2. Define and explain the usefulness as well as importance of the following:
(a) International Date Line
(b) Globe
(C) Indian Standard Time
3. Differentiate between
(a) Northern Hemisphere and Southern Hemisphere
(b) Temperate Zone and Frigid Zone.
(c) Local Time and Standard Time
Answers
Answer:
Ans 1 . (a) It is located halfway round the world from the prime meridian—the zero degrees longitude established in Greenwich, England, in 1852. The International Date Line functions as a “ line of demarcation ” separating two consecutive calendar dates.
(b) Globes are versatile - they can be used in any grade, and are relevant in many fields of learning. A globe will allow students to learn about different countries, including the formation of bodies of water, mountain ranges, natural resources, and the effect that the climate has on different locations.
(c) Indian Standard Time is the time observed in India and Sri Lanka. It passes through Allahabad. India has a time of GMT+5:30. It's main importance is that it helps us in scheduling partys, functions, etc.
Ans 2. (a) The Northern Hemisphere refers to the half of the planet that is north of the equator, while the Southern Hemisphere is all of the planet south of the equator. Some continents run through both hemispheres, although all of Europe and North America are in the Northern Hemisphere.
(b) temperate zone lies after torrid zone where as frigid zone lies after temperate zone in temperate zone the temperature is moderate whereas in frigid zone the temperature is very cold in temperate zone the temperature is not extreme where as people are able to experience summer winter rainy season extra but people living in frigid zone only fields winter and sometimes only they are able to see sun .
(c) The local time of a particular place refers to the time determined under the basis of the sun's apparent movement. On the other hand, the standard time refers to the fixed time of several places in a given region that fall under the same standard meridian.

Answer:
A.INTER NATIONAL DATE LINE is an imaginary line is of demarcation on the surface of the earth that runs from the North pole to the South pole and demarcates the change of one calender to next. It passes through the middle of Pacific ocean roughly following the 180 degree of longitude but deviating to pass around some territories and island groups .
B.A GLOBE is a real necessity , science is the true model of the earth . It is essential in all stages of geography teaching. It emphasizes the physical unity of the world and shows one part is related to all the rest . A model globe of earth is called a terrestrial globe
C. INDIN STANDARD TIME is the time zone observed through the India . It is half hour time zone . It's local time differs from 30 minutes instead of the normal whole hour .
3.
A. Northern hemisphere: it refers to half of the planet from North to equator . Some continents run through this hemisphere like Europe and North America etc...
Southern hemisphere: it refers to half of the planet from South to equator. Some continents run across this hemisphere like India and Atlantic etc...
B.temperate zone: this zone span from either North or South of the subtropics . They occur in middle latitudes between tropics and polar region
Frigid zone: they are also called as arctic or Atlantic.It is in North pole or between the Antarctic and the South pole first known use of frigid zone
C.Standard time: it is reference to particular area . It is officially set up for country by law.prime meridian and Greenwich longitude lie in this region.
Local time: passing through the region or country.Local time is determined by Sun's position. Lmt and gmt longitude lie in this region
