Solutions-Class-6-General Science-Chapter-8-Beyond the Sky-Maharashtra Board

Material: natural colours made from things around them, such as charcoal, soot, red and yellow ochre (coloured earth/minerals) and chalk, mixed with animal fat or water.

Reason: to record important events (a comet, hunts, animals), to share knowledge with others and to pass it on to future generations. (Textbook gives this as a thinking question; the answer is based on general knowledge.)

They travel beyond the sky into space, far above the atmosphere, to study the Moon, Mars and the Sun. A jet aircraft flies only within the sky (the atmosphere) and needs air to fly, so it is not a spacecraft.

Lightning occurs in the sky, inside the atmosphere, in clouds that are only a few km above the ground

Andromeda (Devyani). (It is slightly bigger than our Akashganga and has been known for over 4,000 years.)

Aryabhatta. (First explained that Earth rotates on its axis and revolves around the Sun; author of 'Aryabhattiya'.)

The Sun. (Located approximately 14 crore kilometers from Earth.)

Comet. (Revolves elliptically around the Sun and develops a gaseous tail when heated.)

FALSE.

Correct Statement: Stars are self-luminous celestial bodies that produce and emit their own light, heat, and radiation. Planets do not have their own light.

FALSE.

Correct Statement: The Pole Star (Dhruva Tara) is situated directly above the North Pole in the northern direction, and is completely invisible from the southern hemisphere.

TRUE.

Justification: When an exceptionally large rock enters the atmosphere, its inner core survives atmospheric friction, impacts the Earth as a meteorite, and forms an impact crater (e.g. Lonar Lake in Buldhana).

Chandrayaan-1 : 2008  ::  Mangalyaan mission : 2014.

Aditya L1 : Study of the Sun  ::  NISAR : Study of the Earth (forests, climate change, earthquake effects on Earth's crust, melting glaciers, disaster management)

Correct Answer: 4. All of the above.

Scientific Justification: Successful sky watching demands zero artificial light pollution to enhance contrast, optical magnification to resolve craters and moons, and observing western targets first because western objects set below the horizon early.

1. Seeing a comet brings danger, disaster or bad luck.
2. Seeing a falling meteor (shooting star) brings good luck, or making a wish on it will come true.
3. Planets and stars rising, setting or changing position decide a person's fate or affect daily life.
4. Eclipses are harmful or bring misfortune (e.g. people avoid eating or going out).
5. Stars falling mean a person has died.

Scientific fact: these events are natural and do not affect human life.

(Items 3–5 are common beliefs added for completeness; the textbook itself names the first two.)
