Q2: Name the eight planets in order from the Sun and classify them.

The eight planets from the Sun are: 1. Mercury, 2. Venus, 3. Earth, 4. Mars (Inner planets - rocky, small) 5. Jupiter, 6. Saturn, 7. Uranus, 8. Neptune (Outer planets - gaseous, large) Inner planets are solid and close to the Sun. Outer planets are made of gases and liquids and are farther from the Sun.

Q3: What are the characteristics of Earth that make it unique?

Earth's unique characteristics: - Presence of liquid water essential for life - Suitable temperature range for life (neither too hot nor too cold) - Protective atmosphere that filters harmful radiation - One natural satellite - the Moon - Rich biodiversity - millions of living species - Presence of oxygen in atmosphere for respiration

Q4: Explain the phases of the Moon and why they occur.

Moon phases are caused by the Moon's position relative to Earth and Sun as it orbits Earth. As the Moon orbits: - New Moon: Moon is between Earth and Sun (not visible) - Crescent: small part is lit - Half Moon: half of the Moon is lit - Full Moon: entire side facing Earth is lit These phases repeat in a cycle of about 29.5 days. The Moon does not produce light; it reflects sunlight.

Q5: What are stars? How are they classified?

Stars are massive hot spheres of gas that produce their own light and heat through nuclear fusion. They are classified by: - Colour and temperature: red (cool), yellow (medium), white and blue (hot) - Size: dwarf stars (small), giant stars (large), supergiant stars (very large) - Brightness: determines by size and temperature Our Sun is a medium-sized yellow star.
