Very Short Questions
1) What is rotation?
Ans. Rotation is the movement of the earth on its axis.
2) What is revolution?
Ans. The movement of the earth around the sun in a fixed path or orbit is called Revolution.

Ans. The plane formed by the orbit I known as the orbital plane. The axis of the earth which is an imaginary line, makes an angle of 66 ½ degree its orbital plane.
4) What causes day and light?
Ans. The days and night on the earth are caused by the rotation of the earth on its axis.
5) How are days and nights caused?
Ans. Due to the spherical shape of the earth, only half of its gets light from the sun at a time. The portion facing the sun experiences day while the other half experiences night.
6) What is the circle of illumination?
Ans. The circle that divides the day from the night is called the circle of illumination.
7) What is earthday?
Ans. The period of rotation that the earth takes to complete one rotation around its axis is called earthday.
8) What would happen if only one part of the earth got sunlight at all times?
Ans. The portion of the earth facing the sun would always experience day, thus bringing warmth to the region.
9) What would happen to the portion of the earth that faces away from the sun?
Ans. The portion that faces away from the sun would remain in darkness and be freezing cold all the time.
10) How long does it take the earth to complete one revolution?
Ans. The earth takes about 365 ¼ days to revolve around the sun.
11) Who stated that the earth is round and rotates on its own axis?
Ans. The ancient Indian astronomer Aryabhata had stated that the earth is round and rotates on its own axis.
12) What is a leap year?
Ans. A leap year is a year which has 266 days rather than 365 days. It comes after every 4 years.
13) Which month has an additional day during the leap year?
Ans. The month of February consist of 29 days during a leap year.
14) What is the shape of the earth’s orbit?
Ans. The earth revolves around the sun in an elliptical orbit.
15) Name the four seasons.
Ans. The four seasons are, summer, winter, autumn and spring.
16) Why do seasons occur?
Ans. Seasons take place due to the movement of the earth around the sun which is called revolution.
17) When does the northern Hemisphere experience summers?
Ans. When the sun shines directly on the Tropic of Cancer, the northern hemisphere receives direct heat, therefore it is summers in this region.
18) Why does the north pole experience continuous daylight for 6 months?
Ans. The North Pole is inclined towards the sun and the places beyond the Arctic circle experience continuous daylight for about six months.
19) When does the northern part of the equator experience the longest day?
Ans. On the 21st June, the northern hemisphere experiences the longest day and the longest night.
20) When does the southern hemisphere experience summers?
Ans. The Tropic of Capricorn on 22nd December receives direct rays of the sun as the South Pole tilts towards it. Therefore, the southern hemisphere experiences summers during this time.
Short answer type questions-
1.) What is the relative significance of the Earth’s revolution?
Answer-
The seasons are caused by the earth’s rotation. We have changing seasons because the earth’s location around the sun changes.
2.) How does the rotation of the Earth account for day and night?
Answer-
The Earth spins on its axis from West to East in a 24-hour period. When the Earth rotates, the half that faces the sun creates day, while the other half remains in darkness and creates night. As a result of the rotation, day and night are a continuous phenomenon.
3.) What does winter solstice mean ?
Answer-
Winter Solstice refers to the location of the earth when it is winter in the Northern Hemisphere and summer in the Southern Hemisphere.
4.) What does summer solstice mean ?
Answer-
At these locations, the longest day and shortest night occur. All of these conditions are currently inverted in the Southern Hemisphere. There, it is winter. The night outnumbers the days. The Summer Solstice refers to the Earth’s position at this time of year.
5.) How does a leap year come about?
Answer-
In reality, the Earth revolves around the Sun in 365 1/2 days. It equates to an extra 6 hours per year, which equates to 1 day every 4 years. Every four years, one day is added to the month of February. As a result, every fourth year, February has 29 days rather than 28. A year with 366 days is referred to as a leap year.
6.) What exactly are axis and orbit?
Answer-
Axis:
The axis of the Earth is an imaginary line joining the North pole with the South pole. It makes an angle of 6614° with its orbital plane.
Orbit:
Orbit is the elliptical path on which heavenly bodies move around their sun or planet.
Long answer questions
1) Write a short note on the circle of illumination.
Ans. The plane formed by the orbit is called the orbital plane. The earth receives light from the sun. due to the spherical shape of the earth, only half of it gets light from the sun at a time. The portion facing the sun experiences day while other half away from the sun experiences night. The circle that divides the day from night on the globe is called the circle of illumination. This circle does not coincide with the axis.
2) Explain the two motions of the earth.
Ans. The earth both rotates and revolves on its axis and around the sun. Rotation is the movement of the earth on its own axis. The axis of the earth which is an imaginary line, makes an angle of 66 ½ degree with its orbital plane. The earth takes about 24 hours to complete one rotation around its axis. The second motion of the earth is called revolution. It is the movement of the earth around the sun in a fixed path or orbit is called Revolution. Seasons are the consequences of revolution.
3) What would happen of the earth had no motion?
Ans. If the earth did not rotate the portion facing the sun would always experience day, thus bringing continuous warmth to the region. The other half would remain in darkness and be freezing cold all the time. Life would not have been possible in such extreme conditions. There would be no formation of days and nights and no seasons as well.
4) Explain the concept of a leap year.
Ans. It takes 365 ½ days for the earth to revolve around the sun. We consider a year as consisting of 365 days and ignore six hours for the sake of convenience. Six hours every day are added to make one day (24 hours) over a span of four years. This surplus day is added to the month of February. Thus every fourth year, February is pf 29 days instead of 28 days. Such a year with 366 days is called a leap year.
5) Explain Summer Solstice.
Ans. The rays of the sun fall directly on the Tropic of Cancer. As a result, these areas receive more heat. The areas near the poles receive less heat as the rays of the sun are slanting. The North Pole is inclined towards the sun and the places beyond the Arctic Circle experience continuous daylight for six months. The longest day and the shortest night at these places occur on the 21st June. At this time in the Southern Hemisphere all these conditions are reversed. Its winter season here. The nights are longer than the days. This position of the earth is called the Summer Solstice.
6) Explain Winter Solstice.
Ans. On 22nd December, the Tropic of Capricorn receives direct crays of the sun as the South Pole tilts towards it. As the sun’s rays fall vertically at the Tropic of Capricorn, a larger portion of the Southern Hemisphere gets light. Therefore, it is summer in the southern hemisphere with longer days and shorter nights. The reverse happens in the northen hemisphere. This position of the earth is called the Winter Solstice.
7) Explain Eqinox.
Ans. On 21st March and September 23rd direct rays of the sun fall on the equator. At this position, neither of the poles are tilted towards the sun, so the whole earth experiences equal days and equal nights. This is called an equinox. On 23rd September, it is autumn season in the northern hemisphere and spring season in the southern hemisphere. The opposite is the case on 21st March, when it is autumn in the southern hemisphere and spring on the northern hemisphere.
