Question 1.Do you think there is any correlation between the crops grown in your region and the seasons? Find out by discussing with your eiders and friends and write a short essay on it?

Answer: Ours is a small village Anther vedipalem in East Godavari district. In our area, we have 3 crop seasons - Kharif, Rabi, and Zaid. The farmers cultivate paddy and maize in the Kharif season. This season is up to October and November. Rabi is cultivated as winter crop. In Rabi also some cultivate paddy and some cereals. Duration of this season is upto March and April. After that some fruits and vegetables are grown in the Zaid season. In addition to these we have coconut plantations which give fruits throughout the year. Due to these reasons there is correlation between crops and seasons

Question 2.Why do you think Andhra Pradesh does not receive any snowfall during winter months?

Answer: Snow forms in the clouds that are below freezing. Andhra Pradesh is in tropical belt. To get snow the temperatures in Andhra Pradesh are not enough cold. So Andhra Pradesh does not receive any snowfall during winter season

Question 3.We have a rainy season. How do you think it is related to the movement of the Earth and the pattern of Suns rays? Does it occur in the summer or winter or in the season in between?

Answer: The seasons occur due to the revolution and the pattern of Suns rays. During summer the Suns rays fall straightly on our area. Then the air in the atmosphere gets heated and moves up by forming low pressure belt. The winds from high pressure belt from the Indian ocean blow to this area and give rains. We receive rains after summer and in the beginning of winter due to these seasonal winds-monsoons

Question 4.Collect information about time of Sunrise and Sunset for different months of the year in your place (you can look up the local newspaper for this). Calculate the duration of day and night- how many hours every day - for every month. Do you see any pattern in this?

Answer: I have opted Kanyakumari in Tamilnadu for this project. It is famous for its sunrise and sunset

Date/Month Sunrise Sunset Day time Duration Night time Duration
1/1/2015 06-33 18-13 11-40 12-20
1/2/2015 06-40 18-27 11-47 12-13
1/3/2015 06-33 18-31 11-58 12-02
1/4/2015 06-18 18-29 12-11 11-49
1/5/2015 06-05 18-29 12-24 11-36
1/6/2015 06-01 18-34 12-33 11-27
1/7/2015 06-06 18-41 12-35 11-25
1/8/2015 06-12 18-40 12-28 11-32
1/9/2015 06-12 18-28 12-16 11-44

1/11/2015 06-08 17-58 11-50 12-10
1/12/2015 06-18 18-00 11-42 12-18

After thorough observation I came to the following conclusion. * The duration of night time is more in the months from August to January. The duration of day time is more in the months from February to July

Question 5.Explain the idea of rotation of the Earth to your parents or sisters or brothers. Write down their questions or doubts and try to answer them?

Answer: I explained the earths rotation to my brother and sister. I write down their doubts here under

  • Why does the earth rotate
  • What is the speed of the earths rotation
  • How can we prove the earths rotation
  • Why is the axis of earth tilled
  • What happens if earth stops its rotation
Question 6.Imagine that the Earth does not rotate but goes around the Sun around the year. What difference will it make to the seasons and distribution of temperature?

Answer: The one portion of the earth which is infront of the sun would constantly get Suns heat and light and the other portion would remain cold and dark. This would make both portions unfit for life-the bright half would be too hot and the dark half would be too cold. This would happen if the earth did not rotate on its own axis

Question 7.Identify a country in the Temperate Belt in both Northern and Southern Hemisphere. Compare the seasons in those countries and your place. Which will be warmer in May- June and which will be cooler in December - January or in March or September Identify a country in the Temperate Belt in both Northern and Southern Hemisphere?
(OR) Compare the seasons in those countries and your place.

Answer: I have opted Russia in Northern hemisphere, Falkland Islands for this. Moscow in Russia - It is located near 55.7558° N. latitude. The average temperatures are as follows

Falkland Islands: It is extended from 51 °S latitude to 52°S. Latitude. The seasons are quite opposite in both hemispheres. Ours is Vijayawada in Andhra Pradesh. This is located at 16°5200 N. latitudes. Here April and May are famous for high temperatures. Winter season will be in December and January. When compared to Russia and Falkland Islands, the summer temperatures and winter temperatures are both higher than their summer temperatures. But the seasons in these three areas are more or less equal.
Question 8.What are the six seasons of Indian climate?

  • Vasantham - Mid March - Mid May
  • Greeshrnam - Mid May to Mid July

Question 9.Read the first paragraph of this chapter and answer the following question?

Human beings live along with a large community of plants and animals. We can observe constant change in the course of the year - the flowering and fruiting of trees and plants changes in the animal activity in our surroundings. As months pass by you would have noticed that trees shed leaves, stand bare, new shoots come forth, they flower and fruit. You may have also noticed that in different times of the year you get different kinds of vegetables and fruits. In some months it is very hot and in some it is cold or wet

"What is the impact of seasons on the lives of human beings ?"
