The Earth and the Graticule |
(A)
(1) What term is used for the imaginary east – west horizontal lines on the earth?
Ans:- Parallels
(2) What is the shape of the meridians?
Ans:- Circular
(3) What do the parallels of latitude and meridians of longitude together form of the globe?
Ans:- Graticule
(4) How many parallels are there in the northern hemisphere?
Ans:- 89
(5) Which circle forms the eastern and western hemispheres?
Ans:- 00 prime meridian and 1800 meridian
(6) Which circle appears as a point on the globe?
Ans:- North/South pole
(7) How many places on the earth may be located on 450N parallel?
Ans:- Many
(B)
(1) Parallels of latitude lie parallel to the prime meridian.
Ans:- True
(2) All parallels of latitude converge at the equator.
Ans:- False
(3) Parallels and meridians are imaginary lines.
Ans:- True
(4) 80 4’ 65” is a north meridians.
Ans:- True
(5) Meridians are parallel to each other.
Ans:- False
(D)
(2) How much is the angular distance between the tropic of cancer and tropic of Capricorn?
Ans:- The angular distance is – 46.8738 degrees.
(4) Write down the main uses of Graticule?
Ans:- The parallels and meridians on the globe from a net that is called a graticule.
- This facilitates determining the location of a place.
- Thus we use graticule for determining the locations on the earth.
- This method is used in Geographical-Information system (GIS) and global positioning-system (GPS).
Wikimapia and bhuvan of ISRO on the internet also make use of graticulis.
(E) Complete the following table:
Characteristics |
Parallels of latitude |
Meridians of longitude |
Shape |
Circular | Semi-circular |
Size | Size of each parallel is different. |
Meridians are half of a great circle on Earth’s surface. |
Distance |
The distance between two parallels remain constant (111km) run parallel to each other. |
Distance between two meridians is larger on the equator and the same decreases towards the poles. |
More Extra Questions
Multiple choice questions: (marks:1)
1.) Which is considered as the largest parallel?
Ans: The Equator is called the largest parallel.
2.) What bisects the Earth into two hemispheres?
Ans: The Equator bisects the Earth into two hemispheres.
3.) How many parallels are present in each hemisphere?
Ans: There are 90 parallels present in each hemisphere.
4.) What are meridians?
Ans: Meridians are imaginary semicircular lines that join the both poles.
5.) What is graticule?
Ans: The parallels and meridians on the globe form a net that is graticule.
6.) What is the full form of GIS?
Ans: Geographical Information System.
7.) What is the full form of GPS?
Ans: Global Positioning System.
8.) Write down the full form of ISRO?
Ans: Indian Space Research Organisation.
9.) Write down the full form of IRNSS?
Ans: Indian Regional Navigation Satellite System.
10.) Why is the equator considered as 0° parallel?
Ans: The degree of parallel is measured from the equator. That’s why the equator is considered as 0° parallel.
11.) What is latitude?
Ans: The latitude is the angular distance of a place from the equator. This distance is measured at the centre of the earth on either side of the equator.
Answer the following questions: (marks:2/3)
1.) What is the globe? What are the uses of the globe?
Ans: The Earth’s surface contains oceanic waters, uneven nature of the land,forests, innumerable islands of different sizes and buildings. Thus it is impossible to draw lines on the Earth. In order to overcome this difficulties,geographers developed a miniature model of the Earth in the form of a globe.
Uses or benefits:
- Globe can use to determine locations on the Earth.
- One can actually draw horizontal and vertical lines on a globe though not on the Earth.
2.) What is the North pole and South pole?
Ans: The Equator divides the Earth into north and south parts. The one to the North is called the northern hemisphere and the other one to the south is known as the southern hemisphere. Towards the North and South of the equator, parallels of latitude progressively become smaller and smaller on the globe and also on the Earth, at the North and the South ends of the Earth’s axis they appear as points . These are called the north pole and South pole.
3.) What do you know about prime meridians?
Ans: prime meridians are considered to be 0° longitude.0° and 180° meridians lie opposite sides on the globe forming a circle and this circle divides the Earth into two equal parts – The Eastern hemisphere and the Western hemisphere. All meridians are equal in size. We can draw 360 meridians at a distance of 1°.
- 0° Prime Meridian
- 180° meridian
- 1°East to 179°East meridians. Thus, we have 179 meridians in the eastern hemisphere.
- 1° West to 179° West meridians. Thus, 179 meridians in the western hemisphere. The prime meridian passes through Greenwich city that’s why it is also known as Greenwich meridian.
4.) What is GIS?
Ans: Geographical Information System or GIS is the database of geographical information created through statistical methods. This can be used for discovering new characteristics of the planet earth. This has been mainly used in remote sensing technologies.
5.) What do you know about GPS?
Ans: Global Positioning System or GPS is a technique for determining the location of any place on the earth with the help of satellites and computers. The GIS program is used in this technology.
