Answer 1

Answers:

(a) The true shape of the earth is a sphere flattened at the poles. Such a shape is called a geoid.

(b) A globe is an exact miniature model of the earth. It shows the earth in its actual shape, with all continents, oceans, etc marked at their proper places.

(c ) The latitudinal value of the Tropic of Cancer is 23 1/2° N.

(d) The heat zones of the Earth are: the Torrid Zone, the Temperate Zones and the Frigid Zones.

(e) 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.

(f) The mid-day sun directly faces the area between the Tropics of Cancer and Capricorn. So the heat received is maximum at these latitudes. These latitudes fall under the Torrid Zone.

(g) India and the United Kingdom lie on different longitudes. Each degree of longitudes 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.

Answer 2

Answer:

1. A globe is a small model of earth.

2 . with the same distance between them for all their length

3. line that we imagine on the surface of the earth that joins the North Pole to the South Pole and passes through a particular place

4. complete network of parallel of latitude and meridian of longitude drawn on the map or globe is called Earth's Grid.

5. the time based on the meridian through a specific place, as a city, in contrast to that of the time zone within which the place is located; the time in a specific place as compared to that of another place to the east or west.

6. Local time is the time of a country
