41. Which one of the following statements about metamorphic rocks is not correct?

Correct Answer: (d) Rocks that originally were composed of one dominant mineral are often foliated by metamorphism.
Solution:In the process of metamorphism in some rocks grains or minerals get arranged in layers or lines. Such an arrangement of minerals or grains in metamorphic rocks is called foliation or lineation.

42. Which one of the following 'discontinuities' separates the Earth's crust from the mantle?

Correct Answer: (b) Mohorovicic
Solution:The Mohorovicic discontinuity or the Moho separates the Earth's crust and the mantle.

43. Which one of the following cities of the world would represent the greatest linear velocity of rotation of the Earth?

Correct Answer: (a) Kampala, Uganda
Solution:The greatest linear velocity of rotation of Earth is near the equator. Kampala, Uganda is near the equator and hence the linear velocity of rotation of Earth is greatest at this location.

44. What will happen if you are flying east across the International Date Line?

Correct Answer: (d) You will lose 24 hours
Solution:The International Date Line is located at about 180° east or west. It is halfway around the world from the prime meridian or 0° longitude. Crossing the line from the east to the west there is gain of a day (24 hours).

45. The Prime Meridian does not pass through which one of the following African countries?

Correct Answer: (a) Morocco
Solution:The Greenwich pass through England, France, Spain, Algeria, Mali, Burkina Faso, Togo, Ghana and Antarctica. There is an international agreement that the meridian that runs through Greenwich, England, is considered as the official prime meridian.

46. Piecing together the puzzle of geologic time to create and analyze historical maps of the Earth is known as

Correct Answer: (d) paleogeography
Solution:Paleogeomorphology is the study of historical physical geography or historical landforms. It is a branch of geomorphology that is concerned with the study of ancient topographic features now either concealed beneath the surface or removed by erosion.

47. What is the nature of velocity-time graph for a car moving with uniform acceleration?

Correct Answer: (c) Straight line
Solution:The velocity time-graph graph of a body moving with uniform acceleration represents a straight line.

48. The amplitude of sound waves is measured in the units of

Correct Answer: (a) pressure
Solution:Amplitude is measured in metres; hence it is measured in the units of distance. The greater the amplitude of a wave then the more energy it is carrying.

49. A current of 0-6 A is drawn by an electric bulb for 10 minutes. Which one of the following is the amount of 1 electric charge that flows through the circuit?

Correct Answer: (c) 360 C
Solution:Current is the movement and flow of charge generally electrons. Current can be calculated using the formula formula I = Q/ t, where I represents the current, Q represents charge, and t represents time.
therefore, Q = I t = 0.6 A × 10 × 60 s = 360 C
= It = 0.6 A × 10 × 60 s = 360 C

50. A DC generator works on the principle of

Correct Answer: (c) Faraday's laws of electromagnetic induction
Solution:A DC generator is a rotating machine that supplies an electrical output with unidirectional voltage and current. It operates on the principle of Faraday's laws of electromagnetic induction. Faraday's law states that a current will be induced in a conductor which is exposed to a changing magnetic field.
