GRADE 5 CONSOLIDATED WORKSHEET
SUBJECT: SCIENCE
WEEK 12
TOPIC: EARTH AND SPACE – THE SOLAR SYSTEM
---
1. Define the term “solar system”
✔ Answer: The solar system is a collection of celestial bodies that orbit around the Sun, including planets, moons, asteroids, comets, and other objects bound by gravity.
🔹 *Explanation:* The solar system consists of the Sun at the center, with eight planets and many smaller bodies orbiting it due to gravitational forces.
---
2. There are ________ planets in the solar system.
✔ Answer: 8
🔹 *Explanation:* Since Pluto was reclassified as a dwarf planet in 2006 by the International Astronomical Union (IAU), there are now eight officially recognized planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.
---
3. The hottest planet in the solar system is ________, while the coldest planet in the solar system is ________.
✔ Answer: Venus; Neptune
🔹 *Explanation:*
- Venus is the hottest planet because its thick atmosphere traps heat through the greenhouse effect, even though it's not the closest to the Sun.
- Neptune is the coldest planet because it's the farthest from the Sun and receives very little solar energy.
---
4. The fourth planet away from the sun is ________, and it is often referred to as the _________.
✔ Answer: Mars; Red Planet
🔹 *Explanation:* Mars is the fourth planet from the Sun. It's called the "Red Planet" due to the iron oxide (rust) on its surface, which gives it a reddish appearance.
---
5. The ________ is in the centre of the solar system.
✔ Answer: Sun
🔹 *Explanation:* The Sun is the central star of the solar system. Its gravity holds all the planets and other objects in orbit around it.
---
6. Scientists decide to visit the planet that has life on it. Which planet are they more likely to visit?
✔ Answer: Earth
🔹 *Explanation:* Earth is the only known planet where life exists. It supports a wide variety of living organisms, including humans.
---
7. Identify the planet which has rings around it ________.
✔ Answer: Saturn
🔹 *Explanation:* Saturn is most famous for its prominent and visible ring system made of ice, rock, and dust particles. Other gas giants (Jupiter, Uranus, Neptune) also have rings, but Saturn's are the most striking.
---
8. ________ is known as the King of Moons.
✔ Answer: Jupiter
🔹 *Explanation:* Jupiter has the largest number of moons among all planets in the solar system—over 90 confirmed moons. It is therefore often called the "King of Moons."
---
9. ________ is the most distant planet in the solar system.
✔ Answer: Neptune
🔹 *Explanation:* Neptune is the eighth and farthest planet from the Sun, located about 4.5 billion kilometers away.
---
10. ________ is the smallest planet in the solar system and the ________ planet to the sun.
✔ Answer: Mercury; closest
🔹 *Explanation:* Mercury is the smallest planet (about 4,880 km in diameter) and orbits the Sun at an average distance of about 58 million km—making it the closest planet to the Sun.
---
11. Uranus has ________ moons.
✔ Answer: 27 (as of current scientific data)
🔹 *Explanation:* As of recent observations, Uranus has 27 known moons. They are mostly small and icy, with the largest being Titania and Oberon.
---
12. The tilted planet is ________.
✔ Answer: Uranus
🔹 *Explanation:* Uranus is known as the "tilted planet" because it rotates on its side—its axis is tilted at about 98 degrees relative to its orbital plane. This means it essentially rolls around the Sun on its side.
---
1. The solar system is a group of celestial bodies orbiting the Sun.
2. 8
3. Venus; Neptune
4. Mars; Red Planet
5. Sun
6. Earth
7. Saturn
8. Jupiter
9. Neptune
10. Mercury; closest
