1.
How many planet's are in our Solar System ?
Correct Answer
D. 8
Explanation
There are 8 planets in our Solar System.
2.
Which planet is the 5th furthest away from the Sun ?
Correct Answer
B. Jupiter
Explanation
Jupiter is the 5th furthest planet from the Sun. It is located after Mars, Saturn, Uranus, and Neptune in terms of distance from the Sun.
3.
Planet's that are further from the Sun move; more slowly and they take more time to complete an orbit.
Correct Answer
A. True
Explanation
Planets that are further from the Sun move more slowly and take more time to complete an orbit because of the gravitational pull exerted by the Sun. According to Kepler's laws of planetary motion, the farther a planet is from the Sun, the weaker the gravitational force it experiences, resulting in a slower orbital speed. This is why outer planets like Neptune and Uranus have much longer orbital periods compared to inner planets like Mercury and Venus. Therefore, the statement is true.
4.
How long does it take Mercury to complete an orbit round the Sun ?
Correct Answer
C. 88 Earth Days
Explanation
Mercury takes approximately 88 Earth days to complete one orbit around the Sun. This is because Mercury is the closest planet to the Sun and has a shorter orbital period compared to other planets in our solar system. The gravitational pull of the Sun causes Mercury to move at a faster speed, resulting in a shorter orbital period.
5.
How long does it take Earth to make one complete turn on its axis (a day) ?
Correct Answer
E. 24 hours
Explanation
The correct answer is 24 hours. This is because Earth takes approximately 24 hours to make one complete rotation on its axis, resulting in a day.
6.
How many hours are in a week (7 days) ?
Correct Answer
C. 168 hours
Explanation
There are 24 hours in a day and 7 days in a week. To calculate the total number of hours in a week, we multiply 24 by 7, which equals 168 hours.
7.
How many hours are ther in a month, which has 31 days ?
Correct Answer
A. 744 hours
Explanation
There are 24 hours in a day, so in a month with 31 days, there would be 31 multiplied by 24, which equals 744 hours.
8.
How many days there are in a year ?
Correct Answer
B. 365 days
Explanation
The correct answer is 365 days. In a regular year, there are 365 days, consisting of 12 months with varying numbers of days. However, in a leap year, which occurs every four years, there is an extra day added to the month of February, making it 366 days in total.
9.
How long does it take Neptune to orbit the Sun ?
Correct Answer
B. 164 Earth years
Explanation
Neptune takes 164 Earth years to orbit the Sun. This is because Neptune is located much farther from the Sun compared to Earth, so it takes a significantly longer time to complete one orbit.
10.
When the Northern hemisphere is tilted towards the Sun what season is it ?
Correct Answer
E. Summer
Explanation
When the Northern hemisphere is tilted towards the Sun, it experiences summer. This is because the tilt of the Earth's axis causes the Sun's rays to hit the Northern hemisphere at a more direct angle, resulting in longer days and warmer temperatures. This phenomenon occurs around June 21st, known as the summer solstice, in the Northern hemisphere.
11.
When the Souther hemisphere is tilted towards the Sun, what season is it for the Northern hemisphere ?
Correct Answer
C. Winter
Explanation
When the Southern hemisphere is tilted towards the Sun, it is winter for the Northern hemisphere. This is because the tilt of the Earth's axis causes one hemisphere to receive more direct sunlight while the other receives less. When the Southern hemisphere is tilted towards the Sun, the Northern hemisphere is tilted away, resulting in less sunlight and colder temperatures, which is characteristic of winter.
12.
How many phases of the Moon are there ?
Correct Answer
C. 8
Explanation
There are eight phases of the Moon. The phases of the Moon refer to the different shapes or appearances of the Moon as it orbits around the Earth. These phases include the New Moon, Waxing Crescent, First Quarter, Waxing Gibbous, Full Moon, Waning Gibbous, Third Quarter, and Waning Crescent. Each phase represents a different amount of the Moon's illuminated surface that is visible from Earth.
