The following questions consist of two statements – Assertion (A) and Reason (R). Answer these questions by selecting the correct option:
(a) Both A and R are true and R is the correct explanation of A.
(b) Both A and R are true but R is not the correct explanation of A.
(c) A is true but R is false.
(d) A is false but R is true.
1. (A): The Sun appears to rise in the east and set in the west.
(R): The Earth rotates from west to east.
Answer:
(a) Both A and R are true and R is the correct explanation of A.
2. (A): Seasons occur because the Earth is sometimes closer to the Sun and sometimes farther.
(R): Earth’s orbit is nearly circular.
Answer:
(d) Seasons do not occur due to the varying distance between the Earth and the Sun. They arise because of the tilt of the Earth’s axis and its spherical shape.
3. (A): Different constellations are visible in the night sky at different times of the year.
(R): The Earth revolves around the Sun, changing the view of the night sky.
Answer:
(a) Both A and R are true and R is the correct explanation of A.
4. (A): When the northern hemisphere is tilted towards the Sun, it is summer there.
(R): The seasons are caused by the tilt of the Earth’s axis and the spherical shape of the Earth.
Answer:
(a) Both A and R are true and R is the correct explanation of A.
5. (A): During June, the Southern Hemisphere experiences winter.
(R): At this time, the Southern Hemisphere tilts away from the Sun.
Answer:
(a) Both A and R are true and R is the correct explanation of A.
6. (A): Solar eclipses are visible only from a small region on the Earth.
(R): The Moon is much smaller than Earth, so its shadow formed on Earth covers only a small region.
Answer:
(a) Both A and R are true and R is the correct explanation of A.
7. (A): When it is daytime in India, it can be nighttime in the USA at the same moment.
(R): This happens because the Earth does not rotate but only revolves around the Sun.
Answer:
(a) Both A and R are true and R is the correct explanation of A.
8. (A): During some months, the Sun never sets at the poles, while during others, it never rises.
(R): At the poles, the tilt of Earth’s axis keeps one pole continuously facing the Sun for about six months, and the other in darkness.
Answer:
(a) Both A and R are true and R is the correct explanation of A.
