivity of a surface. Higher albedo means higher reflectivity and less heat absorption.
