Section -B
Q3. Very Short Answer Type Questions:
i.) Equinox means equal day and night. On 21st March and 23rd September, the rays of the sun are directly over the earth causing almost equal duration of day and night all over the earth.
ii.) The year which contains an additional day that is 366 days is known as Leap year.
iii.) Rotation of earth on its axis causes day and night.
iv.) The two types of motion of earth are rotation and revolution.
v.) The axis of the earth forms an angle of 66 ½ degree angle.
vi.) If the earth stops rotating then no life will remain alive.
Section -C
Q4. Short Answer Type Questions:
i.) On 22nd December the Tropic of Capricorn (231/2-degree South) receives direct sun rays as the South Pole is tilted towards the Sun. This causes longer days and shorter nights and summer season in the Southern Hemisphere. The Northern Hemisphere experiences winter with longer nights and shorter nights
ii.) The earth revolves around the sun in an elliptical orbit and earth’s axis is tilted by 23.5° in the east direction on its axis. The revolution and tilt of the axis cause seasons. A year is divided into four seasons – Spring, Summer, Autumn and Winter. Seasons change with change in the position of earth.
iii.) Polar day is a phenomenon that takes place when the duration of night lasts for more than 24 hours. This is experienced in polar areas. Polar days takes place when the sun is positioned over polar area for more than 24 hours causing long duration of days which is also known as midnight sun.
Section -D
Q5. Long Answer Type Questions:
i.) Rotation- The movement of earth on its axis is called Rotation. The earth takes 24 hours to complete one rotation and this period is called as earth-day. The rotation of earth causes day and night.
Revolution- The second motion of the earth is known as revolution. The earth revolves around the sun on its orbit and it takes 365 days and 6 hours to complete one revolution. The revolution of the earth causes different seasons.
ii.) A year is divided into 4 seasons- summer, winter, spring and autumn seasons. Seasons change as there is change in the position of the earth while moving around the sun. The revolution of the earth on its orbit and the inclination of the earth’s axis in a fixed direction cause the seasons. The earth receives different amount of sunlight at different time of the year and thus experiences different seasons.
Section -E
Q6. Make the following diagrams: –
ii.) Formation of day and night.
