Which of the following planets has the highest surface temperature?
- A.
Jupiter
- B.
Pluto
- C.
Mercury
- D.
Saturn
Correct Answer
C. MercuryExplanation
Mercury has the highest surface temperature among the given options. This is because it is the closest planet to the Sun, and its thin atmosphere cannot retain heat, causing extreme temperature variations. During the day, temperatures can reach up to 800 degrees Fahrenheit (430 degrees Celsius), while at night, temperatures can drop to -290 degrees Fahrenheit (-180 degrees Celsius). This extreme temperature range makes Mercury the hottest planet in our solar system.Rate this question:

The planets in Solar System do not give off light of their own. They reflect from the _____.
- A.
Moon
- B.
Sun
- C.
Earth
- D.
Comet
Correct Answer
B. SunExplanation
The planets in the Solar System do not have their own source of light, so they rely on reflecting light from another object. The Sun is the primary source of light in the Solar System, emitting vast amounts of light and heat. The planets reflect this light from the Sun, allowing us to see them in the night sky.Rate this question:

Which of the following acts as a layer that protects the Earth from harmful rays of the Sun?
- A.
Clouds
- B.
Gravity force
- C.
Vacuum
- D.
Atmosphere
Correct Answer
D. AtmosphereExplanation
The atmosphere acts as a layer that protects the Earth from harmful rays of the Sun. It contains various gases that absorb and scatter the Sun's ultraviolet (UV) radiation, preventing it from reaching the Earth's surface in excessive amounts. The ozone layer, which is part of the atmosphere, plays a crucial role in absorbing most of the Sun's harmful UV radiation. Without the atmosphere, the Earth would be exposed to intense UV radiation, leading to detrimental effects on life forms and the environment.Rate this question:

From the Earth, the Moon looks bigger than the Sun. Which of the following is the reason?
- A.
The Sun is very small
- B.
The Sun is nearer to the Earth
- C.
The Moon is Nearer to the Earth
- D.
The sunlight is brighter than the moonlight
Correct Answer
C. The Moon is Nearer to the EarthExplanation
The reason the Moon appears bigger than the Sun from Earth is that the Moon is closer to the Earth. Distance plays a crucial role in how objects appear in the sky. Even though the Sun is much larger than the Moon, its distance from Earth makes it appear smaller in comparison. Since the Moon is relatively closer to the Earth, it appears larger in the sky.Rate this question:

Which of the following statements about the Moon are true?i The Moon is the Earth's natural satelliteii We can see a full Moon every nightiii There is no oxygen to support life on Mooniv The Moon is twice the size of the Earth
- A.
I and iii
- B.
Ii and iv
- C.
I, ii, and iii
- D.
Ii,iii and iv
Correct Answer
A. I and iiiExplanation
The correct answer is "i and iii." Statement i is true because the Moon is indeed the Earth's natural satellite. Statement iii is true because there is no oxygen on the Moon, making it unable to support life.Rate this question:

Which of the following factors explain why the Earth can support lives?i it has airii it has wateriii it has a large surfaceiv it has suitable temperature
- A.
I and iii
- B.
Ii and iv
- C.
I, ii and iv
- D.
All above
Correct Answer
C. I, ii and ivExplanation
The Earth can support life because it has air, water, and a suitable temperature. Air is necessary for organisms to breathe, while water is essential for various biological processes. The large surface area of the Earth provides ample space for diverse ecosystems to exist. Additionally, the Earth's suitable temperature allows for the existence of liquid water, which is crucial for life as we know it. Therefore, options i, ii, and iv are the correct factors explaining why the Earth can support life.Rate this question:

Which of the following statements are true?i Jupiter is the largest planetii the nine planets give off light of their owniii the size of the Sun is about 100 times relative to the size of the Earthiv the distance of a planet from the Sun will affects how hot or cold it is
- A.
I and iii
- B.
Ii and iv
- C.
I, iii, and iv
- D.
All above
Correct Answer
C. I, iii, and ivExplanation
The statement "Jupiter is the largest planet" is true because Jupiter is the largest planet in our solar system. The statement "the size of the Sun is about 100 times relative to the size of the Earth" is also true as the Sun is approximately 100 times larger than Earth in terms of diameter. Lastly, the statement "the distance of a planet from the Sun will affect how hot or cold it is" is true because the distance from the Sun determines the amount of sunlight and heat a planet receives, thus affecting its temperature. Therefore, the correct answer is i, iii, and iv.Rate this question:

- A.
A star
- B.
A planet
- C.

What causes the big crater to form?
- A.
A comet
- B.
A planet
- C.
An asteroid
- D.
A mateorite
Correct Answer
D. A mateoriteExplanation
A meteorite is the correct answer because when a meteoroid (a small piece of rock or metal from space) enters the Earth's atmosphere and survives the intense heat and friction, it is called a meteorite. When a meteorite impacts the Earth's surface, it can create a large crater due to the force and energy released upon impact. Comets, planets, and asteroids can also collide with the Earth, but in this case, a meteorite is specifically mentioned as the cause of the big crater formation.Rate this question:

- A.
A comet
- B.
A meteor
- C.
An asteroid
- D.
A meteorite
Correct Answer
B. A meteorExplanation
When an object enters the Earth's atmosphere and burns brightly, it is known as a meteor. Meteors are small celestial bodies that burn up upon entering the Earth's atmosphere, creating a streak of light in the sky commonly referred to as a shooting star. Comets, asteroids, and meteorites are different types of celestial objects, but only meteors exhibit the described behavior of burning brightly in the atmosphere.Rate this question:
