General Knowledge on Science Quiz For Grade 6 Questions and Answers
- 1.
Which planet is the biggest?
- A.
Saturn
- B.
Uranus
- C.
Jupiter
- D.
Mars
Correct Answer
C. JupiterExplanation
Jupiter is the biggest planet in our solar system. It has a diameter of about 143,000 kilometers, which is more than 11 times the diameter of Earth. Jupiter is a gas giant, known for its Great Red Spot, a massive storm that has been raging for centuries. Its size and mass are so significant that it has a strong gravitational influence on other objects in the solar system, including the asteroid belt. Jupiter's enormous size and distinctive features make it a fascinating subject of study in astronomy.Rate this question:

Which planet is the smallest?
- A.
Jupiter
- B.
Neptune
- C.
Earth
- D.
Mercury
Correct Answer
D. MercuryExplanation
Mercury is the smallest planet in our solar system. It has a diameter of about 4,880 kilometers, making it slightly larger than Earth's Moon. Despite its small size, Mercury has a significant gravitational pull and a heavily cratered surface, similar to the Moon. Its proximity to the Sun results in extreme temperature variations, with scorching heat during the day and freezing cold at night. Mercury's small size and unique characteristics make it an intriguing planet for scientists studying the solar system's formation and evolution.Rate this question:

How long does it take for Jupiter to move around the sun?
- A.
About 6 Earth years
- B.
About 12 Earth years
- C.
About 4 Earth years
- D.
About 8 Earth Years
Correct Answer
B. About 12 Earth yearsExplanation
Jupiter takes about 12 Earth years to complete one orbit around the Sun. This lengthy orbital period is due to its significant distance from the Sun, approximately 778 million kilometers (484 million miles) away. Jupiter's slow journey around the Sun is influenced by its massive size and strong gravitational field, which also affects the orbits of nearby objects, including some asteroids. Understanding Jupiter's orbital period helps astronomers study the dynamics of our solar system and the gravitational interactions between celestial bodies.Rate this question:

What time will it be in New York if it is 12 noon at Greenwich?
- A.
10: 00 pm
- B.
8: 00 am
- C.
7: 00 am
- D.
11: 00 am
Correct Answer
C. 7: 00 amExplanation
If it is 12 noon at Greenwich (Greenwich Mean Time, GMT), the time in New York (Eastern Standard Time, EST) would be 7:00 am. New York is typically 5 hours behind Greenwich Mean Time. This time difference can vary during Daylight Saving Time when clocks are set forward by one hour, making the difference 4 hours instead. Understanding time zones is crucial for coordinating activities and communication across different regions of the world.Rate this question:

Which is a sphere of the land on Earth?
- A.
Stratosphere
- B.
Lithosphere
- C.
Mesosphere
- D.
None of the above
Correct Answer
B. LithospHereExplanation
The lithosphere is the sphere of the land on Earth. It comprises the Earth's crust and the uppermost part of the mantle, forming the solid, outer layer of the planet. The lithosphere is divided into tectonic plates, which float on the semi-fluid asthenosphere beneath them. This layer includes all the landforms, such as mountains, valleys, and plains, and is crucial for supporting terrestrial life. The other terms, stratosphere and mesosphere, refer to layers of the Earth's atmosphere, not the land. Understanding the lithosphere helps in studying geology, tectonics, and Earth's physical features.Rate this question:

Which of the following is the most abundant gas in the Earth's atmosphere?
- A.
Oxygen
- B.
Carbon Dioxide
- C.
Nitrogen
- D.
Argon
Correct Answer
C. NitrogenExplanation
Nitrogen is the most abundant gas in the Earth's atmosphere, making up about 78% of the air we breathe. Oxygen is the second most abundant, accounting for about 21%, while Argon and Carbon Dioxide make up much smaller percentages. Nitrogen is essential for life, playing a critical role in the biosphere and as a key component of amino acids and proteins.Rate this question:

Which river is the world's longest?
- A.
Nile
- B.
Amazon
- C.
Mississippi
- D.
River Thames
Correct Answer
A. NileExplanation
The Nile River is the longest river in the world. It flows through northeastern Africa, primarily through Egypt and Sudan. The Nile is famous for its role in ancient Egyptian civilization, providing water for agriculture and transportation. It stretches over 6,650 kilometers (4,130 miles) in length. The river begins in the East African Rift and flows northward into the Mediterranean Sea. Its length surpasses other major rivers like the Amazon in South America, the Mississippi in North America, and the River Thames in England, making it the longest river globally.Rate this question:

In which ocean is the Mariana Trench (deepest location on Earth)?
- A.
Atlantic ocean
- B.
Indian ocean
- C.
Pacific ocean
- D.
None of these
Correct Answer
C. Pacific oceanExplanation
The Mariana Trench, the deepest location on Earth, is located in the Pacific Ocean. It reaches a maximum known depth of about 36,070 feet (10,994 meters) at a point known as the Challenger Deep. The trench is situated east of the Mariana Islands and is a significant site for scientific exploration and study. Its extreme depths present unique conditions that challenge our understanding of marine biology, geology, and the limits of life on Earth. The Mariana Trench is a focal point for deep-sea research due to its mysterious and largely unexplored environment.Rate this question:

Which of these animals has teeth outside its mouth too?
- A.
Tiger
- B.
Deer
- C.
Snake
- D.
Elephant
Correct Answer
D. ElepHantExplanation
Elephants have teeth outside their mouths too, which are known as tusks. These elongated incisor teeth grow continuously throughout an elephant's life and can protrude several feet from their mouths. Tusks serve various purposes, including digging, lifting objects, and defense. They are made of ivory, a valuable material that unfortunately leads to illegal poaching and endangerment of elephants.Rate this question:

Which of these is an amphibian?
- A.
Frog
- B.
Crocodile
- C.
Lion
- D.
Human
Correct Answer
A. FrogExplanation
The correct answer is Frog because frogs are amphibians. Amphibians are cold-blooded vertebrates that typically have a moist, glandular skin, lay eggs in water, and undergo a metamorphosis from a juvenile aquatic stage to an adult terrestrial stage. Frogs have adaptations that allow them to live both in water and on land, such as their ability to breathe through their skin and their unique life cycle that involves a tadpole stage in water and an adult stage on land.Rate this question:

Which planet is also known as the morning and evening star?
- A.
Venus
- B.
Mars
- C.
Mercury
- D.
Jupiter
Correct Answer
A. VenusExplanation
Venus is known as both the morning star and the evening star because it is one of the brightest objects in the sky and can be seen shining brightly just before sunrise and just after sunset. This visibility occurs due to Venus's orbit being closer to the Sun than Earth's orbit, making it appear near the Sun in the sky. Its bright, reflective cloud cover contributes to its prominent visibility during these times, earning it the names morning star and evening star.Rate this question:

What is the largest ocean in the world?
- A.
Arctic Ocean
- B.
Indian Ocean
- C.
Pacific Ocean
- D.
Atlantic Ocean
Correct Answer
C. Pacific OceanExplanation

It stretches from the Arctic Ocean in the north to the Southern Ocean in the south and is bounded by Asia and Australia on the west and the Americas on the east. The Pacific Ocean is not only the largest but also the deepest ocean, containing the Mariana Trench, the deepest point on Earth. Its vast size and depth play a crucial role in global climate, marine biodiversity, and Earth's water cycle.Rate this question:
