State whether True or False (i) Lunar eclipse occurs when the Sun comes between the Earth and the Moon. (ii) Sunrise happens earlier in Gujarat than in Jharkhand. (iii) In Chennai, the longest day occurs on the summer solstice. (iv) We should watch the solar eclipse directly with our naked eye. (v) Seasons occur due to the tilt of Earth's axis of rotation and its spherical shape. (vi) The Earth's revolution around the Sun causes day and night.
False. A lunar eclipse occurs when the Earth comes between the Sun and the Moon, blocking sunlight from reaching the Moon.
False. Sunrise happens earlier in Jharkhand than in Gujarat because Jharkhand is in the eastern part of India.
True. Chennai is in the Northern Hemisphere, where the longest day occurs around 21 June, known as the summer solstice.
False. Viewing the Sun directly during a solar eclipse can damage the eyes and cause blindness.
True. The tilt of Earth's axis and its spherical shape cause different parts of Earth to receive varying amounts of sunlight throughout the year, resulting in seasons.
False. Day and night are caused by the Earth's rotation on its axis, not by its revolution around the Sun.
Explanation
(i) The chapter states: 'As the Moon revolves around the Earth, sometimes the Earth can block the sunlight from reaching the Moon. This is known as a lunar eclipse.' The Earth, not the Sun, comes between the Sun and the Moon during a lunar eclipse. (ii) The chapter states: 'In India, sunrise first occurs in the eastern part and then in other parts.' Since Jharkhand lies in eastern India and Gujarat lies in western India, sunrise occurs earlier in Jharkhand. (iii) The chapter states: 'In the Northern Hemisphere, the longest day occurs around 21 June—this is known as summer solstice.' Chennai is located in the Northern Hemisphere, so this statement is true. (iv) The chapter warns: 'Thus, directly viewing solar eclipse must be strictly avoided. Also, do not view it through sunglasses, binoculars, or telescopes.' The Sun remains intense enough during an eclipse to cause serious eye damage. (v) The chapter states: 'The tilt of the Earth's axis and the spherical shape of the Earth gives rise to seasons.' This is the correct explanation for why seasons occur. (vi) The chapter clearly states: 'The Earth's rotation from West to East causes the day-night cycle.' Revolution around the Sun causes the changing seasons and the changing view of the night sky, not day and night.
