Globe , Lattitude and Longitude
Part I
Qts 1. What is a globe?
A globe is a round model of the Earth that shows its shapes, landforms and
directions as they truly relate to one another.
Qts 2. Name the heat zone in which the Equator is located?
Torrid Zone in which the Equator is located.
Qts 3. Name the latitudes between which is located the North Frigid Zone.
North Frigid Zone is located between Arctic Circle and North Pole
Qts 4. What is a grid?
Parallels of latitude and the meridians of longitude, together form a network of lines on the globe or map, called a grid.
Qts 5. How is the local time in India known as?
Ans: The local time in India is known as Indian Standard Time.
Qts 6. Define latitudes and longitudes.
1, Latitudes: The imaginary lines that circling around the Earth from east to west
are called latitudes.
2. Longitudes: The imaginary lines that run vertically from the north to the south are
called longitudes.
Qts 7. Why is it always cold at the poles?
It is always cold at the poles because they don’t get any direct sunlight
throughout the year. The Sun is always low on the poles, even in the middle of
summer.
Qts 8. How many heat or climatic zones is the Earth divided into?
Ans: The Earth is divided into three heat or climatic zones; namely Torrid Zone,
Temperate Zone and Frigid Zone
Qts 9. Why are lines of longitude called meridians of longitude
1. Longitudinal lines are drawn around the Earth from the North Pole to the South
Pole.
2. These semicircles are of equal length and are known as lines of longitude or
meridians of longitude.
Qts 10. Why are lines of longitude called meridians of latitude
1.All latitudes are drawn parallel to the Equator and run from west to east.
2. As these
are parallel to the Equator, they are called parallels of latitude.
Qts 11. Why is the world divided into time zones?
The world is divided into time zones because different part of earth gets
daylight (sunlight) at different times, so to avoid confusion in keeping time over
different parts of the country it is divided into time zones.
Qts 12. Name the various heat zones on the Earth. Write one line about each of them.
1.There are three heat zones on the Earth namely Torrid Zone, Temperate Zone
and Frigid Zone
2.Torrid Zone: This is the hottest zone because sun rays fall directly.
3.Temperate Zone: The Temperate Zone is a zone of moderate temperature.
4. Frigid Zone: The Frigid Zone is a very cold zone because this zone hardly receive any
sun rays.
Qts 13. What is a time zone? Give an example.
1.A time zone is an area that observes a uniform standard time for legal,
commercial and social purposes.
2. Time zones tend to follow the boundaries between
countries and their subdivisions instead of strictly following longitude, because it is
convenient for areas in frequent communication to keep the same time.
3.Example
GMT (Greenwich Mean Time) and IST (Indian Standard Time).
14. What is IST?
Indian Standard Time (IST) is the time zone observed throughout India, with a
time offset of UTC + 05:30. India does not observe daylight saving time or other
seasonal adjustments.
15. What is the International Date Line? Explain how time and dates change as a
person crosses the IDL.
1. By international agreement, the 1800 meridian is called the International Date
Line and it is 1800 both east and west.
2. When a person crosses IDL or move from the
left (Eastern Hemisphere) to the right (Western Hemisphere), he goes back by a day,
or gain a day therefore, there is a change in time and dates.

Ans the Southern Hemisphere.
