Which of the follwoing planet is the smallest planet in Solar System?
- A.
Uranus
- B.
Neptune
- C.
Earth
- D.

Correct Answer
D. MercuryExplanation
Mercury is the smallest planet in the Solar System. It has a diameter of about 4,879 kilometers, making it slightly larger than Earth's moon. Despite its small size, Mercury is dense and has a relatively large iron core, which contributes to its high density. Its proximity to the Sun also means that it has a very short year, completing an orbit around the Sun in just 88 Earth days.Rate this question:

Who discovered the gravitational force?
Correct Answer
Isaac NewtonExplanation
Isaac Newton is credited with discovering the gravitational force. He formulated the laws of motion and the law of universal gravitation, which states that every object in the universe attracts every other object with a force that is directly proportional to their masses and inversely proportional to the square of the distance between them. Newton's groundbreaking work in physics revolutionized our understanding of gravity and laid the foundation for classical mechanics.Rate this question:

How many degrees does the Earth's axis tited?
- A.
42.5 degrees
- B.
24.5 degrees
- C.
23.5 degrees
- D.
22.5 degrees
Correct Answer
C. 23.5 degreesExplanation
The Earth's axis is tilted at an angle of 23.5 degrees. This tilt is responsible for the changing seasons and the variation in daylight hours throughout the year.Rate this question:

The equatorial area is cold throughout the year because this area receives overhead sunlight all year round.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The equatorial area is not cold throughout the year because it receives overhead sunlight all year round. In fact, the equatorial area is known for its hot and humid climate due to the direct and intense sunlight it receives. This region typically experiences high temperatures and little seasonal variation in temperature.Rate this question:

There are three types of solar eclipses: partial solar eclipse, total solar eclipse and _________ solar eclipse.
Correct Answer
annularExplanation
An annular solar eclipse occurs when the moon is farthest from the Earth and appears smaller than the sun, creating a "ring of fire" effect. During this type of eclipse, the moon does not completely cover the sun, resulting in a visible ring of sunlight around the moon.Rate this question:

How many time zones are there?
- A.
48
- B.
24
- C.
12
- D.
6
Correct Answer
B. 24Explanation
There are 24 time zones in the world. Each time zone represents a different region where the local time is set to a specific offset from Coordinated Universal Time (UTC). The Earth is divided into 24 longitudinal divisions, with each time zone covering approximately 15 degrees of longitude. As the Earth rotates, different regions experience different times of the day, and the time zones help standardize timekeeping across the globe for various purposes such as travel, communication, and scheduling.Rate this question:

The Earth rotates round an imaginary axis from east to west.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The Earth rotates round an imaginary axis from west to east. This rotation is responsible for the cycle of day and night. The direction of rotation can be determined by observing the movement of celestial objects in the sky.Rate this question:

When the Sun, The Earth and the Moon lie on or nearly on a straight line, and the Moon is between the Sun and the Earth, The light coming from the Sun to the Earth is blocked by the Moon. This results a __________eclipse.
Correct Answer
solarExplanation
When the Sun, Earth, and Moon align in a straight line with the Moon positioned between the Sun and Earth, the Moon blocks the light from the Sun reaching the Earth. This phenomenon is known as a solar eclipse.Rate this question:

It is dangerous to look directly at a solar eclipse with your bare eyes because the sunlight is still very intense and will hurt our eyes.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Looking directly at a solar eclipse with bare eyes is dangerous because the sunlight during an eclipse is still intense and can cause harm to our eyes. The eclipse does not reduce the intensity of sunlight, and the ultraviolet and infrared rays can damage the retina, leading to permanent vision loss. Therefore, it is important to use proper eye protection, such as eclipse glasses or solar filters, to safely view a solar eclipse.Rate this question:
