Ans:- There are two kinds of poles on earth
1-North pole
2-South pole
4:- What is north pole?
Ans:- The point in the Northern Hemisphere where the Earth's axis of rotation meets its surface. This point is called north pole. It is also known as North geographical pole.
5:- What is south pole?
Ans:- The point in the Southern Hemisphere where the Earth's axis of rotation meets its surface. This point is called south pole. It is also known as South geographical pole.
6:- How many types of imaginary lines drawn on earth?
Ans:- There are two types of imaginary lines on Earth.
1-longitudes
2-latitudes
7:- What are latitudes?
Ans:- The circular lines running from east to west on a globe are called latitudes . Latitudes are also called parallels.
8:- What is equator?
Ans:- The line of latitude which runs across the middle of the globe, dividing the globe into two equal halvs is called an equator.
9:- Who is the longest parallel on the globe?
Ans:- equator
10:- What is Northern hemisphere?
Ans:- The part of the earth that is located north of the equator is called Northern Hemisphere.
11:- What is Southern Hemisphere?
Ans:- The part of the earth that is located South of the equator is called Southern Hemisphere.
12:-Write some characteristics about parallels.
Ans:- The some characteristics about parallels are
1- All the parallels are drawn at the equal distance from each other.
2-No latitude or parallel cuts each other
3-The length of latitudes decreases as they move away from the equator .
4-Almost all the parallels are complete circles.
5-The North pole and South pole are just point.
6-No parallel meets the other.
7-Latitudes are measured with the unit degree
8-We mark the equator as zero degree latitude.
9-We write 90 degree N for North pole and 90 degree S for south pole.
10- Parallels are drawn at the interval of 1 degree.
11-There are 90 parallels in the northern hemisphere and 90 parallels in southern hemisphere
12:- There are 181 parallels in all including the equator.
Ans:- Our earth is round in shape. It is little flat at the top and bottom and bulges from the center. Hence it looks like an orange.

12:- There are 181 parallels in all including the equator.
13:- What is tropic of cancer?
Ans:- The parallel that lies on 23.5°N is called tropic cancer.
14:- What is tropic of Capricorn?
Ans:- The parallel that lies on 23.5°S is called tropic of Capricorn.
15:- What is Arctic circle?
Ans:- The parallel that lies on 66.5°N is called Arctic circle.
16:- What is Antarctic circle?
Ans:- The parallel that lies on 66.5°S is called Antarctic circle.
17:- What are longitudes or meridians?
Ans:- The semi-circular lines that running from north pole to south pole on the globe are known as longitudes or meridians.
18:- Write some characteristics of longitudes or meridians.
Ans:- 1-All longitudes have the same length.
2-The longitudes cut the latitudes at right angle.
3- The distance between two longitudes or meridians is maximum at the equator.
4-The distance between successive longitudes decreases as they move towards the pole.
5-Meridians help to measure the distance in the east-west direction.
19:- What is prime meridian?
Ans:- The longitude that passed through Greenwich near London and is marked as 0° longitude is called prime meridian. The prime meridian is also known as Greenwich meridian.
20:- What is eastern hemisphere?
Ans:- The part of the earth that lies east of the prime meridian is known as eastern hemisphere.
21:- What is the Western hemisphere?
Ans:- The part of the earth that lies west of the prime meridian is known as western hemisphere.
22:- How many meridians present on a globe? Explain it.
Ans:- There are 180 meridians towards east and 180 meridians towards the west. So there are 360 Meridian on the globe.
23:- Write short notes about International date line.
Ans:- The 180° meridian is called the International date line. It passes through the middle of the plastic ocean. All the passes located west of the International date line one calendar day ahead of all the places located east of the International date line.
24:- What is greed?
Ans:- Latitudes and longitudes intersect each other and from a network. This network is called a grid. The grid help us to locate different places on the globe.
25:- Why does Sun always rise in east?
Ans:- The sun always rises in east because earth rotate the west towards the east.
26:- In which countries the Sun rises First?
Ans:- All the countries that located. East of the prime meridian face the the sun first.
For example - The easternmost country, faces the sun first.
USA is located in the western. Hemisphere, faces the sun in end.
27:- What is the meaning of Greenwich mean time and what is its use?
And:- The time of the meridian of Greenwich is observed as the mean time, so the name Greenwich mean time or GMT is given. GMT is used as the basis of standard time throughout the world. Based on it, the local time of any country can be calculated.
28:- What do you know about Indian standard time?
Ans:- Meridian that passes through its centre, and the time at that meridian is considered as the standard time of that country. In India, 88.5°E, the meridian of Allahabad, is taken for calculating the standard time and is known as the Indian standard time or IST. The IST is 5.5 hours ahead of the GMT.
