• 1.

### How many planets are there in the solar system?

• A.

SEVEN

• B.

SIX

• C.

EIGHT

• D.

NINE

C. EIGHT
Explanation
There are eight planets in the solar system. The eight planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Pluto, which was previously considered the ninth planet, has been reclassified as a dwarf planet. Therefore, the correct answer is eight.

### PLANETS ORBIT

• A.

THE STARS

• B.

THE MOON

• C.

THE SUN

• D.

THE EARTH

C. THE SUN
Explanation
The sun is the correct answer because it is the central star in our solar system and all the planets, including the Earth, orbit around it. The moon, on the other hand, orbits around the Earth, not the sun. Therefore, the sun is the most accurate choice among the given options.

### THE LARGEST PLANET IN THE SOLAR SYSTEM IS

• A.

EARHT

• B.

MARS

• C.

JUPITER

• D.

SATURN

C. JUPITER
Explanation
Jupiter is the correct answer because it is the largest planet in the solar system. It has a diameter of about 143,000 kilometers, which is more than 11 times the diameter of Earth. Jupiter's immense size is due to its massive atmosphere and its composition, primarily made up of hydrogen and helium gases. It also has a strong gravitational pull, with more than twice the mass of all the other planets combined.

### THE TIME TAKEN  FOR THE EARTH TO SPINS ON ITS AXIS IS

• A.

A YEAR

• B.

A MONTH

• C.

A DAY

• D.

AN HOUR

C. A DAY
Explanation
The time taken for the Earth to spin on its axis is referred to as a day. This is the period of time it takes for the Earth to complete one full rotation, resulting in the cycle of day and night. A year is the time it takes for the Earth to orbit around the Sun, while a month is the time it takes for the Moon to complete one orbit around the Earth. An hour is a smaller unit of time within a day.

### The time taken for the Earth to orbit the Sun is

• A.

AN HOUR

• B.

A DAY

• C.

A MONTH

• D.

A YEAR

D. A YEAR
Explanation
The time taken for the Earth to orbit the Sun is a year. This is because the Earth takes approximately 365.25 days to complete one full orbit around the Sun. This period of time is known as a year and is the basis for our calendar system.

### The surface temperature of the Sun is about

• A.

60°C

• B.

600°C

• C.

6000°C

• D.

60000°C

C. 6000°C
Explanation
The surface temperature of the Sun is about 6000°C. This is because the Sun is a massive ball of hot, glowing gas that produces heat and light through the process of nuclear fusion. The temperature at the Sun's surface, known as the photosphere, is around 6000°C. This high temperature is necessary for the Sun to sustain its nuclear reactions and emit energy into space.

### The Sun rises in the

• A.

East and sets in the west

• B.

West and sets in the east

• C.

North and sets in the south

• D.

South and sets in the north

A. East and sets in the west
Explanation
The statement "The Sun rises in the east and sets in the west" is a well-known fact based on the Earth's rotation. As the Earth rotates from west to east, it appears as though the Sun rises in the east and sets in the west. This is because the Sun's light reaches different parts of the Earth at different times, creating the illusion of the Sun moving across the sky.

### It is night in CHINA when

• A.

Clouds cover the Sun

• B.

The Moon is out

• C.

It faces away from the Sun

• D.

The stars come out

C. It faces away from the Sun
Explanation
The correct answer is "it faces away from the Sun". This is because when the Moon faces away from the Sun, it is in a position where it is not receiving direct sunlight and therefore appears dark or invisible from Earth. This typically occurs during the night, when the Moon is on the opposite side of the Earth from the Sun.

### THE EARTH ROTATES IN IT OWN

• A.

BODY

• B.

ORBIT

• C.

AXIS

• D.

GALAXY

C. AXIS
Explanation
The Earth rotates on its axis, which is an imaginary line that runs through the North and South Poles. This rotation causes day and night as different parts of the Earth are exposed to the Sun's light. The axis is tilted at an angle of about 23.5 degrees, which is why we have seasons. As the Earth orbits around the Sun, the axis remains tilted in the same direction, resulting in the changing seasons throughout the year.
