Telangana SCERT Solution Class VI (6) Social Studies Chapter 2 Globe – A Model of the Earth
( 2 ) Ramesh says “ Earth is flat ‘’. What do you say?
It will be incorrect to say that Earth is flat but rather we can say that it depicts a spherical shape but it would not be relevant to say that the Earth is entirely round . As it is pressed slightly at the two poles and there is a little bulging in the middle, for this reason it would not be correct to infer that the Earth depicts a perfect sphere. The equator refers to an imaginary line around the Earth’s surface. Due to its extreme slightness , it is not shown by most of the maps and globes.
( 3 ) Rosy is spinning a bangle like a top. What shape do you see?
When Rosy will spin a bangle like a top then we will see a spherical shape . Furthermore, it will look like shape of the Earth or Globe having both latitudes and longitudes. In short, we can say that it will look exactly like a globe.
( 4 ) Collect information about explorers like Columbus.
Columbus was not only an Italian explorer but he was also a navigator who was successful in travelling four thousand miles in the Atlantic Ocean towards the direction of the west. After reaching some islands, he thought that he had reached India. Therefore, he decided to name it as West Indies. In certain course of time, this exploration contributed to the discovery of America. Then after further exploration, a continent was discovered by Amerigo Vespucci in the later period of time and this continent was known by the name of America after him.
( 6 ) “ The Sun always rises in the east’’. Find out the reason for this .
The rotation of the Earth towards the direction of the east is the sole reason which facilities all the planets including sun, moon and stars to rise from the direction of the east. These planets then paves their way towards the western direction , after rising from the eastern side. When there will be a backward rotation of the Earth, then it will be possible for the sun to rise from the west because the stars does not possess the ability to spin just like the earth. Due to this reason, the sun always rises in the east.
( 7 ) Why do we draw imaginary lines on the globe / map?
The main reason for drawing imaginary lines on the globe or map is that it facilitates in locating places on the globe or map .Owing to this reason, there are lines on maps and globes and these lines are known by the term of latitude and longitude. The planet does not have these lines in real but these are imaginary lines that enables us to locate places on the globe.
( 8 ) What is the effort put by scientists and sailors to know about earth ?
In order to know about the earth, the scientists and sailors have put tremendous effort. As for instance, they kept on advancing around the earth by risking their own lives and some had to compromise their lives for the purpose of knowing the earth.
( 9 ) Observe the following pictures and fill the boxes with the names of the shaded hemispheres.
1 ) As the shaded part is in the northern side, for this reason it is known by the term of Northern Hemisphere.
2) As the shaded part is in the western side, for this reason it is known as Western Hemisphere.
3) As the shaded part is in the southern side, for this reason it is known as Southern Hemisphere.
4) As the shaded part is in the eastern side, for this reason it is called Eastern Hemisphere.
The Northern Hemisphere is the half portion of the planet Earth that is between the North Pole and the equator.
The Southern Hemisphere is another half portion of the Earth that is between the South Pole and the equator.
The portion of the Earth that contains not only surrounding water but also North and South America is known by the term of Western Hemisphere.
The half portion of the Earth which comprises almost all of Europe, Asia, Africa and Australia is known by the term of Eastern Hemisphere.
