## NCERT SOLUTIONS

Question 1: Answer the following questions briefly.
(a) What is the angle of inclination of the earth’s axis with its orbital plane? Ans-66.5 degrees
(b) Define rotation and revolution. Ans-The movement of earth on its axis is known as rotation and its movement around the Sun in an elliptical path is called revolution.
(c) What is a leap year? Ans- A year which has 366 days is known as leap year.
(d) Differentiate between the Summer and Winter Solstice. Ans-The summer solstice is the longest day of the year, and the winter solstice is the shortest day of the year. The summer solstice occurs when the sun is at its highest point in the sky, and the winter solstice occurs when the sun is at its lowest point in the sky.
(e) What is an equinox? Ans-It is the position of the Earth during spring and autumn.
(f) Why does the Southern Hemisphere experience winter and Summer Solstice in different times than that of the Northern Hemisphere? Ans-The Earth is tilted at an angle of about 23.5 degrees as it orbits the sun. This tilt stays constant throughout the year.This tilt means that different parts of the Earth receive different amounts of sunlight at different times of the year.When the North Pole is tilted towards the sun, it receives more direct sunlight, experiencing summer solstice. Meanwhile, the South Pole is tilted away, receiving less direct sunlight and experiencing winter solstice. This happens around June 21st.(g) Why do the poles experience about six months day and six months night? Ans-The poles experience six months of day and six months of night because of the Earth’s tilt on its axis.
Question 2: Tick the correct answer.

(a) The movement of the earth around the sun is known as
(i) Rotation
(ii) Revolution

(i) 21 March
(ii) 21 June
(iii) 22 December

(c) Christmas is celebrated in summer in
(i) Japan

(c) (iii) Australia
(d) (ii) Revolution
Question 3: Fill in the blanks.

(a) A leap year has _ number of days. Ans- 366 days
