AP 5th Class EVS Lesson 11 Earth to Space Best Notes

  1. Conceptual Understanding:

Question 1.
Write the differences between Latitudes and Longitudes?
Answer:

Latitudes Longitudes
1. Circles run from east to west on the globe are called ‘Parallels’ or’ Latitudes’. 1. Imaginary lines running from North to South are called ’meridians’ or ’Longitudes’.
2. The latitude that divides the globe into two equal parts is the ’Equator’. 2. The longitude that divides globe into two equal parts is the prime meridian.
3. The length of Parallels decreases as we move away from the equator to the Poles. At poles these are points. 3. Distance between meridians decreases as we move away from the equator to poles.
4. There are 181 parallels. 4. There are 360 meridians.

Question 2.
Write about the globe?
Answer:
A globe is a simple and accurate model of the earth. It shows the distribu tion of land and water on the surface of the earth, we can also see the correct shape, size and location of the continents and oceans on a globe.

Question 3.
What is the shape of the earth?
Answer:
In ancient, times people believed that the earth was flat and has steep edges. Ferdinand Magellan, a Portuguese explorer, sailed around the world and proved that the earth is round. Pictures taken from space have also proved that the earth is like a sphere.

Question 4.
If the earth stops its rotation what will happen?
Answer;

  1. Day and nights may not be formed
  2. All the bodies like rocks, topsoil, trees, buildings etc,, would be swept away into the atmosphere.

III. Experiments and field observations:

Question 5.
Make a model of the solar system using balls of different sizes to represent the planets?
Answer:
Students Activity.

  1. Information Skills & Project Work:

Question 6.
Collect the information about artificial satellites sent by India and their purposes. Write a brief note.
Answer:

  1. An artificial satellite is an object that people have made and launched into orbit using rockets. Aryabhatta was the India’s first satellite lanunched in 1975.
  2. Chandrayaan-2 is an artificial satellite launched by GSLV-MKIII-M1 from Satish Dhavan space centre in Sriharikota on 22nd July 2019. It is India’s 2nd mission on the moon followed after Chandrayan-1. It comprises of an orbiter, lander and rover.
  3. Artificial Satellites provide services in the areas of communications, broad casting metrology, oceanography and resources survey. Now-a-days we are using internet, mobile phone and online sendees because of these artificial satellites.

  1. Drawing Pictures and Model Making:

Question 7.
Draw Latitudes and Longitudes on the surface of a ball.
Answer:
Students activity.

  1. Appreciation, values, application to dialy life biodiversity:

Question 8.
Why is the earth, the only planet which is only habitat by human beings?
Answer:
Earth is the only planet in our solar system that has a large water i.e 74% of the surface and living conditions for human beings. Earth is called a blue planet because of its water. Since it is having water and living conditions it is only habitat by human beings.
