Q

Artic circle

A

66 1/2° north, it is important because the area within the circle receives oblique rays of the sun, six months of day and six months of night

Q

Name the importance of latitudes

A
  1. Life only exist and is possible because of various phenomena, closely related to climate
    and vegetarian.
  2. Latitudes along with longitudes enable us for the whereabouts of the various places on the earth surface.
  3. Equator, the 0° latitude passes through the exact central and divides it into 2/2.

Q

Climatic zones of the Earth, how is it important?

A

Let it help us divide the whole into climatic zones. The world‘s climatic determine on the basis of three template zones as the amount of heat received from the sun varies because of the inclination of the earth and its spherical shape.

17
Q

Name the main heat zone

A
  1. Torrid zones.- live between Tropic of Cancer and Tropic of Capricorn. Areas between 5° north to 5° South of the equator are called doldrums or equatorial zones and are areas of low pressure because the receive direct rate of the sun.
  2. Temperate zone- between between tour zone and Arctic circle and Antarctic circle.. temperature temperature is neither hot or cold. receives slant rays of the sun during summer days in northern hemisphere are longer, but in winter, their shorter.
  3. Rigid zones.-Artic, circle to North pole and Antarctic circle to South pole.. very slant races during winter. These regions have months of winter during one year and remain frozen.
18
Q

What is longitude?

A

The long of a place is the angular distance of that place, east or west of the prime meridian

19
Q

Why longitude is called Meridian?

A

Because it means midday as all the places on the Meridian, have they noonat the same time

20
Q

How many longitudes are there?

A

360

21
Q

What is the importance of longitudes?

A

To fix the location of certain place on the earth surface
The great circle roots
Divide the earth into western and eastern hemisphere

22
Q

What are the great circle routes

A

1.The shortest distance between two points on the earth surface is the arc of great circle

23
Q

Importance of great circle roots.

A

The shortest distance between two plains, hence they used many to save fuel and time as it is very economical
2. See on the sea, also use it whenever it is possible and as long as it does not lead them into unsafe waters

24
Q

How to solve the problem of different times around the world

A

Take green, which meantime as reference for international time

25
Q

What does green, which mean time mean?

A
  1. The 0° Meridian passes through the Royal astronomical Observatory at Greenwich near London.
  2. In 1884 is decided by international agreement, adopt the local time of prime meridian.
  3. When is directly overhead at 30° longitude and it is 12 o’clock that the international time is calculated east or west of the prime meridian
  4. the rotates west to east so when it is noon at the primary radium, it will be evening to the places east and morning for the places west
26
Q

1° Meriden is equal to

A

Four minutes

27
Q

How can the local time of a place be calculated?

A

With the help of the longitude of the place

28
Q

What is standard Time?

A

A uniform time for places in approximately the same longitude established in a country or reaching by law or custom.
Generally, the standard Meridian of a country is taken as multiple of 15° or 7 1/2
India central Meridian 82 1/2° east passes through our Allahabad

29
Q

What is international dateline?

A

The international date line is a line concerned with the dates of the calendar and adopt internationally
When we travel east of this line, it is referred to as 180° east, and when we travel west of the line is referred to us, 180° west
On the other side of the line, a difference of whole day observed

30
Q

Why is the meridian one 80°° chosen as international dateline

A

Because it passes through the middle of the Pacific Ocean and there is practically no landmarks, and wherever there is landmark, a deviation has been taken

31
Q

How many time zones are there in the world?

A

24

32
Q

How many time zones do Canada, Russia, and USA have?

A

Canada has six Russia has 11 and USA has six

33
Q

What are longitude used for?

A

Locating places on the globe
Determining the local time of the place.
