- E.
Mercury, Crypton, LB-426, Terra
Correct Answer
C. Mercury, Venus, Earth, MarsExplanation
The correct answer is Mercury, Venus, Earth, and Mars. These four planets are known as the inner planets because they are located closer to the Sun compared to the outer planets. Mercury is the closest planet to the Sun, followed by Venus, Earth, and Mars.Rate this question:

What is the primary difference between the inner planets and outer planets?
- A.
The inner planets are furthest away from the sun
- B.
The inner planets are rocky planets
- C.
The inner planets are gas giants
- D.
The inner planets all have breathable atmospheres for Human Beings
Correct Answer
B. The inner planets are rocky planetsExplanation
The primary difference between the inner planets and outer planets is that the inner planets are rocky planets. This means that they are composed mainly of solid material, such as rock and metal. In contrast, the outer planets are predominantly gas giants, which means they are composed mostly of gases, such as hydrogen and helium. The rocky composition of the inner planets gives them a different physical structure and surface features compared to the gas giants of the outer planets.Rate this question:

Which of the inner planets is considered Earth's Twin?
- A.
Mercury
- B.
Venus
- C.
Mars
- D.
Jupiter
- E.
Pluto
Correct Answer
B. VenusExplanation
Venus is considered Earth's twin because it is similar in size, composition, and gravity. Both planets have a similar rocky structure and a dense atmosphere. Venus also has a similar distance from the Sun, resulting in comparable temperatures. Additionally, Venus and Earth are the only two planets in the solar system that have active volcanoes. However, despite these similarities, Venus has a much harsher environment with extreme temperatures and a thick atmosphere of toxic gases.Rate this question:

- A.
Mars
- B.
Mercury
- C.
Venus
- D.
Earth
- E.
Nepturn
Correct Answer
A. MarsExplanation
Mars is the correct answer because it is the fourth planet from the Sun, making it the furthest inner planet from the Sun. Mercury is the closest inner planet to the Sun, followed by Venus and then Earth. Neptune is not an inner planet, it is an outer planet located much further away from the Sun.Rate this question:

The inner planets and outer planets are divided by a boundary of debris known as the what?
- A.
Kiper Belt
- B.
Asteroid Belt
- C.
Comet Debris
- D.
Solar Flares
- E.
The Big Bang
Correct Answer
B. Asteroid BeltExplanation
The correct answer is Asteroid Belt. The inner planets, including Mercury, Venus, Earth, and Mars, are located closer to the Sun and are separated from the outer planets, such as Jupiter, Saturn, Uranus, and Neptune, by a region called the Asteroid Belt. The Asteroid Belt is a collection of small rocky objects, known as asteroids, that orbit the Sun between Mars and Jupiter. These asteroids are remnants from the early formation of the solar system and are believed to be the building blocks that never formed into a planet.Rate this question:
