2.2 Exercise Questions with Answers:
Answer the following questions briefly.
Q. What is the true shape of the earth?
A. The true shape of the earth is a sphere flattened at the poles. Such a shape is called a geoid.
Q. What is the latitudinal value of the Tropic of Cancer?
A. The three heat zones of the earth are the torrid zone, temperate zone, and frigid zone.
Q. What are parallels of latitude and meridians of longitude?
A. Parallels of latitudes. All of the imaginary circles parallel to the Equator are called parallels of latitudes. These circles have varying centres and all these central points lie on the same line: the axis of the earth. Meridians of longitudes. All of the imaginary circles perpendicular to the Equator are called meridians of longitudes. These circles have the same centre, which is also the centre of the earth.
Q. Why does the torrid zone receive the maximum amount of heat?
A. The torrid zone is the area that receives the maximum heat of the sun because the mid-day sun is exactly overhead at least once a year on all latitudes in between the Tropic of Cancer and the Tropic of Capricorn.
Q. Why is it 5.30 p.m. in India and 12.00 noon in Ixmdon.
A. India and the United Kingdom lie on different longitudes. Each degree of longitude corresponds to a difference of four minutes. This is because the earth rotates 360° in 24 hours, 1° in 4 minutes. The standard meridian of India is 82° 30′ E, and that of London is 0°. This means a difference of 4 minutes x 82.5 = 330 minutes = 5.5 hours. So when it is 12 noon in London, it is 5.30 p.m. in India.
