Passage: Shadows and Sun Movement

One morning in Kanniyakumari, Rashmika noticed that shadows of coconut trees were long in the morning and shorter in the afternoon.

Q1. What causes the Sun to appear to move across the sky during the day?
(a) Revolution of the Earth around the Sun
(b) Rotation of the Sun
(c) Rotation of the Earth on its axis
(d) Revolution of the Moon around the Earth

Answer: (c)
Difficulty: Easy
Explanation: The apparent movement of the Sun from east to west is due to the Earth’s rotation from west to east.

(a) Constant day everywhere
(b) Seasons would not occur

Q4. What instrument was used in the classroom to explain Earth’s rotation?
(a) Globe
(b) Telescope
(c) Compass
(d) Periscope

Answer: (a)
Difficulty: Easy
Explanation: A globe is used to simulate Earth’s rotation and revolution to explain such phenomena.

Case Study Question 2:

Passage: Understanding Eclipses

During a solar eclipse, the Moon comes between the Earth and the Sun, blocking sunlight from reaching parts of the Earth. In contrast, a lunar eclipse occurs when the Earth comes between the Sun and the Moon. Raghav read that lunar eclipses are visible from a larger area than solar eclipses.

(b) The Earth casts a larger shadow
(c) The Moon reflects more light

(b) Watching it indirectly with a pinhole camera
(c) Watching it directly with the naked eye
(d) Observing it through a telescope with a solar filter
