Are you a science geek? If yes, then you must play this interesting 'solar system quiz for grade 6'. The solar system is made up of the sun, the nine planets, and other celestial bodies that orbit around it. Our solar system is believed to have been formed over 4 billion years ago. This quiz below will test what you understood about the solar system and its related concepts. Take it up and see what you know so far.
Good luck!

• 1.

### I am between Mars and Jupiter.

• A.

The dwarf planets

• B.

The Galilean moons

• C.

Saturn's Rings

• D.

The asteroid belt

D. The asteroid belt
Explanation
The given statement "I am between Mars and Jupiter" indicates the location of the speaker. The asteroid belt is located between Mars and Jupiter in our solar system. It is a region that contains numerous small rocky objects called asteroids. Therefore, the correct answer is the asteroid belt.

### I have a spot on me that is bigger than earth.

• A.

True

• B.

False

A. True
Explanation
The statement claims to have a spot on the speaker that is bigger than the Earth. This statement is not scientifically possible as the Earth is much larger than any spot or mark on a human body. Therefore, the given answer "True" is incorrect.

### Comet's tails always point toward the sun.

• A.

True

• B.

False

B. False
Explanation
The statement "Comet's tails always point toward the sun" is false. A comet's tail does not always point directly toward the sun. The tail of a comet is formed by the solar wind, which is a stream of charged particles emitted by the sun. As the solar wind interacts with the comet's nucleus, it causes the tail to form and point away from the sun due to the force exerted on the charged particles. Therefore, the tail of a comet always points away from the sun, not toward it.

### I am called the red planet. People are planning to visit me.

• A.

Jupiter

• B.

Venus

• C.

Earth

• D.

Mars

D. Mars
Explanation
Mars is known as the red planet due to its reddish appearance caused by iron oxide (rust) on its surface. It is often referred to as the red planet because of its distinct reddish color. Additionally, there have been plans and missions in progress to send humans to Mars in the future, making it a popular destination for space exploration.

### State true or false- Gravity decreases as the distance between objects increases.

• A.

True

• B.

False

A. True
Explanation
Gravity decreases as the distance between objects increases because gravity is an attractive force that weakens with distance. The force of gravity is inversely proportional to the square of the distance between objects. As the distance increases, the gravitational force between the objects becomes weaker. This can be observed in everyday life, such as when objects are thrown upwards and eventually fall back to the ground due to the weakening gravitational force as they move farther away from the Earth's surface.

### Saturn is the only planet with rings.

• A.

True

• B.

False

B. False
Explanation
The statement is incorrect. Saturn is not the only planet with rings. Other planets in our solar system, such as Jupiter, Uranus, and Neptune, also have ring systems. Therefore, the correct answer is False.

• 7.

### Gravity increases between objects when the mass of either object decreases.

• A.

True

• B.

False

B. False
Explanation
The statement is false because gravity actually increases between objects when the mass of either object increases, not decreases. According to Newton's law of universal gravitation, the force of gravity is directly proportional to the product of the masses of the objects and inversely proportional to the square of the distance between them. Therefore, as the mass of either object increases, the force of gravity between them also increases.

### I'm the closest planet to the sun.

• A.

Venus

• B.

Earth

• C.

Jupiter

• D.

Mercury

D. Mercury
Explanation
Mercury is the closest planet to the sun. It is located between Venus and Earth, making it the correct answer. Venus, Earth, and Jupiter are all further away from the sun than Mercury.

### I am one of the moons of Jupiter.

• A.

Io

• B.

Pluto

• C.

Mercury

• D.

Titan

A. Io
Explanation
Io is the correct answer because it is indeed one of the moons of Jupiter. Discovered by Galileo Galilei in 1610, Io is the innermost and fourth-largest moon of Jupiter. It is known for its volcanic activity, with over 400 active volcanoes making it the most geologically active object in the solar system. Io's surface is covered with sulfur and has a yellowish color. It is also the most dense of Jupiter's moons and experiences intense tidal heating due to its elliptical orbit around the gas giant.

### I am one of the moons of Saturn.

• A.

Io

• B.

Pluto

• C.

Mercury

• D.

Titan

D. Titan
Explanation
Titan is the correct answer because it is one of the moons of Saturn. It is the largest moon of Saturn and the second-largest moon in the entire solar system. It is known for its thick atmosphere and is the only moon in the solar system to have a substantial atmosphere. Titan is also of great interest to scientists because it has similarities to early Earth, with its organic-rich atmosphere and potential for liquid lakes and oceans on its surface.

### I move through my orbit on my side like a football.

• A.

Jupiter

• B.

Saturn

• C.

Uranus

• D.

Neptune

C. Uranus
Explanation
Uranus is the correct answer because it is the only planet in our solar system that rotates on its side. This unique characteristic of Uranus is believed to be the result of a massive collision with a planet-sized object early in its formation, causing its axis of rotation to tilt at an extreme angle. This gives Uranus its distinct sideways orbit, similar to how a football moves when thrown.

### Name the coldest planet in our solar system.

• A.

Jupiter

• B.

Saturn

• C.

Uranus

• D.

Neptune

C. Uranus
Explanation
Uranus, the seventh planet from the Sun, holds the distinction of being the coldest in our solar system. Its low average temperatures are influenced by both its considerable distance from the Sun and its atmospheric composition, primarily consisting of hydrogen, helium, and methane. The methane absorbs sunlight, contributing to temperature regulation, but the planet's greater distance results in colder conditions. Additionally, Uranus's extreme axial tilt, rotating on its side, leads to unusual seasonal variations, further impacting its overall temperate climate.

### There are four of us. We are the ___________________ moons of Jupiter.

• A.

Galilean

• B.

Asteriod

• C.

• D.

Ort

A. Galilean
Explanation
The correct answer is "Galilean" because Galilean moons are the four largest moons of Jupiter, discovered by Galileo Galilei in 1610. They are named Io, Europa, Ganymede, and Callisto. These moons are significant because they were the first objects found to orbit another planet and played a crucial role in supporting the heliocentric model of the solar system.

• 14.

### Earth is the only planet known to have life.

• A.

True

• B.

False

A. True
Explanation
Earth is the only planet known to have life because it has the necessary conditions for life to exist. It is located at an ideal distance from the sun, which allows for the presence of liquid water, a key ingredient for life as we know it. Earth also has a protective atmosphere that shields it from harmful radiation and provides the necessary gases for respiration. Additionally, Earth's geology and climate support a wide variety of ecosystems and species, further indicating its uniqueness as a planet with life.
