41. Which branch of agriculture refers to livestock raising and selective breeding?
[A] Petrology
[B] Animal Husbandry
[C] Veternary Science
[D] Mixed Agriculture
Show Answer
Correct Answer: B [Animal Husbandry]
Notes:
Animal husbandry – It is the branch of agriculture which refers to livestock raising and selective breeding.
It is the management and care of animals in which the genetic qualities and behavior of animals are further developed for profit.
42. Lake formed in a cut off river, meander is called__:
[A] Playa Lake
[B] Meteoric Lake
[C] Ox-Bow Lake
[D] Crater Lake
Show Answer
Correct Answer: C [Ox-Bow Lake]
Notes:
An oxbow lake is a U-shaped body of water formed when a wide meander from the main stem of a river is cut off to create a lake. This landform is called an oxbow lake for the distinctive curved shape, named after part of a yoke for oxen.
43. The core of the earth is also known as__?
[A] Lithosphere
[B] Mesosphere
[C] Barysphere
[D] Centrosphere
Show Answer
Correct Answer: C [Barysphere]
Notes:
The interior of the Earth beneath the lithosphere, including both the mantle and the core, is known as barysphere. However, it is sometimes used to refer only to the core or only to the mantle.
44. What are the imaginary lines encircling the earth horizontally called ?
[A] Latitudes
[B] Longitudes
[C] Isobars
[D] Isotherms
Show Answer
Correct Answer: A [Latitudes]
Notes:
Imaginary lines drawn parallel to the equator which run east to west (horizontally) on earth’s surface are called latitudes. Latitude is an angle which ranges from 0° at the Equator to 90° (North or South) at the poles. It is used together with longitude to specify the precise location of features on the surface of the Earth.
45. Marble comes under which category of rocks?
[A] Sedimentary
[B] Igneous
[C] Metamorphic
[D] None of these
Show Answer
Correct Answer: C [Metamorphic]
Notes:
Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. It is composed primarily of the mineral calcite (CaCO3) and usually contains other minerals, such as clay minerals, micas, quartz, pyrite, iron oxides, and graphite. Under the conditions of metamorphism, the calcite in the limestone recrystallizes to form a rock that is a mass of interlocking calcite crystals.
46. The amount of insolation received at a place on the surface of the earth depends upon:
[A] its climate
[B] the longitude of the place
[C] its latitude
[D] the altitude of the place
Show Answer
Correct Answer: C [its latitude]
Notes:
Insolation is a measure of solar radiation energy received on a given surface area in a given time. It mainly depends on two factors: (a) the angle at which the Sun’s rays strike the Earth, and (b) the length of time of exposure to the rays. Both of these factors are controlled by the latitude of the location and time of the year.
47. The ash–grey soils of high–latitude coniferous forests are known as_:
[A] Tundra soils
[B] Podsols
[C] Grey–Brown soils
[D] Red and Yellow soils
Show Answer
Correct Answer: B [Podsols]
Notes:
Podsols are ash-grey coloured soils that are found in high-latitude coniferous forest belt having very long cold winters, short cool summers and a moderate precipitation throughout the year. These soils are acidic, infertile and of limited value for agriculture. These are useful for dairying and mixed farming.
48. Rubber plantations are found in__?
[A] Temperate forests
[B] Mountain regions
[C] Polar regions
[D] Equatorial regions
Show Answer
Correct Answer: D [Equatorial regions]
Notes:
The rubber plant grows wild in the equatorial regions of the world which are marked by rainfall of around 250 cm evenly distributed without any marked dry season and with at least 100 rainy days per year; temperature range of about 20°C to 34°C with a monthly mean of 25°C to 28°C; and high atmospheric humidity of around 80%.The three largest producing countries, Thailand, Indonesia and Malaysia, together account for around 72% of all natural rubber production.
49. The fur of the animals living in colder regions__:
[A] protects them from water
[B] traps the air and keeps them warm
[C] protects them from enemies
[D] makes them appear beautiful
Show Answer
Correct Answer: B [traps the air and keeps them warm]
Notes:
The fur of the animals living in colder regions traps the air and keeps them warm.
50. Which among the following is not an example of terrestrial habitat?
[A] Forest
[B] Grasslands
[C] Deserts
[D] Swamps
Show Answer
Correct Answer: D [Swamps]
Notes:
Terrestrial habitats are ones that are found on land, like forests, grasslands, deserts, shorelines, and wetlands. Terrestrial habitats also include man made habitats, like farms, towns, and cities, and habitats that are under the earth, like caves and mines. A swamp is an area of land that is always saturated with water and has various trees and plants growing throughout.
